Operating instructions

26. Long Trimmer for Looper Thread and Gimp (579-121000)

26.1 Cutting Pressure and Cutting Movement of the Looper and Gimp Thread Trimmer

Caution Risk of Injury!

Set the thread gripper and thread deflector only in the “Safe Stop”

position or with the machine turned off.

Rule and Control

The deflector 3 is mounted above the fixed knife 2. It prevents the

looper thread end and the gimp from lying between knife 2 and the

back of the thread catcher 7. Instead, they will both be guided next to

or into the thread catcher.

If this does not occur, the knife can be pushed away and doesn’t cut.

The cutting pressure can only be set so high as is necessary to

securely cut the threads.

The thread catcher must move past the thread grippers 5 as closely as

possible without the thread catcher touching the thread grippers.
