Abstract
Abstract A device for splicing photographic films together, especially suited for splicing together a number of films together to facilitate their passage through developing and fixing solutions. Each splice is formed with an adhesive tape which has a length longer than the width of the films so that the tape extends beyond each longitudinal edge of the films. The apparatus includes a roller having a pair of spaced flanges, one at each end thereof, the two flanges defining therebetween a groove of a width corresponding to the sum of the film width plus twice the thickness of the adhesive tape. The ends of each splicing tape are folded onto the opposite side of the film as the film passes around the flanged roller. A pair of pressing rollers are also provided to apply pressure to both sides of the splice to secure the folded end portions of the splicing tape.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
140 words
Apparatus for splicing two abutting sections of flexible material with a piece of tape adhered to and extending across said sections with each end of tape protruding from the longitudinal edges of said flexible material, said apparatus comprising a spool member having a pair of flanges defining a flat-bottom groove and being spaced apart a distance approximately corresponding to the sum of the width of the film being processed plus twice the thickness of the adhesive splicing tape, means for passing said flexible material with said tape adhered to the abutting end portions thereof over said spool in a manner to cause said protruding ends of said tape to be initially forced by said flanges into a position extending at right angles to said film, and then inwardly together by said spool as the abutting ends pass around said spool.
Claim 2
Dependent Claim
140 words
Apparatus for splicing two abutting sections of flexible material with a piece of tape adhered to and extending across said sections with each end of tape protruding from the longitudinal edges of said flexible material, said apparatus comprising a spool member having a pair of flanges defining a flat-bottom groove and being spaced apart a distance approximately corresponding to the sum of the width of the film being processed plus twice the thickness of the adhesive splicing tape, means for passing said flexible material with said tape adhered to the abutting end portions thereof over said spool in a manner to cause said protruding ends of said tape to be initially forced by said flanges into a position extending at right angles to said film, and then inwardly together by said spool as the abutting ends pass around said spool.
Claim 3
Dependent Claim
140 words
Apparatus for splicing two abutting sections of flexible material with a piece of tape adhered to and extending across said sections with each end of tape protruding from the longitudinal edges of said flexible material, said apparatus comprising a spool member having a pair of flanges defining a flat-bottom groove and being spaced apart a distance approximately corresponding to the sum of the width of the film being processed plus twice the thickness of the adhesive splicing tape, means for passing said flexible material with said tape adhered to the abutting end portions thereof over said spool in a manner to cause said protruding ends of said tape to be initially forced by said flanges into a position extending at right angles to said film, and then inwardly together by said spool as the abutting ends pass around said spool.
Claim 4
Dependent Claim
140 words
Apparatus for splicing two abutting sections of flexible material with a piece of tape adhered to and extending across said sections with each end of tape protruding from the longitudinal edges of said flexible material, said apparatus comprising a spool member having a pair of flanges defining a flat-bottom groove and being spaced apart a distance approximately corresponding to the sum of the width of the film being processed plus twice the thickness of the adhesive splicing tape, means for passing said flexible material with said tape adhered to the abutting end portions thereof over said spool in a manner to cause said protruding ends of said tape to be initially forced by said flanges into a position extending at right angles to said film, and then inwardly together by said spool as the abutting ends pass around said spool.
Claim 5
Dependent Claim
30 words
The apparatus of claim 1 additionally comprising a pair of rollers biased together which operate to press the folded ends of said splicing tape against a surface of said film.
Claim 6
Dependent Claim
