ASSEMBLY INSTRUCTlONS
This heavy duty machine is shipped to you in a single case, with the
completely assernbled table and tabletop on a skid, and the boxed carriage
and sewing head each strapped to it. The accessories are packed in with the
sewing head.
TS
When setting up the table in proper location, preparatory to putting the
carriage on the tracks, remember that the legs are adjustable for height, to
take care of irregularities in the floor, and also perhaps to regulate to the best
suitable height for the operator. An adjusting screw with its lock nuts is found
on the bottom of each leg.
PA
R
To assemble the carriage to the table, first remove the roller and stud 0030A
(Plate 14) from the bracket at upper track level. This roller normally runs
against the narrow inside (back) face of the upper track. It must be removed
to get the carriage on the track. When the carriage has been lifted on the
track, rilnning on its castor rollers, replace the roller and stud, and the
carriage will be properly in place.
AT
Attach the sewing head to the carriage, by means of the four hex head
screws provided. These are put in from the bottom, and on two of them a
little reaching under the carriage upper tilt plate will have to be done. The
cover over the drive wheel and its belt should be removed so that the belt
can be fastened over the pulley. (Plate 20). The screws fasten the belt cover
on again.
The larnp holder bracket is fastened on the side of the head opposite the
operator's position. Two screws for fastening the bracket will be found in
place. The wire to plug in the work light should be fastened in two places
with plastic loops before being plugged in on the outlet on the carriage.
M
Next, fasten the (Lower) thread cone platter and the (Upper) tape reel on the
same side of the carriage, away from the table. A rubber guide loop for the
main power wire is attached to the head with the same screw used to fasten
the :ape ;eel.
Three thread guides, consisting of a wire with a loop at each end are
fastened to the carriage and sewing head below the tape reel. The righthand (needle) thread uses two thread guides, a long one on the carriage and
a shorter one on the head; the latter to the left to by-pass the reel. The
looper thread, further to the left, uses only one (long) thread guide on the
carriage. These guide the two threads to the bracket on top of the head.
The looper thread (on the left) passes from the bracket down through a tube
provided. Just thread any needle to the thread and use it as a weight to pass
the thread down through the tube to its lower tension post.
The other (needle) thread goes from the upper tension post over various
thread guides across the top of 'the head and down the nose to the needle.
The sewing head comes to you fully threaded, so please observe the various
thread guides. For further threading information, consult fig.6.
Connect the carriage to the slip ring rod and plug in the electrical connection.
TS
Check that the mains electricity supply is suitable for the machine. The
required supply is shown on the label by the contactor.
Contact the mains supply and do the following checks:-
.
FIRST CHECK AFTER INSTALLATION
PA
R
After the machine has been installed and the electricity supply connected,
check for correct rotation.
Set the clutch hand lever to the engaged position and give the carriage a little
push to make sure the dog clutch is engaged.
Press the knee pad in as far as it will go and switch on.
The motor will be heard running.
Let the knee pad out slowly and the carriage should move towards you.
AT
If it moves away from you, switch off, disconnect the supply and reverse the
connection of two of the three lines.
M
Repeat the above instructions, and when the carriage moves towards you
check that the hand-wheel on ,the sewing head turns in an anti-clockwise
direction, viewed from the drive pulley end of the head. Fig.6. If it does not
turn correctly, check that the installation of the round head belt is according
to the Plate 20.

TS
I.2.2 The Track Lock. This is a knob on a shaft below the clutch
lever. To use turn the clutch lever vertical to disconnect the
drive and push the knob in until its shaft engages the track
gear. When it has engaged the gear, the carriage is prevented
from moving. It is used when it is required to use the sewing
head without the carriage moving.
1.2.3 The Crank Handle will adjust the angle of the head.
1.2.4 The OnlOff Switch turns the motor and needle cooling
(when fitted) on or off and should only be turned on when
the Knee Pad is fully pressed in.
2
PA
1.2.5 The Knee Pad, when fully pressed in, operates the motor clutch
electronically to stop the drive and applies a brake.
BEFORE SEWING
AT
The sewing head is usually supplied covered with a preservative oil. The
machine must be cleaned before use and lubricated as described in Para 7
Care should be taken to clean the upper and lower thread tensions and all
the thread guides to prevent faulty stitching.
2.1
TAPE GUIDE OR BINDER
Before attempting to close a mattress it is essential to check that the correct
binder has been fitted to suit the tape being used.
M
Cut the end of the tape at a slight angle to produce a point and feed it
through the binder. Turn the tape towards the needle to form a U shape
ready to embrace the edges to be joined. Check that the tape completely fills
the binder so that there is no sideways movement. If the tape is too narrow,
great difficulty will be experienced, because the binder will be unable to guide
an equal amount of tape on to the top and the bottom of the closed edge.
If there is variation in the tape width, it is better to be slightly oversize rather
than undersize.
Binders can be supplied to suit any width of tape, also with a standard or
wide mouth for the thicker tapes, such as are used on upholstery.
When ordering a new binder, it is essential to send a sample of the tape for
which it is intended to be used.
3
CORRECTLY MADE MATTRESS
3.1
TS
For maximum outpclt it is advisable to present the Tape-Edge machine
operator with a correctly asserr~bledmattress for closing, this has the
following characteristics:The materials should be accurately cut, so that the distance round
the edge of the panel equals the length of the border to which it is
to be joined.
R
A skilled operator can cope with small discrepancies between
these two lengths, but the job becomes more difficult and takes
longer, the greater the discrepancy.
AT
PA
The two edges of the material must be hemmed or overlocked
to prevent the tape-edge stitches pulling out of the weave
of the cloth. While an experienced tape-edge operator can
turn a hem in the top panel with his fingers as he closes the
mattress, the job is easier and can be done quicker, if both
the panel and the border are hemmed or overlocked on
separate sewing machines, before the tape-edge closing
operation.
The ends of the border material should be joined to form a
loop of accurately measured length and placed round the
mattress with the join in the middle of one end. Pack out
the corners equally with the loose filling material to form a
tight fit on the mattress.
If the top panel is loose, it should be secured by joining
its edges to the top edge of the border with upholstery
skewers, which can be easily removed progressively during
the closing operation.
M
3.3
If the top panel is a heavy quilted one, the upholstery of ,the
q ~ ~ ~ l tshould
i n g be attached to the spring unit by stapling
or hog-ringing before the border is put in place.
4
PREPARING TO CLOSE A MATTRESS
Using a good quality thread, thread the machine up as
described on Para 9.1
Put the reel of tape onto the tape pan and thread the tape
through the tensioner and into the binder, as described
in Para 2.1 above.
PA
R
TS
Lift the presser foot by means of the lever (0426 - Head Plate 5) and
pull about 15 cm. of tape through the binder and under the
presser foot.
Turn the Clutch Lever up and push the carriage round to
the middle of the end of the table. Turn the Clutch Lever
down to reconnect the drive.
Place the correctly prepared mattress on the table with
one end and one side about 2.5 cm. in from the edges
of the table.
It is usually considered best to start and stop the
tape-edge closing operation in the middle of the same
end of the mattress as the vertical join in the border.
Adjust the height of the sewing head so that the binder
is about 1 cm below the top edge of the border, and
adjust the angle of the sewing head to 45O (See Note B Para 5.1 1)
AT
Catch hold of the edge of the top panel with the thumb
and index finger of the left hand and catch hold of the
top edge of the border with the thumb and index finger
of the right hand. Bring these two edges together and
place them under the presser foot and in the middle
of the jaws of the tape binder. Holding the two edges
with the left hand, lower the presser foot lever.
M
Turn the sewing head Hand Wheel (top over towards you)
until the needle is fully down.
CLOSING A MATTRESS FOR THE FIRST TIME
Press the Knee Pad fully in and switch the motor on.
Catch hold of the edges of the panel and the border with
both hands, about 7 to 15 cm in front of the needle.
5.3
Slowly let the Knee Pad out until the carriage starts to
move towards you. Control the speed with the Knee
Pad and stop sewing about 2 cm short of your fingers.
5.4
Move both hands back 7 to 15 cms take another grip
and repeat the above operation.
TS
The correct action of ,the hands is to pull the two edges
up into the binder and away from the operator towards
the advancing sewing head. The inexperienced operator
will find this the opposite action to his instinctive desire
to pull the edges away from the advancing sewing head.
Pulling the edges away from the head can result in overriding the grip of the sewing head feed. dragging the
mattress along the table and bad taping.
Continue to sew short lengths until about 10 cm. short of
the corner, then stop and switch off the motor.
5.6
EXAMINE THE STITCHING
R
5.5
AT
PA
First check that there are no slip stitches. If there are, check
that the machine is correctly threaded and if the threads are
not tight enough, adjust the thread tensions. (See Para 10)
Then check that the tape has been satisfactorily stitched
to the mattress. The stitching should be from 1 to 2 mm in
from the edge of the tape. It is in too much, loosen the
two binder screws and move the binder in a little to the right
and away from the needle. Make sure the binder screws
are properly re-tightened or damage may be caused to the
binder.
M
If the stitching goes off the tape or is too near the edge,
loosen the binder screws and move the binder to the left
nearer the needle. Re-tighten the binder screws.
5.7
EXANllME THE TAPE
The fit of the tape in the binder should already have been checked.
If it is not correct, the indication that the tape is too narrow for the
binder is that the tape appears to roll round the edges of the
mattress and border, presenting too small a width on ei,ther the
top or bottom, so that the stitching runs off the edge of ,the tape
on one side only.
If a woven tape is being used. a certain amount of tension can be
applied by the tape tensioner. More tension can be obtained
by putting a weight on the reel of tape. Two sizes of weight are
supplied
Plastic and nylon tapes should have very little applied tension
The tape should stitch onto the mattress straight and even
with hardly any ripples.
If the tape is full of ripples (i.e. it looks as though the length of
the tape is greater than the length of the mattress edge to which
it is sewn), and the maximum tension is being applied, then the
stitch length needs reducing. (See Para 13)
TS
If the tape is very taut and the machine has a tendency to pull
the mattress along the table, first try reducing the tape
tension. If this is not enough, then the stitch length needs to be
increased.
Larger and thicker tapes tend to need a slightly longer stitch length.
Having checked the stitching and the tape, if both are correct the
beginner may attempt to sew round the corner. If they are not
correct it is advisable to go back to the start position, make the
necessary adjustments and try again.
PA
5.8
R
Larger tapes benefit by having their tension adjusted more by
the weight applied to tlie reel than in the tensioner.
To do this, pull some tape through the tensioner, swing the binder
forwards and cut the tape just in front of the presser foot.
AT
Turn the hand wheel over towards you until the needle is at its
lowest point, then turn the hand wheel in the reverse direction
until the needle is at its highest point.
M
Lift the presser foot lever and pull some slack thread through the
needle and looper tensions just where the threads disappear
into the machine. This will ensure that the threads will not break
and the machine will not need re-threading when the mattress is
pushed away from the sewing head. Push the mattress away from
the sewing head. Push the mattress away from the head and cut
the threads near the tape.
If more than one thread is seen coming out of the hole in the throat
plate, pull them all gently and the loose threads will come away
leaving the correct looper thread ready to start sewing again.
Turn the clutch lever up and push the carriage back to the start
position. Then unpick the sewing and remove the incorrectly
sewn tape.
mater~alat the edges. After passing round the corner, the
corner spring will return to its normal height.
After sewing round the corner, stop and look at the result
If the taped edge has a very pulled over appearance, as
though the length of the tape stitched onto the corner was
too short, the probable cause was the incorrect positioning
of the mattress in relation to the corner.
To correct this:
TS
Stop the motor,
Turn the hand wheel forwards until the needle is at its lowest
point
Turn the clutch lever up
Push only the carriage back 2 to 5 crns
Turn the clutch lever down
Press the knee pad fully in
Start the motor
Carry on sewing
R
..
..
..
.
AT
PA
The above condition should or~lyoccur occasionally.
If the pulled over appearance occurs at every corner, the
probable causes are one or more of the following:-
.
.
.
FINISHING OFF
Having sewn round four corners and four edges of one side of
the mattress, stop the machine just before where the taping
started and cut off the loose starting end of the tape flush with
the top of the inattress.
M
5.11
The tape tension is too great - reduce the weight on the tape
reel
The filler cord (if used) tension is too great - ensure sufficient
slack in the cord before taping round the corner
-The stitch length is too short - slightly increase the stitch length
Continue taping over the start by 5 to 7 crns.
There are two ways to finish,
Either, cut the tape just before it enters the binder and continue
to sew until you have sewn about 5 crns. passed the end of the
tape.
Or, pull a little tape through the tensioner, swing the binder
towards you and cut the tape between the binder and the
presser foot. Then fold the cut end under and slowly continue
to sew over the folded end and on for a further 5 cms. then :
PA
R
TS
Turn the motor off
Turn the hand wheel forward until the needle is in its lowest
position
Turn the hand wheel back until the needle is in its highest
position
Lift the presser foot lever
Pull some slack thread through both needle and looper
tensions just where the threads disappear into the machine
Push the mattress away from the head
Cut off the threads close to the taped edge
Clear any loose threads from the hole in the throat plate by
pulling gently until only the correct looper thread is left
If the above procedure is adopted, there will be no need to
re-thread the machine before starting to sew again.
Turn the mattress over and close the other side in the
same manner.
NOTE
It is advisable to keep the needle down whenever the machine
is stopped for any reason. This ensures that the material will
not slip out from under the presser foot and prevents a faulty
stitch at the stopping point.
AT
A)
There is no absolutely correct height'and angle for the sewing
head. They must be varied to suit the work and the operator's
preference. Many operators closing a tight mattress for
example, find it helps to adjust the height of the head as the
tightness increases while closing the mattress.
M

LUBRICATION
The sewing head has a semi-automatic lubricating system comprising a
hollow arm shaft and a hollow bed shaft, which act as oil reservoirs. The oil is
distributed to all of the principal bearings by centrifugal force through small
jets in the shafts when the machine is in operation. Provision is also made
for hand lubricating other movable parts which are not lubricated from the
reservoirs. Figs. 1-3.
6.1
OIL
BEFORE STARTING
TS
Recommended lubricant is TELESSO No:33, or SINGER types 'B' or 'Dl. Do
not use additives in sewing machine oil.
AT
PA
R
The machine must be oiled as instructed. Failure to do this may result in
damage to the machine.
6.4.1 TO OIL ARM SHAFT
To fill arm shaft reservoir, insert spout of pressure oil can in hole. Fig.4, and
inject 1 shot of oil into the shaft twice daily.
6.1.2 TO OIL BED SHAFT
To fill bed shaft reservoir, push spring cover, Fig.5, to the left, insert spout of
pressure oil can into hole and inject 1 shot of oil into the shaft twice daily.
Close oil hole spring cover.
Alternatively the bed shaft reservoir can be filled through the hole in the
middle of the driving pulley at the right hand end.
6.1.3 OTHER OILING POINTS
M
Apply oil to all work plate and arm oil holes, needle bar bearings and
connections, needle bar rock frame bearings, looper rocker sleeve and
presser lifting mechanism.
CAUTION
Machines in continuous use need to be oiled daily.

THREADING THE MACHINE
Turn the machine hand wheel over towards the operator as shown in Fig.6,
until the needle is at its highest point.
M
Pass the threads through all the threading points, as shown in Fig.6, and
draw approximately 50mm of thread through both the needle and looper eyes
to start sewing.
10
TENSION
The tension on the thread should be as light as possible but sufFicient to set
the stitch correctly.
IMPORTANT. Adjust the needle thread tension only when the presser foot is
down. because raising the presser foot automatically releases the needle
thread tension.
11
PRESSURE
The pressure on the material should be as light as possible, but sufficient to
ensure correct feeding.
To increase pressure, loosen the lower lock nut and loosen the lock screw
(if fitted) see Fig.8. then tighten the upper lock nut. When the correct
pressure is obtained, tighten the lock screw (if fitted), then tighten the lower
lock nut.
TS
To decrease pressure, loosen the upper lock nut and loosen the lock screw
(if fitted) then tighten the lower lock nut. When correct pressure is obtained,
tighten the lock screw (if fitted), then tighten the upper lock nut.

presser is at its highest. Then loosen the two clamp screws Fig.11, and turn
the lifting rock-shaft crank up or down until the desired lift of each presser is
obtained. Then tighten the two clamp screws.
CAUTION Limit the life of pressers to the minimum required for the work, as
this permits higher speeds.
PRESSER BAR 'TIMING
M
15
The walking (vibrating) presser should be timed so that under normal sewing
conditions, the presser foot will seat on the material at approximately the
same time as the needle enters the material. This timing can be advanced
or retarded slightly depending on the type of operation being performed, such
as sewing over seams.
To adjust, loosen the two holding screws, F i g . l l , not more than one half turn.
Then turn the adjustable eccentric Fig.?0,until the walking presser seats at
the correct time. Securely tighten the two holding screws after the adjustment
has been made.

When the loop deflector is positioned correctly on the underside of the feed
dog, there should be a clearar~ceof approximately 0.8 mm between it and
the right hand side of the needle, see Fig.15.
22
LOOPER SETTING
When the looper is correctly positioned, the point of the looper just clears the
scarf of the needle on the forward stroke of the looper and with the needle
rising.
To adjust turn the hand wheel until the point of the looper is directly opposite
the centre of the needle. Loosen the looper holder screw, Figs.16-17, and
tap the looper holder sideways until the correct clearance is obtained.
Tighten the looper holder screw.
TS
Move the looper to the extreme fotward position. Check the clearance
between the heel of the looper and the loop deflector. This should be
approximately 1.6 rnm. To adjust, loosen the two looper screws, and turn the
looper to the left or right until correct clearance is obtained. Securely tighten
the two looper screws. Then recheck the clearance of the looper point with
the scarf.
PA
R
When correctly set, the point of the iooper should be directly opposite the
centre of the needle and at the centre of the scarf when the looper timing
mark LT on the hand wheel is opposite the timing mark TM on the front of the
arm. See Figs. 6 & 16
To adjust the looper, loosen the looper carrier clamp nut Fig.17 and move
the carrier forward or backward until the point of the looper is directly
opposite the centre of the needle. Then tighten the clarr~pnut.
AT
To adjust the height of the needle so that the point of the looper passes the
centre of the scarf, first make certain that the needle is inserted as far as
possible into the needle bar and then loosen the needle bar clamp screws
Fig.18, and adjust the needle bar up or down. Then tighten the needle bar
clamp screws.
23
SETTING THE NEEDLE GUARD
M
When the needle guard is properly set, it should pass as close as possible to
the needle without touching. To adjust, turn the hand wheel over towards the
operator until the timing mark LT is 3.mm above the timing mark TM. Loosen
the needle guard screw, Fig.16, and turn the needle guard as close to the
needle without touching. Tighten the needle guard screw. Check by
springing the needle to the left and turning the hand wheel a complete
revolution to make sure that the point of the guard does not stroke the
needle.

TIMING LOOPER DRIVING CRANK
When the looper driving crank is properly timed, the point of the looper
should pass above the eye .of the needle at the same height on both the
forward and backward strokes of the looper Fig. 16.
AT
To adjust when the point of the looper passes higher on the forward stroke,
loosen the looper driving crank set screw, Fig.19. Loosen the looper crank
t~mingscrew (left) approximately 118th turn, and tighten the looper crank
timing screw (right). Continue to adjust until the correct setting is achieved.
Then securely tighten the set screw.

SPREADER SETTING
When .the looper on its forward stroke is passing the spreader
.
the point of the spreader should be exactly opposite the top of
the thread groove and to the left hand side of the looper Fig 20
the clearance between the spreader point and the looper
should be equal to two thicknesses of ordinary paper Fig 21
TS
To adjust loosen the two spreader holder set-screws, move the spreader to
the correct position and tighten the set-screws. The spreader should
however not touch the underside of the throat plate.
26
PA
R
When the point of the needle on it s downward stroke is level with the point of
the spreader, the clearance between the two points should be approximately
1.6 mm. To adjust, loosen the spreader screw and move the spreader
backwards or forwards to the correct position. Then tighten the spreader
screw. Fig.22.
CHANGING THE SPREADER MOVEMENT
AT
The sideways movement of the spreader can be adjusted, but under normal
conditions, the maximum spreader movement is generally used. To adjust,
turn the sewing head on it side and remove the base plate. Loosen the two
spreader driving eccentric screws and the two eccentric flange screws.
Fig.23. Then move the eccentric to the left to increase the movement or to
the right to decrease the movement. When correctly positioned, tighten the
two driving eccentric screws first, then hold the flange against the ball strap
and tighten the flange screws.
M
Caution, if the driving eccentric has been moved to the left, turn the machine
by hand to make sure the eccentric will clear the spreader driving rock shaft.
Then check the spreader setting.
27
ADJUSTING 'THE NEEDLE THREAD TAKE-UP
The needle thread take-up and thread guide may be adjusted to increase or
decrease the amount of thread drawn at the top of the needle bar stroke.
To increase the amount, loosen the thread take-up set screw, Fig.24, and
raise the take-up or loosen the guide screw and lower the thread guide. To
decrease the amount, reverse the adjustment by lowering the take-up or
raising the guide.
28
TS
For average sewing conditions, the guide should be set with the upper end
16 mm above the guide screw. The thread take-up should be set with the
lower end 13 mm below the bottom of its holder.
ADJUSTING NEEDLE THREAD TENSION RELEASER
29
PA
R
When correctly adjusted, the tension releaser should release tension on the
needle thread when ,the presser foot is raised and allow full adjusted tension
when presser foot is down. To adjust, loosen set screw, Fig.25, and move
tension releaser cap out for earlier release of tension or in for later release.
Hold in position and tighten set screw. Should the tension releaser not
release tension at the correct time after making the above adjustments,
loosen the tension releaser plate screw and move plate sidewise to correct
position. Then tighten screw.
ADJUSTING LOOPER THREAD TAKE-UP
M
AT
'The looper thread take-up and guide may be adjusted for handling more or
less thread, according to thickness of material and length of stitch, and
change the ratio of looper thread in the fir~ishedstitch.
To change the amount of thread handled, loosen looper thread guide screw,
Fig.26 and looper thread take-up rod screw. Move thread guide and take-up
rod to the left for more thread or to the I-ightfor less thread. Tighten the two
screws making certain that take-up rod passes through the centre of the
guide yoke.
To change ratio of looper thread in fir~ishedstitch, loosen thread guide screw,
Fig.26 and lower the yoke or right end of thread guide for more thread. For
less thread, raise end of guide. Hold in position and tighten guide screw.

SPECIAL OPTIONAL FEATURES
30.1
PIPING ATTACHMENT
(PLATE 2511)
A piping attachment is available, at an extra price, for the Model NR Tape
Edge Machine. It consists of a bracket for holding the 12 Ib. roll of roving,
guide piece to feed the roving into the needle, and a binder for using 1-7/16"
tape.
R
TS
This attachment produces the effect of a miniature roll edge, and adds height
to the box of the mattress. If the original machine is purchased with this
piping attachment, there is no problem for the user to figure out the feed of
the roving. The tape goes into the binder from the binder platen just as any
other tape would, and is hand-fed into the binder by cutting off the tape on
the bias to create a point for easier handling.
All machines are drilled in the factory for this piping attachment, so it can be
put on with the aid of an instruction drawing.
The piping attachment NR-465 is sold separately for later attaching.
PA
SPECIAL NOTE: When the piping attachment is used, we recommend
changing from a 30/3 to a 2413 cord thread on the needle.
Machines furnished with the piping attachment as original equipment also
have a standard 9/16" tape binder and pivot arm furnished as a separate unit.
The two binders with the'ir pivot arms are inter-changeable so that the
machine can be used for either 2 piping or a plain type.
AT
To change over from one attachment to another, sirr~plyremove the knurledhead pivot screw, replace the one attachment and its arm with the other, and
the machine is ready to sew. Of course, the different size tape (with or
without the roving) has to be fed into the binder. To do this quickly, cut the
tape on the bias with scissors to create a long (tapered) point, which will feed
into the binder easily.
M
30.2 EXTENSION RACKS - 0720
The special optional extension rack for oversize mattresses easily slides out
18" on either side to give extra support for King and other oversize
mattresses. Locks out of the way when working on standard size.
(see plate 18).
