7.13 Needle thread catcher
When sewing without a stitch chain, that is, by slits
or seam interruptions, the bobbin and needle
threads are drawn after by a certain amount. The
thread trimmer then cuts off both threads. The
bobbin thread is held clamped by the trimmer and
the needle thread by the thread catcher 6.
To catch the needle thread the thread catcher
should be open as far as possible. The moving
leg_7 must, however, not bump into the material
guide rail. This applies particularly to curved rails
with small radii. The distance at the nearest
position should be about 1 mm.
– Turn main switch off.
– Enter Program 64 and activate with the STOP
key.
– Key in the code no. 7 for the solenoid valve s7
"Open Thread Catcher". The thread catcher can
be opened and closed with the
Σ
key.
– To check the clearance the rail must be run
along the open thread catcher manually. This is
only possible with the main switch on when the
fuse 8 of the step motor controls has been
removed.
– Loosen screw 9. Set the leg 7 at a distance of
approx. 1 mm at the tightest point of the rail.
– This clearance is to be checked with all rails
employed.
