Patent number: 6499524Abstract: A dispenser for applying a material to a surface includes a supply spool rotatable about an axis, a quantity of unused tape stored on the supply spool, and an applicator head about which the tape is passed. The head presses the tape against a surface to deposit a transfer layer of the tape onto the surface. A take-up spool stores a backing layer of the tape after the transfer layer has been deposited on the surface. The take-up spool is also rotatable about the axis. A housing surrounds at least a majority of the tape, a substantial portion of the housing being substantially cylindrical in shape. The tape is guided from the supply spool to the head and from the head to the take-up spool. The applicator head is located substantially along the axis, and the spools are movable along the axis. The tape causes movement of the spools along the axis as the spools are rotated about the axis. The-tape is stored on each spool in a plurality of tape layers thick and a plurality of tape widths wide.Type: GrantFiled: September 7, 1999Date of Patent: December 31, 2002Assignee: Berol CorporationInventors: Crispin M.
