An automatic adaptation of the looper thread quantity to the stitch
length allows an optimum stitch formation in every stitch length,
even with balloon stitch.
Designated use
Class 175/176/179 is a sewing machine head determined for
processing light to medium-weight material, i.e. fabrics made of textile
fibers or leather. Such sewing materials are used in the clothing
industry and for the production of home upholstery.
Furthermore, this sewing machine head can also sew so-called
technical seams. However, in this case the user has to estimate the
possible risks (preferably in cooperation with DÜRKOPP ADLER AG)
because on the one hand such fields of application are comparatively
rare and on the other hand there is an immense variety of application
possibilities. According to the result of this estimation suitable safety
measures may have to be taken.
5
GB
Generally only dry fabrics must be processed on this sewing machine
head. The material must not be thicker than 4 mm when compressed
by the lowered sewing feet. It must not include any hard objects
because otherwise the sewing machine head would be allowed to be
operated with an additional eye protection only. Such an eye
protection cannot be delivered at present.
In general the seam is produced with sewing threads made of textile
fibers up to 70/3 Nm (core thread). If other threads are to be used, it is
indispensable also in this case to consider the possible risks and to
take corresponding safety measures, if necessary.
The sewing machine may be set up and operated only
in dry, well-maintained premises. If the sewing machine is used in
premises which are not dry and well-maintained it may be
necessary to take further precautions (which should be agreed in
advance - see EN 60204-31:1999).
As manufacturers of industrial sewing machines we proceed on the
assumption that personnel who work on our products will have
received training at least sufficient to acquaint them with all normal
operations and with any hazards which these may involve.

Adjusting the needle thread tension
The needle thread tension has to be tighter than that of the looper
thread.
Increase the needle thread tension: Turn setting wheel 1 clockwise.
Reduce the needle thread tension: Turn setting wheel 1 counter-clockwise.
Too tight thread tensions cause puckering of the material.
A too loose looper thread tension may lead to skipped stitches.

6.4
Needle thread quantity for safe stitch formation
In case of elastic sewing threads, e.g. synthetic fibre threads or
monofilament threads, a certain needle thread quantity must be pulled
to guarantee a safe stitch formation.
This is done in thread lever position “down” in conjunction with the
thread regulator 2.
Adjust the thread regulator in position “down” of the thread lever 4 as
follows:
In case of elastic sewing threads the lower thread bore is visible.
Thread the needle thread past the bow 3 on the left (see fig. a).
In case of less elastic sewing threads, as e.g. cotton, the upper thread
bore is visible. Thread the needle thread past the bow 3 on the right
(see fig. b).

Adjusting the looper thread feeder (Cl. 175/176)
The looper thread feeder 1 guarantees the automatic adaptation of the
looper thread quantity to the set stitch length.
This means an optimum stitch formation for every stitch length, even
in case of condensed stitches. No gaping and ruffling of the seam.
The looper thread quantity to be pulled can be quickly adjusted.
Without changing the thread tensions you can realize:
a) tight
a)
b) normal
b)
c) highly elastic (balloon stitch)

After loosening the screws 2 and adjusting the feeder 1 please make
the following settings:
– Loosen screws 2.
– Adjust the thread feeder:
towards 0 = tighter seam
towards 5 = more elastic seam
Important hints!
1) In case of an extreme adjustment, e.g. a very short stitch length and
a very large thread quantity (elastic seam) it has to be observed that a
safe needle penetration into the thread triangle is still possible. A too
large looper thread quantity may lead to skipped stitches.
2) If the stitch length is increased considerably with the settings
described under 1), e.g. to 4 mm, the thread guide has to be reset
towards 0. Otherwise the looper thread might jump off the thread
pick-up disc. The looper thread would not be pulled back by the
thread pick-up disc as it is necessary during the retrograde motion of
the looper.
