Abstract
Abstract In a pre-process film splicing arrangement a novel filmstrip handling apparatus for presenting a filmstrip to a splicing station in accurate orientation to the tail end of a previously spliced filmstrip to insure a secure splice while maintaining integrity of the filmstrip perforation spacing. The handling apparatus accomplishes both accurate positioning and trimming of the lead and tail ends of the filmstrip, and includes a slack take-up arrangement whereby the end trimming steps can be accomplished at proper timed intervals without discontinuing filmstrip movement along its entire length during any particular cutting operation in order to provide high speed operation.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
213 words
In an apparatus for successively moving a series of strips to and past a splicing station wherein the lead end of each strip is adapted to be spliced to the tail end of a preceding strip, a guideway for guiding said strips during such movement comprising: a base; a segmented guide track supported by said base, said guide track having, in order, an entrance section, a mid-section, and an exit section, the junction between said mid-section and said exit section being located at said splice station; said entrance section having drive means for selectively advancing successive strips along said segmented track to said splice station; said mid-section being selectively pivotable about an axis between a first position out of alignment with said exit section and a second position in alignment therewith, said axis being located perpendicular to the forward direction of travel of said strip in said entrance section to maintain the continuity of the travel path of said strip between said entrance section and said mid-section; means for pivoting said mid-section about said axis; and means operable as said mid-section is pivoted from said first position to said second position for trimming the lead end of a strip in said mid-section to prepare said lead end for splicing in said splice station.

In an apparatus for successively moving a series of strips to and past a splicing station wherein the lead end of each strip is adapted to be spliced to the tail end of a preceding strip, a guideway for guiding said strips during such movement comprising: a base; a segmented guide track supported by said base, said guide track having, in order, an entrance section, a mid-section, and an exit section, the junction between said mid-section and said exit section being located at said splice station; said entrance section having drive means for selectively advancing successive strips along said segmented track to said splice station; said mid-section being selectively pivotable about an axis between a first position out of alignment with said exit section and a second position in alignment therewith, said axis being located perpendicular to the forward direction of travel of said strip in said entrance section to maintain the continuity of the travel path of said strip between said entrance section and said mid-section; means for pivoting said mid-section about said axis; and means operable as said mid-section is pivoted from said first position to said second position for trimming the lead end of a strip in said mid-section to prepare said lead end for splicing in said splice station.
Claim 3
Dependent Claim
20 words
The apparatus of claim 1 wherein said trimming means includes cooperating cutter blades on said mid-section and said exit section.
Claim 4
Dependent Claim
55 words
The apparatus of claim 1, wherein said mid-section is supported from said base by a pivot means adjacent that end of said mid-section nearest said entrance section and is swingable about said pivot means between said first and second positions so as to always maintain a travel path between said entrance section and said mid-section.
Claim 5
Dependent Claim
84 words
The apparatus of claim 1, the strip being of the type having regularly spaced perforations along one edge thereof, and said apparatus further comprising means associated with said entrance section for trimming the tail end of a strip in predetermined relation to its perforations; and means responsive to the approach of a trimmed tail end of a strip to said splicing station for accurately locating said trimmed tail end in proper position in said splicing station for splicing therein to the next succeeding strip.
Claim 6
Dependent Claim
42 words
The apparatus of claim 1, wherein said mid-section further includes slack take-up means ahead of said splice station to provide for accumulation of at least a portion of a strip while the lead end of said strip is in said splice station.
Claim 7
Dependent Claim
51 words
The apparatus of claim 5, wherein said slack take-up means includes a trap door carried by said guide track mid-section, a slack box located beneath said trap door, and an actuating means operable to selectively open said trap door to provide for accumulation of said strip portion in said slack box.
Claim 8
Dependent Claim
47 words
The apparatus of claim 1, wherein said trimming means includes sensing means associated with said mid-section for detecting the presence of a strip therein, and means responsive to said sensing means for locating the lead end of said strip in a predetermined position relative to said mid-section.
Claim 9
Dependent Claim
17 words
The apparatus of claim 7, wherein said pivoting means is responsive to actuation of said locating means.
Claim 10
Dependent Claim
62 words
The apparatus of claim 7, the strips being of the type having regularly spaced perforations along one edge thereof, and wherein said locating means includes a registry pin movably mounted on said mid-section and adapted to be selectively movable to intersect said guide track to engage one of said perforations, and means responsive to said sensing means for actuating said registry pin.
Claim 11
Dependent Claim
39 words
The apparatus of claim 7 further comprising means responsive to said sensing means for locating the tail end of a strip in proper position in said splicing station for splicing to the lead end of the next succeeding strip.
Claim 12
Dependent Claim
36 words
The apparatus of claim 7 further comprising slack take-up means responsive to actuation of said locating means for accumulation of the trailing portion of said strip while the lead end is located in said predetermined position.
