Method and device for stacking sheet material

摘要

Process for stacking sheet material, especially sheets of paper or layers of sheets of paper, and for removing a stack (21) comprises introducing at least one first auxiliary stack support (28) in a first introduction direction below a sheet feed level (17) into a stack shaft (16), and lowering the first auxiliary stack support according to the increasing height of the partial stack forming on the support, whilst the finished stack resting on the main stack support (23) is lowered and removed from the main stack support. A second auxiliary stack support (36) is introduced from a starting position (40) below the sheet feed level in the opposite direction to the first introduction direction above the main stack support. The first auxiliary stack support is removed from the stack shaft in the opposite direction to the first introduction direction and the second auxiliary stack support is simultaneously introduced until the free ends of both auxiliary stack supports lie in a central region below the stack. The second auxiliary track support is removed from the shaft in the first introduction direction and in the opposite direction to the removal direction of the first auxiliary stack support. The auxiliary stack is placed on the main stack support. An Independent claim is also included for a device used for stacking sheet material.
