  • Patent number: 6182962
    Abstract: In an apparatus for separating sheet material from a stack, the latter rests on a movable pressure plate, by adapted to feed the stack to a withdrawal device. The pressure under which the stack is urged against the withdrawal device is dependent upon the density of the stack. For determining the density, the apparatus comprises a density sensor which determines the density of the stack continuously during the separation process at least in the region of the withdrawal device.

  • Patent number: 5803446
    Abstract: A method for singling loose sheet material, in particular bank notes, wherein the sheet material is supplied in an input pocket in the form of a stack in a defined position for vertical feed of the sheet material to a singler. The sheet material is moved within the input pocket vertically from the feed position to a singling position. While the preceding stack is still being singled in the singler, the next stack to be singled is already supplied in the input pocket of the singler in the defined feed position.

  • Patent number: 5039020
    Abstract: The invention relates to a method and apparatus for monitoring the destruction of thin sheet material, in particular bank notes, in an automatic sorting machine, whereby the sheet material is fed by a transport means successively sheet by sheet to a motor-driven cutting means having meshing cutter boards. The destruction process and/or its immediate result are detected by sensor means.

  • Patent number: 4878626
    Abstract: In a high-speed sorter, single documents such as banknotes are successively withdrawn from a stack and tested according to various criteria. Banknotes which are authentic but no longer fit for circulation are fed to a cutting means a shredder and destroyed therein. The shredder, which has a simple construction and is designed for a high banknote throughput, consists of two cutter blocks including overlapping cutter discs which work into one another with little play in spaced relationship and are provided along their periphery with notches, and which slit and crosscut the banknotes. A suction plant prevents back-ups from forming, cleans and cools the cutting means.

  • Patent number: 4568137
    Abstract: An electrical connector has an arrangement for holding and connecting at least one fuse cartridge within the body of the connector, the arrangement including a fuse cartridge holder slideably received within a recess in the connector body, in a rectilinear manner, and secured in place in the connector body by a selectively disengageable latch mechanism.

  • Patent number: 4553312
    Abstract: A device for removing a band (2) wrapped around a bundle (1) of sheets by means of a cutting device (11). The cutter (7) of the cutting device is arranged on the plane on which the bundle is transported in such a way that it dips into a side face of the bundle, cutting along the entire length of the bundle and thereby severing the band located at right angles to the side face. The severed band (2) is grasped on the side opposite the cutting by a hook (13) of a pull-off device (12) provided opposite the cutting device (11), and removed at right angles to the direction in which the bundle (1) is transported.

  • Patent number: 4522387
    Abstract: A device for stacking sheets comprises several disks arranged adjacent to each other on a driving shaft, the disks having spiral slots running from the outside towards the inside. The spiral slots of the disks overlap in an axial direction and together form a pocket into which the sheets conveyed. In order to guarantee trouble-free stacking of the sheets, the spiral slots of adjacent disks are staggered at least in the inner area of the stacker. Therefore, almost all the kinetic energy of a sheet which is inserted into the shot is issipated by frictional and flexing. The spiral slots of one or more disks may additionally be provided with elastic boundary walls.

  • Patent number: 4466605
    Abstract: A stacking device for sheet material such as banknotes and receipts has a stacker drum with a suction opening at a predetermined location on the periphery. The suction opening grips the leading edges of the sheets to be stacked at a first tangential position and releases the sheets against a stopper at a second tangential position. The stacker drum has air openings on the periphery behind the suction opening. The air openings discharge pulsating compressed air to separate the portion of the sheets trailing the leading edges from the drum.
