Abstract:
An apparatus for automatic bundling of sheet material, comprising a deposit device (20) on which sheet material (10) to be bundled is deposited as a precisely fitting stack, a sliding device (21) moving the stack of sheets perpendicularly toward a foil (40) supported by a foil device, the stack (10) having a height and being partly wrapped with the foil (40) and fed onto a transport device including upper and lower conveyer belts (50, 60) disposed parallel to each other and one above the other for positioning the stack relative to a banding device (34, 35) such that the foil (40) is guided around the back end of the stack (10) by the banding device (34, 35) and connected into a band (41), thereby obtaining a bundled stack of sheets (11), wherein the deposit device (20) is lifting table vertically adjusted to a predetermined vertical position according to the stack height, and the lower conveyor belt (60) is vertically adjusted automatically to the vertical position so as to produce a continuous channel between the lifting table (20) and the lower conveyor belt (60) thereby clamping the stack partly wrapped with foil between the conveyor belts (50, 60).
