Definitions

  • FIG. 3 is an enlarged fragmentary cross-sectional view of the pile fabric used in making the brush of FIG. 2;
  • FIG. 1 schematically illustrates a well-known xerographic process and apparatus for electrostatically photocopying documents.
  • Drum 10 is provided with permanent photoconductive layer 11 over its cylindrical surface.
  • the photoconductive layer 11 is commonly formed of selenium, and presents a relatively low electrical resistance when illuminated with light and a relatively high resistance whennot illuminated.
  • a plurality of operational stations are positioned about the periphery of the drum as follows: an optical station is provided at 14, for focusing an optical image on the photoconductor, a developing station is provided at 19, an image transfer station is provided at 24, a drum-cleaning station is located at 30, a general illuminating station is located at 31, and it is followed by a general charging station at 32.
  • the brush 27 After the image transfer operation, residual toner particles are removed from the surface of drum 10 by brush 27 at station 30. Then the photoconductive surface 1 l is exposed at 31 to uniform illumination by lamp 28. to erase any residual electrostatic image. Before returning to the optical exposure station, the surface of the photoconductor is exposed to a general corona discharge by electrode 29 at station 32, to provide a unifonn electrostatic charge over the photoconductive surface 11 and thereby enable electrostatic optical recording of an image of the document 13.
  • Brush 27, for cleaning residual toner particles from the selenium surface 11 of drum 10 is shown in the partial and enlarged perspective view of FIG. 2. As there shown, the brush comprises a cylindrical structurally rigid core 41, preferably formed of a suitable metal or other rigid material, such as a phenolic resin and glass fiber laminate.
  • a woven cut pile fabric 42 is secured over the cylindrical surface of the core 41, this fabric comprising a woven backing 43 carrying the pile fibers 44 interwoven therewith.
  • the woven backing 43 comprises warp and woof yarns 45 and 46, and woven into the backing is the pile yarn 47.
  • the pile yarn 47 is formed from very fine glass filaments
  • backing yams 45 and 46 are formed from thermoplastic resin filaments, such as polyethylene, polypropylene, nylon plastic, etc.
  • the glass fiber yarns 47 used to form the pile tufts 48 be formed from glass filaments having a diameter between about 3 microns and about l0 microns, and preferably about 4 microns, with between about and 450 filaments per yarn. Further, this pile fiber yarn should be woven into the fabric at a spacing that provides between I and 2 million, and preferably about 1% million pile fiber ends per square inch of pile fabric. The pile height should be between about 0.4 and 0.8 inch, and preferably about 0.6 inch.
  • a preferred backing yarn is polypropylene, but it will be apparent that the specific composition and diameter of the backing yarns are not at all critical to the practice of the present invention.
  • thermoplastic fibers fuse to said mandrel, whereby said mandrel becomes the core of said brush.
  • said backing yarns include fibers selected from the group of thermoplastic materials consisting of polyethylene, polypropylene, and nylon plastic.
