  • Patent number: 5815787
    Abstract: A sheet stacking and lifting cassette tray assembly for reliably and effectively feeding sheets of different basis weight for use in a reproduction machine. The sheet stacking and lifting cassette tray assembly includes a cassette frame including a frame floor, and frame side walls; a plurality of sheet stacking and lifting subassemblies mounted within, and to, the frame side walls for applying selectable values of sheet lifting normal forces against a sheet feedhead. Each sheet stacking and lifting subassembly of the plurality of sheet stacking and lifting subassemblies includes a pivotable stacking and supporting plate, and a set of springs having a spring rate for providing a normal force having a particular value for lifting a stack of sheets.

  • Patent number: 4076411
    Abstract: Apparatus and method are provided for cyclically controlling the metering of photosensitive sheet material into an exposure station, cutting the material to a selected length, exposing the material to form a latent image thereon and advancing the sheet onto a rotating drum upon which the sheet is processed by the application of heat. To minimize the size of the apparatus and to reduce the time between exposures of successive prints the drum is made relatively small but rotated at a correspondingly higher rate with appropriate processing time provided by having each portion of the sheet remain on the drum for more than one revolution of the drum. Rotation of the drum is controlled by a counting mechanism to ensure that the drum has turned a sufficient number of revolutions to fully process the sheet and remove same from the apparatus. The apparatus also controls a stripper element so that this element is actuated at an appropriate time in a print cycle to remove the processed sheet from the drum.

    Date of Patent: February 28, 1978
    Assignee: Eastman Kodak Company
    Inventors: Bruce E. Crayton, James F. Wilson, Carl H. Zirngibl
  • Patent number: 3991955
    Abstract: A film threading device for use with cameras and/or projection devices is adapted to grasp the end of the outer convolution of a roll of film, tape or the like strip and guide it toward the film gate. In operation, first and second movable members, such as belts or pulleys, engage the periphery of the wound strip. The first movable member provides the film drive causing the wound film to rotate in an unwind direction. The second movable member provides a stripping action which drives the leading edge of the wound film away from a core and the film is guided by the moving member toward the nip of a thread pressure roller and a thread drive roller. The film is then guided to the film gate.
