ABSTRACT:
An adhesive tape applicator includes one or more tape dispensing units, of which each dispenses a continuous strip of pressure-sensitive adhesive tape which is applied progressively to the back of a continuous strip of developed photographic film prints such that it does not become detached from the back of the print strip when the two are wound spirally into a roll. This roll thereafter can be unwound and severed, using conventional paper cutters, into individual prints with adhesive tape backing. The tape backing includes a cover ply which when peeled off leaves the strip adhesive exposed for mounting the print.
