Abstract: A device stacks sheet-shaped materials (1, 1′) on a sheet stack with at least one deflecting element (82, 82′), mounted above the sheet stack and in the area of the leading edges (6, 6′) of the stacked sheet-shaped materials (1, 1′) so that it can rotate, and exhibiting at least one deflecting fin (83, 83′), whereby deflecting element (82, 82′) is driven and mounted so that it can rotate, whereby one deflecting fin (83, 83′) is in contact with the topmost sheet-shaped material (1) of the sheet stack that has already been stacked so that the leading edge (6′) of the next sheet-shaped material (1) to be stacked is deflected until the deflecting element (82, 82′), after stacking this next sheet-shaped material (1′), rotates far enough that a deflecting fin (83, 83′) is in contact with this sheet-shaped material (1′) that is now lying topmost.

Abstract: The invention relates to a devices and apparatus for processing of sheet-shaped print materials, for example cutting. An apparatus and process for on-the-fly cutting of sheet-shaped print material is provided wherein sheet-shaped print material is cut with a cutting device, an edge of said sheet-shaped print material is sensed upstream from the cutting device, and cutting of the sheet-shaped print material by the cutting device is initiated dependent upon a length of the sheet-shaped print material and the sensing of an edge.

Abstract: A fixing apparatus for electrostatographic reproduction or digital printing comprising: (a) a core (b) a gudgeon friction welded to said core, the gudgeon consisting of through slots or holes in a shoulder of said gudgeon.
