Abstract
A method and apparatus for handling a stack of sheets, including the stacking of the sheets from a continuous incoming stream of sheets and on a lower endboard, and compressing the stack and restricting the sides of the stack while the stack is moved laterally to a station where an upper endboard is applied and the stack is strapped or bound and then moved further away.
Claims12
A method of handling a stack of sheets, comprising the steps of collecting the sheets into an inclined upright stack on its back on a stacker and on a first endboard, compressing the stack along its length and moving the stack sidewise off the stacker and while the stack is still compressed, supporting the stack and releasing stack compression and then placing a second endboard at the top of the stack while the stack is off the stacker, pressing the second endboard downwardly onto the stack, and again compressing the stack while binding the stack.
Apparatus for handling a stack of sheets formed from a stream of sheets, comprising a stacker for stacking the sheets in an upright stacked relation and on an endboard, side members adjacent said stacker and movable toward and away from the respective sides of the stack for abutting the stack sides, a compression member mounted on said side members and movable downwardly onto the stack for compressing the stack for compressing the stack onto said endboard, stack support means extending away from said stacker, powered means connected to said side members for moving said side members and the stack sidewise on said stack support means and to a position offset to one side of the stacker, means connected with said compression member for moving said compression member off the stack, an endboard inserter offset to the one side of said stacker for positioning an endboard on the top of the stack, a compressor offset to the one side of said stacker and operative on the stack for again compressing the stack and thereby forcing said endboards toward each other, and a strapper offset to the one side of said stacker for binding the stack while the stack is being compressed.
