A film cutter attachment includes one or more tape dispensing units, each of which dispenses automatically a continuous strip of pressure-sensitive adhesive transfer tape which is applied progressively to the back of a continuous strip of developed photographic film prints as the latter is drawn intermittantly into a conventional film cutter. Each tape strip is trained about a roller on the end of a pivotally movable arm which controls tension in the tape strip and causes additional tape to be dispensed. The film cutter cuts the print and tape strips after they are joined together adhesively into individual prints with adhesive transfer tape backing. The tape backing includes a cover ply which when peeled off leaves the strip adhesive adhered to the print and exposed for mounting the print.
Apparatus for dispensing a continuous strip of adhesive transfer tape composed of a transferable pressure sensitive adhesive layer and a releasable backing strip, for progressive application to the back of a continuous strip of photographic film prints as the latter is drawn intermittantly into a film cutter, the apparatus comprising:
In a film cutter including means for severing individual photographic film prints from a continuous strip of photographic film prints, indexing means for advancing intermittantly the photographic print strip to the severing means, and means for applying pressure to the photographic print strip, as it is advanced to the severing means, the improvement comprising:
Tape dispensing apparatus suitable for use with a photographic film cutter, said apparatus comprising:
In a photographic print cutting system, means for advancing a strip of photographic film prints, means for progressively applying two spaced apart pressure sensitive adhesive tape strips, each composed of a transferable pressure sensitive adhesive layer and a releasable backing strip, to the back face of the advancing print strip parallel to the length thereof, and means for simultaneously severing individual prints and portions of the tape strips applied thereto from the print and tape strips, respectively, to thereby provide individual photographic prints having pressure sensitive transfer tape backing made up of parallel severed portions of the two tape strips, said tape application means including dispensing means for dispensing the two tape strips from respective adhesive transfer tape rolls and for directing the tape strips into a course of travel aligned with the path of advance the print strip, and guide means providing an elongated path in said course of travel along which the tape strips are confined and maintained parallel in a single plane such that their adhesive layers and the back face of the print strip are progressively engaged in superimposed face to face relation as they are drawn conjointly to the severing means.
Tape dispensing apparatus, comprising:
