Abstract
Abstract A length of wire is formed to a noncircular cross section preparatory to forming the wire into clips. The noncircular cross section is formed by a pair of rollers and the rolled wire is oriented for use in the clip forming machine by guiding the rolled wire in a relatively large loop so that the tendency for the wire to twist after rolling is readily overcome and so that the proper orientation of the wire is achieved while feeding the wire to the clipping apparatus.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
73 words
In the method of making a clip of noncircular cross section in a wire cutting and forming means the steps of: providing a source of wire, feeding said wire from said source, forming said wire to a noncircular cross section during the feeding thereof, guiding the formed wire to orient the same in a relatively large loop and thereafter, feeding the formed wire from said loop to said wire cutting and forming means.
Claim 2
Dependent Claim
73 words
In the method of making a clip of noncircular cross section in a wire cutting and forming means the steps of: providing a source of wire, feeding said wire from said source, forming said wire to a noncircular cross section during the feeding thereof, guiding the formed wire to orient the same in a relatively large loop and thereafter, feeding the formed wire from said loop to said wire cutting and forming means.
Claim 3
Dependent Claim
39 words
The method of claim 1 wherein said noncircular cross section includes a flat on one side of said wire and said forming step tends to bend said wire into a loop having said flat on the outer periphery thereof.
Claim 4
Dependent Claim
32 words
The method of claim 2 wherein said wire is guided after said forming step to provide a loop of greater size then the size of the loop created by said forming step.
Claim 5
Dependent Claim
19 words
The method of claim 3 wherein said last mentioned guiding step includes bending said wire toward a straight condition.
Claim 6
Dependent Claim
70 words
Apparatus for forming wire clips of noncircular cross section comprising: means for establishing a supply of wire in a continuous length, roller means for forming said wire to a predetermined noncircular cross section, guide means for guiding said formed wire in a relatively large loop, wire cutting and forming means for making clips, and feeding means for feeding said wire from said loop to said wire cutting and forming means.
Claim 7
Dependent Claim
70 words
Apparatus for forming wire clips of noncircular cross section comprising: means for establishing a supply of wire in a continuous length, roller means for forming said wire to a predetermined noncircular cross section, guide means for guiding said formed wire in a relatively large loop, wire cutting and forming means for making clips, and feeding means for feeding said wire from said loop to said wire cutting and forming means.
Claim 8
Dependent Claim
37 words
Apparatus according to claim 5 wherein said means for establishing a supply of wire includes a drum of wire, variable speed means for rotating said drum on its periphery for feeding said wire toward said roller means.
Claim 9
Dependent Claim
29 words
Apparatus according to claim 5 wherein said roller means includes a pair of rollers driven in opposite directions at the same speed, variable speed means for driving said rollers.
Claim 10
Dependent Claim
35 words
Apparatus according to claim 7 wherein a follower is positioned in engagement with said loop, means connecting said follower with said variable speed means for automatically controlling said speed by the size of said loop.
Claim 11
Dependent Claim
27 words
Apparatus according to claim 5 wherein straightening rollers are interposed between said loop and said wire cutting and forming means for straightening the wire from said loop.
