Abstract The present invention relates to an improvement in an automatic adhesive tape feeding device for a photographic film splicing apparatus for bringing the tail end of one film into alignment with the lead end of another prior to or after development. The device includes an adhesive tape drawing means having, in combination, a first rotatable roller and a second or draw-out roller resiliently contacting the former and provided, on its circumferential surface facing the adhesive side of the tape, with a plurality of saw-teeth made of an adhesion-resistant material such as TEFLON; and an adhesive tape feeding means having, in combination, a pair of feed rolls of which one roll has a conical-convex circumferential surface and the other roll has a conical-concave circumferential surface lined with a nonadhesive material such as TEFLON. The feed rolls are characterized in that they serve to feed an adhesive splicing tape from its supply roll to a film connecting position without sticking to either feed roll and in that the tip of the tape is formed into a V-shaped configuration to prevent the tape from hanging down after it passes through the feeding means.
AN APPARATUS FOR SPLICING TWO SECTIONS OF FLEXIBLE MATERIAL COMPRISING: MEANS FOR ALIGNING AND ABUTTING AN END OF A FIRST SECTION WITH AN END OF A SECOND SECTION, MEANS FOR FEEDING A LENGTH OF ADHESIVE SPLICING TAPE TO A POSITION ADJACENT SAID ENDS, SAID FEEDING MEANS COMPRISING MEANS FOR BENDING THE TAPE ALONG A LONGITUDINAL AXIS OF THE TAPE INTO A V-SHAPED CONFIGURATION, SAID BENDING MEANS COMPRISING FIRST AND SECOND ROLLER MEMBERS ENGAGING SAID TAPE, SAID FIRST ROLLER MEMBER HAVING A FRUSTOCONICAL-CONCAVE CIRCUMFERENTIAL SURFACE AND SAID SECOND ROLLER MEMBER HAVING A CONICAL-CONVEX CIRCUMFERENTIAL SURFACE, THE CIRCUMFERENTIAL SURFACE OF SAID FIRST ROLLER MEMBER BEING INTERMESHED WITH THE CIRCUMFERENTIAL SURFACE OF SAID SECOND ROLLER MEMBER TO PROVIDE FOR CONTACT BETWEEN THE SPLICING TAPE AND SAID FRUSTOCONICAL-CONCAVE CIRCUMFERENTIAL SURFACE ONLY ALONG A CENTRAL LINE OF SAID FRUSTOCONICAL-CONCAVE SURFACE, AND MEANS FOR FLATTENING AND PRESSING SAID TAPE INTO INTIMATE CONTACT WITH SAID ENDS.
