  • Patent number: 5060928
    Abstract: The invention relates to an apparatus for the depositing of sheets at a stacking location. The apparatus has an overhead suspension arrangement 15 which is fed with blasted air and extends some way over the stacking location 2, 3. This overhead suspension arrangement 15 has an undulating profile, extending in conveying direction, which imposes on the conveyed sheet to be deposited an undulation improving its dimensional rigidity, so that it can no longer buckle or turn on striking the stop. To reduce the conveying speed of the sheets, the stacking location is preceded by an overlapping station 9, 10, which initiates the braking operation a great distance ahead of the stacking location 2, 3 and keeps the sheet at braked speed almost until the striking of the sheet against the stop 6 without the overlapping being hindered by this.

  • Patent number: 4084806
    Abstract: A receiver member guide mechanism for a receiver member bearing a toned image, the mechanism including an open-wound helical spring wrapped tightly in a second helix around a support shaft. The shaft is positioned to locate the spring beneath the receiver member travel path. The shaft is rotated at a high rate of speed so that if a receiver member drops below the normal travel path, the lead edge of the member will be struck by the convolutions of the spring and redirected back into the travel path. The orientation of the convolutions of the spring is selected such that the peripheral surface of the convolutions provide only point contact with a receiver member so as to prevent smearing of the toned image.

  • Patent number: 4065839
    Abstract: A method and apparatus for the production of a stack of etched, patterned metal foils for component elements, such as fluid plates and nozzle plates, is disclosed. Individual patterned foils are cut free from a mat having a group of patterned foils and also edge foils. The patterned foils are examined and unwanted foils together with the edge foils are discarded. The approved foils are individually stacked at stacking positions in a stacking station. A number of foil stacks corresponds to the number of individual patterned foils in the mat with the patterned foils being placed on the foil stacks in correspondence with their arrangement in the mat. Additional patterned foils from additional mats are stacked onto the individual foil stacks until a counter for each of the stacks determines that a predetermined number of stacked foils has occurred. The stack is removed and a new stack is begun until the counter again arrives at the predetermined number of foils for a given stack.

  • Patent number: 4060235
    Abstract: In a copying apparatus in which copy sheets are stripped from a reusable imaging surface after the images have been transferred thereto, a vacuum stripping system is provided in which a pivotable, highly apertured, stripping head is normally closely spaced from the imaging surface and connected to a vacuum source to pneumatically capture the lead edge area of the copy sheet. The coverage of the vacuum apertures in the stripping head by the captured sheet pneumatically lifts the stripping head away from the imaging surface into alignment with a copy sheet transport, and shifts the stripping point of the body of the copy upstream on the imaging surface.
