5.1 Function
Caution: Risk of injury!
Switch the main switch off.
Check knife and thread catcher only with the sewing unit switched off.
Function
–
The cylinder 2 is switched on after the seam end and during the
feed to the corner knives.
The thread catcher 3 lowers and takes the needle threads up.
– After a preset time the thread catcher shoots up.
The needle threads are clamped at the clamping piece 1 and cut off
by knife 4.
– After the first stitches of the next seam the clamped needle threads
are released.
– By means of the springy clamping sheet 1 the thread catcher 3
abuts flat on the knife 4. Thus, the knife is automatically in parallel
position.
Function check
–
Call up the adjustment and test program “Selecting the output
elements” (see programming instructions chapter 5.6.1 Multitest).
– Select the output element “Y1”.
– Pull the needle threads to the back.
– Switch the output element on and off by pressing the function key
“OK”.
– Check whether the threads are accurately cut and clamped.
