Automatic changing of stacks of paper sheets for use in printing machine involves movable horizontal support surfaces sliding under part of stack, and two laterally-moving separating devices

摘要

The stack of paper sheets (1) is able to move downward (A). The top part of the stack (S) may be supported on two laterally-movable horizontal surfaces (2,3). The top part of the stack is restrained by vertical sidewalls (10,11), and separating members (4,5) may protrude at an angle through apertures in the sidewalls. Additional paper sheets (D) may be deposited on the top of the stack.
