Variable width film splicer

Claim 2

A splicer, comprising: guide means for guiding strips along a run in end-to-end relation, said guide means including spaced apart edge guide elements adjustable to accept strips of different widths along said run; splicing means mounted adjacent said run for effecting a splice between adjacent strip ends, said splicing means including applicator means adjustable to apply different lengths of splicing tape between adjacent strip ends; and control means for controlling said guide means and said splicing means by adjusting said edge guide elements to accept strips of different widths, and adjusting said applicator means to apply different lengths of splicing tape in relation to the strip widths acceptable by said edge guide elements.

Claim 3

A splicer, comprising: guide means for guiding strips along a run in end-to-end relation; splicing means mounted adjacent said run for effecting a splice of selectively adjustable width between adjacent strip ends; and control means for controlling said guide means and said splicing means; said guide means including fixed edge guide means for engaging and guiding one strip edge, and moveable edge guide means for engaging and guiding the other strip edge; said splicing means including applicator means adjustable to apply different lengths of splicing tape between adjacent strip ends; said control means being operatively associated with said moveable edge guide means and said applicator means for selectively positioning said moveable edge guide means at selected positions spaced from said fixed edge guide means in order to provide edge guidance to strips of different widths, and adjusting said applicator means to apply different lengths of splicing tape which correspond, respectively, to the spacing of said moveable edge guide means from said fixed edge guide means in order to control splice width in relation to selected strip width.

Claim 4

A splicer, comprising: guide means for guiding strips along a run in end-to-end relation; splicing means mounted adjacent said run for effecting a splice of selectively adjustable width between adjacent strip ends; and control means for controlling said guide means and said splicing means; said guide means including fixed edge guide means for engaging and guiding one strip edge, and moveable edge guide means for engaging and guiding the other strip edge; said splicing means including applicator means adjustable to apply different lengths of splicing tape between adjacent strip ends; said control means being operatively associated with said moveable edge guide means and said applicator means for selectively positioning said moveable edge guide means at selected positions spaced from said fixed edge guide means in order to provide edge guidance to strips of different widths, and adjusting said applicator means to apply different lengths of splicing tape which correspond, respectively, to the spacing of said moveable edge guide means from said fixed edge guide means in order to control splice width in relation to selected strip width.

Claim 5

The splicer of claim 2, wherein said applicator means include means in overlying relation to said run for applying heat and pressure to selected areas thereof, and heat and pressure control means operatively associated with said heat and pressure application means for controlling the areas to which heat and pressure application are made.

Claim 6

The splicer of claim 3, wherein said heat and pressure application means include a plurality of heat and pressure application elements mounted for transverse movement to and from respective operative positions overlying discrete areas of said run, said heat and pressure control means being further operative for selectively positioning said elements at their operative positions in order to control the areas to which heat and pressure applications are made.

Claim 7

The splicer of claim 2, wherein said control means include means connected with said moveable edge guide means for moving said moveable edge guide means with respect to said fixed edge guide means, and means conjointly moveable with said moveable edge guide means for controlling the length of tape applied by said applicator means.

Claim 8

The splicer of claim 5, further comprising means for incrementally setting said control means such that said moveable edge guide means is positionable at multiple set positions with respect to said fixed edge guide means, and means for indicating the incremental settings of said control means.

Claim 9

The splicer of claim 2, further comprising means operatively associated with said guide means for positioning a strip at predetermined end-to-end spacing with an adjacent strip.

Claim 10

The splicer of claim 2, further comprising means operatively associated with said guide means for feeding spliced strips to an identification station, and then winding them into a roll.

Claim 11

The splicer of claim 8, further comprising means for sensing a strip and controlling said feeding and winding means.

Claim 12

The splicer of claim 2, wherein said moveable edge guide means include means for engaging the other strip edge at a plurality of spaced apart locations.

Claim 13

The splicer of claim 2, wherein said applicator means include a splice tape feed assembly which includes tape feeding means moveable reciprocatively along a path for feeding a length of splice tape into a position overlying adjacent strip ends, and wherein said control means include stop means conjointly moveable with said moveable edge guide means for establishing predetermined stop positions along the path of movement of said tape feed means at which said tape feed means may be engaged and prevented from moving farther along said path, thereby controlling the stroke of said tape feed means in order to control the length of tape applied.
