Abstract
Two conveyors for stacks of paper sheets are coupled to each other for movement back and forth between a first position in which one of the conveyors receives one or more stacks and the other conveyor is relieved of the stack or stacks thereon, and a second position in which the one conveyor is relieved of the stack or stacks thereon and the other conveyor receives one or more stacks. In order to expel air from the stacks on the conveyors the foremost portions of the stacks are clamped by reciprocable rams to the respective conveyors and the thus clamped stacks are caused to move along stationary squeegees which bear against successive increments of the stacks behind the respective rams while the stacks, the respective rams and the respective conveyors move away from the stack-receiving positions.
