Thread cutter
6.1
General
The large and the oversized hook could be used with the present
machine. In both cases the parts used are identical. The knife carrier
should only be mounted in a different position.
6.2
Position of the thread-pulling knife, position of the counter knife
Rule:
1. The counter knife (1) is to be screwed to the holder (2) with a 50 to
100 N force on the knife in the arrow direction (F).
This will avoid a change of the cutting pressure when loosening and
tightening the screw (4) of the clamp spring (3).
2. The holder (2) should be fixed with screw (5) to the hook bearing so
that the knives touch mutually at arrow point (6) during the knife
trimming motion. This guarantees an optimal cutting pressure.
ATTENTION !
If the pressure of the counter-knife is set too high this leads to an
excessive knife wear.
