Abstract
A pad printing machine is disclosed in which the downward pressure forces are transferred to a thrust collar on the ink cup by application through a divided bearing which applies the hold-down forces at points that are spaced forward and rearward of the transverse pivot axis of the ink cup, and only at such spaced points, to resist rocking moments such as may arise from the reciprocating movements of the cliche. Further, the thrust collar is a combination of a very rigid pressure ring and a hard but slightly resilient plastic pressure distribution ring which is accurately machined after subassembly with the rigid ring to assure full mating engagement with the upper surface of the annular flange around the entire circumference of the ink cup, to assure uniform pressure of the entire knife edge on the cliche. In a preferred embodiment, the ink cup also is formed of a hard plastic.
