Abstract: An apparatus for stacking sheets has a frame defining a stacking station and a pair of substantially parallel and transversely spaced guides on the frame in the station each having a horizontal lower edge and a planar inner face turned toward the other guide. Each guide is formed with a downwardly open notch opening at the respective lower edge and housing a respective guide plate vertically displaceable between a lower position projecting below the respective lower edge and an upper position wholly above the respective lower edge. Each guide plate has an inner face substantially coplanar with the inner face of the respective guide. A vertically displaceable platform is provided in the station underneath the guides along with a support rack horizontally displaceable in the station between an extended position directly above the platform and upwardly engaging the guide plates and a retracted position not directly above the platform and out of engagement with the guide plates.

Abstract: A diverter for paper and cardboard sheets has upper and lower guide elements between the incoming conveyor and two outgoing conveyors including an acute angle with one another, constructed so that the upper and lower guide elements are pivoted respectively about horizontal axes above and below the travel path and links are pivotally connected to these guide elements spaced from their pivot axes so that a four-point linkage of the guide elements is provided. The upper guide element is driven by a pivot drive and entrains the lower guide element via the links.

Abstract: A stacker for sheets, e.g. of cardboard or paper, is equipped with a device for inserting Marker strips or tabs within the stack to indicate predetermined numbers of sheets therein, e.g. for identification of reams. The inserter has a rigid channel Mounted on a frame moveable on a traverse transverse to the direction of sheet feed and the channel at its outlet is rigidly connected to a tongue having a substantially horizontal underside and moved with the outlet of the channel in a rectangular pattern with only vertical and horizontal path segments so that the tongue can be withdrawn from the stack without changing its orientation horizontally after a strip has been inserted into the gap formed by the tongue in the stack and alongside the tongue.

Abstract: A revolving cross cutter for material in web form comprises two driven knife drums, a transfer table following same in the line of transport of the web and a transport mechanism following the transfer table. The transfer table is mounted for yielding movement in the line of transporting comprising two vertical parallel flat leaf springs which are adjustably biased.
