Latest Patents

One of Ralf Zehl's latest patents is an "Apparatus for inserting a marker strip in a stack of sheets." This invention involves a stacker designed for sheets, such as cardboard or paper, which is equipped with a device for inserting marker strips or tabs within the stack. These markers help indicate predetermined numbers of sheets, facilitating the identification of reams. The inserter features a rigid channel mounted on a frame that moves transversely to the direction of sheet feed. At the outlet, the channel is connected to a tongue that moves in a rectangular pattern, allowing for the insertion of strips without altering the horizontal orientation of the tongue.

Another significant patent is the "Apparatus for stacking sheets." This invention includes a movable skid that senses the height of a pallet fed to a raisable and lowerable platform. The skid determines the pallet's height before it is fed to the platform of a sheet stacking apparatus. This innovation ensures that the position of the pallet below an intermediate stacking platform is accurately determined during pallet changes, preventing adverse effects from projections above the pallet's surface and avoiding excessive drops of the intermediate stack.
