Torque Limiter And Ratchet Wheel On The High-Speed Wheel - Duerkopp Adler 558 Service Instructions Manual

26. Torque Limiter and Ratchet Wheel on the High-speed Wheel

1
2
On the feeding shaft thereis a torque limiter.
It serves is avoid breakage through possibly jamming machine parts
(e.g. of the cutter bar if the cutting pressure is set too high).
The ratchet wheel 5 does not have a rigid connection to the
high-speed wheel 3. It can be turned against the pressure of a torque
rod up to a certain point. Only at this point does it begin to move with.
The handwheel can thus thus run first into the turn-off position (needle
high position) before the material support plate continues running in
quick transport.
