Abstract
Abstract An apparatus and method for feeding, cutting and substantially simultaneously applying strip solder material to an assembly comprising a plurality of workpieces preliminary to soldering the workpieces to another member in which there are provided means for retaining the workpieces in predetermined positions relative to each other, feeding the strip solder material into simultaneous contact with adjacent corresponding surfaces of the workpieces, cutting the strip material to provide a cut strip of predetermined length sufficient for this simultaneous contact and shaping means for bending the cut strip at the ends of the cut strip into wrap-around gripping engagement with the sides of the assembly of workpieces.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
104 words
Apparatus for feeding, cutting and substantially simultaneously applying strip solder material to an assembly comprising a plurality of workpieces preliminary to soldering the workpieces to another member, comprising: retaining means for retaining said workpieces in predetermined positions relative to each other; feeding means for feeding said strip solder material into simultaneous contact with adjacent corresponding surfaces of said workpieces; cutting means for cutting said strip material to provide a cut strip of predetermined length sufficient for said simultaneous contact; and shaping means for bending the said cut strip at the ends thereof into wrap-around gripping engagement with the sides of said assembly of workpieces.
Claim 2
Dependent Claim
104 words
Apparatus for feeding, cutting and substantially simultaneously applying strip solder material to an assembly comprising a plurality of workpieces preliminary to soldering the workpieces to another member, comprising: retaining means for retaining said workpieces in predetermined positions relative to each other; feeding means for feeding said strip solder material into simultaneous contact with adjacent corresponding surfaces of said workpieces; cutting means for cutting said strip material to provide a cut strip of predetermined length sufficient for said simultaneous contact; and shaping means for bending the said cut strip at the ends thereof into wrap-around gripping engagement with the sides of said assembly of workpieces.
Claim 3
Dependent Claim
34 words
The apparatus of claim 1 wherein said means for retaining comprises a base having means thereon spaced similarly to said workpieces in said assembly for engaging said workpieces and retaining them in fixed position.
Claim 4
Dependent Claim
32 words
The apparatus of claim 2 wherein said workpieces comprise adjacent members with hollow portions and said retaining means comprise projections extending from said base member and snugly received within said hollow portions.
Claim 5
Dependent Claim
37 words
The apparatus of claim 1 wherein said means for feeding said strip solder material into said contact comprises drive means for moving said strip material longitudinally and guide means for directing said strip material into said contact.
Claim 6
Dependent Claim
26 words
The apparatus of claim 4 wherein said means for retaining comprises a base and said guide means is mounted on said base adjacent to said projections.
Claim 7
Dependent Claim
49 words
The apparatus of claim 1 wherein said means for feeding said strip solder material Into said contact comprises drive means for moving said strip material longitudinally and guide means for directing said strip material into said contact and said guide means comprises said cutting means and said shaping means.
Claim 8
Dependent Claim
68 words
The apparatus of claim 1 wherein said means for feeding said strip solder material into said contact comprises drive means for moving said strip material longitudinally and guide means for directing said strip material into said contact and said guide means comprises a stop means for engaging an intermediate portion of said cut strip to prevent distortion of said cut strip away from said workpieces during said bending.
Claim 9
Dependent Claim
55 words
The apparatus of claim 1 wherein said means for bending said strip solder material comprises a pair of arcuately movable members engaging the ends of said cut strip and movable through an arc corresponding to the shape of said sides of said assembly for bending said material around and in snug engagement with said sides.
Claim 10
Dependent Claim
53 words
The apparatus of claim 8 wherein said means for distorting further includes a stop means located intermediate the ends of said cut strip for engaging the strip on the side opposite said workpieces for preventing distortion of said strip away from said workpieces during said distorting of the ends of the strip material.
Claim 11
Dependent Claim
28 words
The apparatus of claim 1 wherein said means for cutting comprises a rotatable cutter adjacent to said means for feeding and forming a part of said shaping means.
Claim 12
Dependent Claim
44 words
The apparatus of claim 10 wherein said means for cutting comprises a cutting member mounted on said shaping means and including a cutting edge engaging a cutting surface that is integral with said guide means for severing said strip material at said guide means.
Claim 13
Independent Claim
106 words
The method of forming, cutting and substantially simultaneously applying strip solder material to an assembly comprising a plurality of workpieces preliminary to soldering the workpieces to another member, comprising: retaining the workpieces in predetermined positions relative to each other; feeding a strip of solder material into simultaneous contact with adjacent corresponding surfaces of said workpieces; cutting said strip material to provide a cut strip having a predetermined length sufficient for said simultaneous contact with the ends of said cut strip projecting beyond the sides of said assembly; and bending the projecting ends of said cut strip into wrap-around gripping engagement with said sides of said assembly.
Claim 14
Independent Claim
106 words
The method of forming, cutting and substantially simultaneously applying strip solder material to an assembly comprising a plurality of workpieces preliminary to soldering the workpieces to another member, comprising: retaining the workpieces in predetermined positions relative to each other; feeding a strip of solder material into simultaneous contact with adjacent corresponding surfaces of said workpieces; cutting said strip material to provide a cut strip having a predetermined length sufficient for said simultaneous contact with the ends of said cut strip projecting beyond the sides of said assembly; and bending the projecting ends of said cut strip into wrap-around gripping engagement with said sides of said assembly.
