ABSTRACT:
The present invention relates to a safety mechanism for a multiphase forming machine, in which trigger signalling is used to automatically stop the machine by means of the insulation state formed between one leg of a clamp and a stock conveyor to which the clamp is attached as well as whether a nut stock is firmly held by the clamp so as to prevent any part of the machine from being damaged or destroyed.
