Tape Length when Sewing with the Light Barrier. Adler 745-23, 745-24, 745-22

3.11 Correcting the Corner Knives

This key calls up the correction function for the corner knives at the seam beginning (MA) and the seam end (ME).

The correction can be made for the sewing lengths L1, L2, L3 as well as for the light barrier seams LX (745-22;-23) and LX1, LX2 and LX3

(745-24).

– Press the function key.

The set values for MA and ME will be shown in the display.

– Increase or decrease the value for MA in steps by pressing the

"+/-" keys.

50 (no correction)

1 cycle = 0.085 mm

– Press the function key again.

This switches from MA to ME.

– Increase or decrease the value for ME in steps by pressing the

"+/-" keys.

– Complete the correction procedure by calling up the selected sewing length.

CAUTION !

With the 745-23 the corner knives must always be switched on or off together.

Set the parameters MA and ME at the median value 50.

Special note for 745-23:

When sewing with piping reverser only sewing length L1 can be set.

3.12 Tape Length when Sewing with Light Barrier

This key sets the tape length at the seam end when sewing with light barrier.

The set value corresponds to the distance from the initial position of the transport clasps to cutting.

– Switch on the tape feed.

– Press the function key.

The set value for the tape length is shown in the display.

– Increase or decrease the tape length in steps by pressing the

"+/-" keys.

4. Sewing of Bias Pocket Corners (745-24)

The bias pocket corners result from the offset between the left and the right seam row.

The desired seam offset is programmed separately at the control unit for the seam beginning (BR,BL) and the seam end (ER,EL).

If all parameters are set to the median value "10", then a straight pocket results.

Parameters for the programming of the bias pocket corners:

Seam beginning

1 ... 10 ... 20

Right seam

Left seam

1 ... 10 ... 20

BL

Seam end

ER

Selected sewing distance

Programming the bias of the pocket corners:

– Simultaneously press the key for the desired sewing distance (L1,

L2 or L3) and the " " key.

– For selecting a light barrier seam:

Press the " " key until the desired light barrier seam LX1, LX2 or LX3 appears in the display.

Simultaneously press the " " and the " " keys.

– The parameters for the programmed bias of the selected sewing distance appear in the display (see display example).

– Increase or decrease the parameter values in steps by pressing the "+/-" keys.

Minimum: 1

Maximum:20

Median value: 10 (straight pocket corner)

Steps: 1 step = 1 stitch of the current stitch condensation

Attention!

The left and right seam rows must always be offset an equal number of stitches with reference to the median value "10".

The parameters BR and BL to be set for the desired seam offset can be found in the table on page 14.

The parameters ER and EL are arrived at in the same manner.

– Press the "

Σ

" key.

The cursor moves to the next parameter.

– Complete the setting procedure by pressing the key for the selected sewing distance L1, L2, L3 or the " " key (for light barrier seams).

ATTENTION !

With bias pockets the following additional setting work must be conducted:

– Manually adjust the angle and height of the corner knives according to the programmed seam offset (see Operating

Instructions) or:

Switch the corner knives off via the " " key on the controlunit.
