  • Patent number: 5419224
    Abstract: A device for the controlled removal of pieces of waste material is provided. The device has a non-rotatable cylinder shaft having an outer surface; a cylinder jacket having an inner surface and an outer surface and having at least one through-hole extending between the inner surface and the outer surface of the cylinder jacket, the cylinder jacket rotatable around the cylinder shaft; and sealing strips between the outer surface of the cylinder shaft and the inner surface of the cylinder jacket. The outer surface of the cylinder shaft, the inner surface of the cylinder jacket and the sealing means define a pressure chamber and a vacuum chamber, so that upon rotation of the cylinder jacket around the cylinder sleeve the at through-holes alternately connect with the pressure chamber and the vacuum chamber. The waste pieces are created when a pair of knives disposed on the outer surface of the cylinder jacket cut a moving web.

  • Patent number: 5407189
    Abstract: The invention provides a method and apparatus for continuous sheet delivery. According to the invention, a continuous stream of sheets is separated into a main pile, supported by a removable pallet, and an auxiliary pile, in which sheets are stored while the pallet and the main pile are removed and a new pallet is introduced. An embodiment of the invention includes a sheet supply, a pallet for accepting sheets from the sheet supply to form a main pile, a belt having a widened portion forming an edge for separating the edges of the pile to define an auxiliary pile, an auxiliary pile support, and a main pile. The auxiliary pile is divided from the main pile and supported separately therefrom by the dividing means while the pallet is replaced.
