Function of the trimming and clamping device for the needle
threads
The cylinder (1) is switched on following the seam end and during trans-
port to the corner knives. The thread-pulling knife (4) drops down and
picks up the needle threads.
The thread-pulling knife shoots up after a preset period of time.
The needle threads are clamped at the clamping plate (2) and cut off by
the knife (3).
The clamped needle threads are released after the first few stitches of the
next seam.
The elastic clamping plate (2) causes the thread-pulling knife (4) to abut
flat on the knife (3). This sets the knife automatically to the cutting position.
