Abstract
Apparatus and methods are provided for separating photographic film strips, adhered to a splice, by restricting movement of the splice and then pulling the film strips longitudinally in opposite directions. According to one feature, the splice adhesive is heated until it softens, preferably with a hot shoe applied against the splice under pressure. According to other features a space is left between the ends of the film strips when they are spliced together, and the splice is engaged from both sides while the film strips are pulled apart. Still more specifically, according to another aspect of the invention, a carrier or splice pick-up web is provided for removing the splices from the area and for holding the removed splices in a manner particularly convenient for disposal.
