摘要
An offset blanket print/coat assembly for printing or coating rotating containers (14) has a blanket wheel (20) supporting a plurality of blanket assemblies (74,80) by means of radial frame plates (42,44) and an air cylinder (52) operable for retracting the blankets (B) inwardly on the blanket wheel (20). The blanket assemblies (74,80) move in both a radial direction (96) and an axial direction (94) in moving from a printing position to a stop-print position in response to the detection of the absence of a container (14) of a mandrel approaching the printing position. Novel inker blade adjustment means adjusts the fountain blade (FB) relative to the fountain roll (33) both inwardly and outwardly relative to the fountain roll (33) and holds the blade edge in various desired positions along its entire length by the adjustment of individual adjustment members (132) positioned along the blade length. A plastic seal (18) is urged from a slot (119) in each side plate (120,122) of an inker fountain against the end of the fountain roll (33) and provides a lightweight and secure liquid seal between the seal (118) and the fountain and also between the lower end of the seal (118) and the fountain blade (FB) to minimize ink leakage. The ink rolls (R2,R4,R6,R9) are cooled by lubricating oil pumped through them and then sprayed into the gear case (190) of the gears (G) driving the ink rolls (R2,R4,R6,R9) so as to cool the rolls and the gears (G) and provide required gear lubrication. Oil from the pump (P) of the gear cases (190) passes through a temperature control unit (198) for cooling the oil prior to the pumping of the oil back to the ink rolls (R2,R4,R6,R9).
