(1) - Cylinder
(2) - Clamping plate
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 needle thread catcher (4) drops down and
picks up the needle threads.
The needle thread catcher 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 needle thread catcher (4) to abut
flat on the knife (3). This sets the knife automatically to the cutting position.
