Abstract
Abstract An ultrasonic apparatus and method for forming individual pillowed chips of light lock material are provided. An ultrasonic horn and ultrasonic anvil are used to form pillows in a composite web of light lock material. The pillowed web material is then notched and cut to produce individual chips of light lock material. Each individual chip has one pillowed edge and one non-pillowed, notched edge. The pillowing and notching facilitate placement of the individual chips of light lock material into a film cartridge.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
185 words
An apparatus for forming individual chips of light lock material for placement in a cartridge, said apparatus comprising: a source of an elongated strip of light lock material, said strip having opposed edges; a machine frame; pillowing means mounted to said frame for forming transverse seams in said strip of light lock material, so that each seam is flanked on said strip by a pillowed profile in said light lock material; notching means mounted to said frame for cutting notches in said opposed edges between said transverse seams; cutting means mounted to said frame for cutting said strip of light lock material transversely at said transverse seams and transversely at said notches so as to form individual chips of light lock material, whereby each of said chips has a first transverse edge formed from a portion of one of said transverse seams next to said pillowed profile and a second transverse, straight-cut edge formed opposite said first edge; and positioning means mounted to said frame for moving said strip of light lock material from said pillowing means to said notching means and said cutting means.
Claim 2
Independent Claim
185 words
An apparatus for forming individual chips of light lock material for placement in a cartridge, said apparatus comprising: a source of an elongated strip of light lock material, said strip having opposed edges; a machine frame; pillowing means mounted to said frame for forming transverse seams in said strip of light lock material, so that each seam is flanked on said strip by a pillowed profile in said light lock material; notching means mounted to said frame for cutting notches in said opposed edges between said transverse seams; cutting means mounted to said frame for cutting said strip of light lock material transversely at said transverse seams and transversely at said notches so as to form individual chips of light lock material, whereby each of said chips has a first transverse edge formed from a portion of one of said transverse seams next to said pillowed profile and a second transverse, straight-cut edge formed opposite said first edge; and positioning means mounted to said frame for moving said strip of light lock material from said pillowing means to said notching means and said cutting means.
Claim 3
Dependent Claim
67 words
The apparatus of claim 1 wherein said pillowing means comprises: an ultrasonic horn engageable with one side of said light lock material for transmitting ultrasonic vibrations to said light lock material so as to compress said light lock material to form said transverse seams; and an ultrasonic anvil axially aligned with said ultrasonic horn and engageable with the other side of said strip of light lock material.
Claim 4
Dependent Claim
15 words
The apparatus of claim 1 wherein said notching means comprises a punch and die assembly.
Claim 5
Dependent Claim
15 words
The apparatus of claim 1 wherein said cutting means comprises a punch and die assembly.
Claim 6
Dependent Claim
61 words
The apparatus of claim 1 wherein said positioning means comprises a guide channel in which said strip of light lock material moves and shuttle clamps supported by said notching means which clamps pull said light lock material along in said guide channel, wherein said guide channel is aligned beneath each of said pillowing means, said notching means, and said cutting means.
Claim 7
Dependent Claim
17 words
The apparatus of claim 1 further comprising means for collecting said individual chips of light lock material.
Claim 8
Dependent Claim
39 words
The apparatus of claim 6 wherein said means for collecting comprises fingers to support one of said individual chips of light lock material and place said one of said individual chips of light lock material in a chip nest.
Claim 9
Dependent Claim
34 words
The apparatus of claim 7 wherein said chip nest is positioned on a conveyor to transport said chip nest to a cartridge into which said individual chip of light lock material will be placed.
Claim 10
Independent Claim
159 words
An apparatus for forming individual chips of light lock material for placement in a cartridge, said apparatus comprising: a source of an elongated strip of light lock material, said strip having opposed edges; a machine frame; pillowing means mounted to said frame for forming transverse seams in said strip of light lock material, so that each seam is flanked on said strip by a pillowed profile in said light lock material; cutting means mounted to said frame for cutting said light lock material transversely at and between said transverse seams so as to form individual chips of light lock material, whereby each of said chips has a first transverse edge formed from a portion of one of said transverse seams next to said pillowed profile and a second transverse, straight-cut edge formed opposite said first edge; and positioning means mounted to said frame for moving said strip of light lock material from said pillowing means to said cutting means.
