3.7 Adjustments of the bobbin threat

catcher (Beisler sewing head)

3.7.1 Catcher adjustment

Turn the belt disk manually until the spool capsule lever

stands as far as possible back into arrow direction. Fix

the movable knife (4) temporarily with the screw (3) and

press manually onto the top side of the knife (4) to move

it. Tighten screw (3) when the distance between the top

of the movable knife to the holder of the catcher is net-

ween 0.05 and 0.2 mm.

Fix the movable knife (4) at the top of the spool clamp

spring now.

3.7.2 Time of bobbin threat cutting

This time can be programmed.

If the time is too early, upper and bobbin threat will be

caught and cut at the same time. Then the upper threats

will be too short for the next sewing process.

3.7.3 Duration of bobbin threat cutting

This time can be programmed.

If the time is too short, the bobbin threats will not get

caught. If the time is too long it is possible that the main

clamp drives to the mitre cutting before the threat cat-

cher is in cutting position. This lengthens both threats

remaining at the seam end.

3.8 Sensitivity of the bobbin detector

(option)

Insert full bobbins into the grasper and close the sliding

plate. Activate the bobbin detector.

Open the casing of the switchboard and turn the poten-

tiometer (2) to the left until the LED (1) lights up. Now

turn the potentiometer (2) as far to the right until the LED

doesn’t light up during the sewing. Mount the casing of

the switchboard.

Occupation of the LEDs and potentiometers:

(1) (3) right-handed spool

(2) (4) left-handed spool

Hint

During sewing with residual threat on the spool, the

LED (1) (2) must switch several times per rev.
