ABSTRACT:
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.
