ABSTRACT:
The present invention employs a pneumatically driven front stopper which maintains multiple contact points with a sheet combined with a pneumatically driven push guide to position a sheet beneath an engraving press. An electrically driven sheet supply and plurality of drive belts bring sheets to the front stopper. A plurality of fans cause the imprinted portion of an engraved sheet to raise upwards, preventing smearing of wet ink, and encourage drying of the ink. The sheet feeder is driven by pneumatic actuators which are triggered by a cam assembly connected to the main drive shaft of the engraving press.
