Abstract
Abstract A clip stack, a method of forming a rigidified joint, and the resulting joint. Filler material is positioned adjacent wires to be clinched by a clip, and is clinched with the wires to deform and to be compressed by the clip and wires to form a stronger and more rigid joint. The filler material may be carried by the clip, and may be severed from a clip stack joined by a strand of filler material from which filler material is severed as a clip is separated from the stack. The filler material may be at both sides of the stack and in an interference fit in notches in opposite sides of the clips of the stack.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
170 words
An elongate clip stack comprising a plurality of similarly shaped, non-nested adjacent clips, each clip being generally Ushaped in cross-section, and each clip including spaced, generally parallel, leg portions extending downwardly from a central web portion, each clip in said stack being positioned with its leg portions in contact with leg portions of next adjacent clips, each said clip defining notch means aligned with notch means of other of said clips longitudinally of said stAck, each leg portion having outer edges with an outwardly facing notch segment in an outer edge of each leg portion, the notch segments of each clip cooperating to form a said notch means, all of said notch means collectively defining a keyway extending longitudinally and opening outwardly of said stack, a filamentary key in frictional engagement within each of said spaced notch segments, whereby when a clip is separated from said stack, a segment of said filamentary key between said notch segments is severed from the key and is carried by a said separated clip.
Claim 2
Dependent Claim
170 words
An elongate clip stack comprising a plurality of similarly shaped, non-nested adjacent clips, each clip being generally Ushaped in cross-section, and each clip including spaced, generally parallel, leg portions extending downwardly from a central web portion, each clip in said stack being positioned with its leg portions in contact with leg portions of next adjacent clips, each said clip defining notch means aligned with notch means of other of said clips longitudinally of said stAck, each leg portion having outer edges with an outwardly facing notch segment in an outer edge of each leg portion, the notch segments of each clip cooperating to form a said notch means, all of said notch means collectively defining a keyway extending longitudinally and opening outwardly of said stack, a filamentary key in frictional engagement within each of said spaced notch segments, whereby when a clip is separated from said stack, a segment of said filamentary key between said notch segments is severed from the key and is carried by a said separated clip.
Claim 3
Dependent Claim
27 words
An elongate clip stack in accordance with claim 1, wherein said filamentary key is positioned in said notch segments completely within the confines of said outer edges.
Claim 4
Dependent Claim
40 words
An elongate clip stack in accordance with claim 1, comprising second notch segments in opposite outer edges of said leg portions, whereby opposed notch segments define a weakened zone to facilitate buckling of the clip when clinched to embrace wires.
Claim 5
Dependent Claim
56 words
An elongate clip stack in accordance with claim 1, comprising second notch segments and a second filamentary key in opposite side edges of said leg portions, whereby when a clip is separated from said stack, segments of said filamentary keys between said notch segments are severed from said keys and are carried by a separated clip.
Claim 6
Dependent Claim
30 words
An elongate clip stack in accordance with claim 1 wherein said filamentary key is generally circular in cross-section, and slightly larger in diameter than the width of each notch segment.
Claim 7
Dependent Claim
20 words
An elongate clip stack in accordance with claim 5, wherein said filamentary key is formed of a limber plastic material.
Claim 8
Dependent Claim
19 words
An elongate clip stack in accordance with claim 6, wherein said filamentary key is formed of a low-density polyethylene.
