Definitions

  • This invention relates to a mechanism for providing a predetermined amount of drag during the unwinding of tape from a cyclindrical core.
  • the invention also relates to a mechanism for providing two layers of tape under tension for the lamination of a toner image.
  • the strip being unwound is adhesive on one side, and is used to remove a toner image from a xeographic plate.
  • the strip must be adhesive enough to pull all or most of the developed toner image from the plate, but for that reason, will also tend to stick to the plate itself.
  • a drag force of 100 to 200 grams pulling back on the strip must be generated so that the plate may be removed from the strip after the transfer of the toner image, without pulling more material from the spool.
  • Any friction-producing means may be used to slow the motion of a spool, but most cannot be used in an image-producing process because of their tendency to produce dust. For instance, if a spring member is brought to bear on the spool, the contact point tends to wear, producing dust. A second consideration is shelf life and active life of the product. If a spool is rotably mounted on a shaft which is covered with a friction-producing material that will take a set, shrink or wear over a period of time, then the friction force produced will not be constant. Additionally, the covering material must be dust free. Finally, the drag mechanism must be low in cost.
  • the embodiment described herein comprises a plastic spindle covered with an open pore polyether-polyurethane foam layer which forms an interference fit with the inside diameter of the spool.
  • This material does not take a set, even when compressed for long periods, doesn't deteriorate over time, and doesn't wear to produce a residue or dust.
  • the foam itself, the plastic part on which it is attached, and the glue used to cement it, are all cheap and easily applied.
  • the tape 10 is supplied on a plastic core 11, the core having an inside surface that is substantially cylindrical and smooth.
  • this inner surface need not be manufactured to exacting standards since the foam roll 12 on which it fits will conform to slight irregularities.
  • the core 11 fits over the foam roll or strip 12 which is glued to a stationery spool 13 having notches 14 to mate with matching projections, not shown, to prevent spool rotation.
  • the foam roll 12 is made of polyether-polyurethane foam having sixty open pores per inch and a density of 1.2 pounds per cubic foot.
  • the foam roll 12 is bonded to the spool 13 by an adhesive or double face tape.
  • the adhesive may be Dow Corning Corporation's Part No. 8662 urethane bond.
  • the spool 13 is black polycarbonate.
  • Figure 2 shows the tape cartridge in which the invention is used.
  • a small xerqgraphic plate not shown, which has a developed toner image on its lower surface is driven in the direction of arrow 21 in contact with idler roller 22.
  • a transparent tape 23 having its adhesive side up.
  • the toner image will be transferred to the tape 23.
  • a translucent backing tape 24 is fed from a second roll mounted on an identical spool 13 with its associated foam roll 12. This backing tape 24 is pressed against the adhesive tape 23 at rollers 25 to form a laminated image.
  • Each roll of tape has a core 11 which rotates around the stationary spool 13 and foam strip 12.
  • the notches, not shown, of the spool 13 lock onto matching projections built into the case 25 which is made from medium impact styrene.
  • the case encloses the two rolls of tape and the spools, and constitutes an easily replaceable unit.
