<p>Mating abutting male and female locking projections depend from a die cutter blanket at opposite ends. The ends are received in an anvil channel having an arcuate corner surface. The anvil channel has a slot that receives a locking plate lip attached to the female projection in one embodiment to secure the female end. In the alternative, the projection and anvil channel have wedge shaped complementary portions and also may use replaceable strips. A blanket locking mechanism includes tandem primary and secondary air cylinders. The male blanket end has a locking recess that receives a locking mechanism nose. The nose simultaneously circumferentially and radially pulls the male end into the channel by operation of the primary cylinder. A locking bar is rotatably secured to the primary cylinder shaft and slidably rotates about an arcuate surface on a mounting base on the anvil and on an anvil coextensive arcuate surface as the primary cylinder shaft is lowered. The lowered shaft is friction locked with a spring/air operated piston of the secondary cylinder. The spring locks the primary shaft to permit the removal of pressurized air from the cylinders during operation.</p> |
