Stack height determination and stack height control mechanism

Abstract

The invention concerns a stack height determination mechanism (25) for a stack (1) consisting of flat material (2), preferably sheet paper, with at least one sensor (3) to determine stack height and a stack height control mechanism with a stack height determination mechanism (25) of this kind. Exact determination of the stack height, especially in order to exactly position the stack for the next delivery of material (2), is achieved in that a flat element (4) to determine the height of the stack (1) is brought into a bearing position (5) on the stack and that this bearing position (5) is determined by at least one sensor (3).

Dependencies are inferred from the claim text.
