Abstract

The presses or fly presses are those with >=2 manual controls (non-locking push button switches) which must be operated simultaneously to energise the various interlocked relays in the supply circuits to the electromagnetic distributors controlling operation of clutch and brakes by means of interlock connected auxiliary contacts. Each main relay is duplicated, with coils parallel connected, and key functions are supplied via the series connected main operate contacts of the pairs. Cam operated limit switches operate just before bottom lead centre and when the manual controls are released the punch is braked at top dead centre.
