Abstract
Abstract A process and apparatus for the manufacture of a continuous web of parallel lead electronic components is provided. Wire for the leads of the components is straightened, cut into uniform predetermined lengths, formed into a U-shaped leadwire and fed onto a continuous moving support band. The parallel leads of the U-shaped lead wires are secured to the support band by adhesive tape at the same time the spacing between the parallel leads is controlled to insure dimensional accuracy. The parallel leads of the open end of the formed lead wires are formed with a cross-over portion and an electronic component element is connected to the formed end.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
128 words
A process for the preparation of a continuous web of parallel lead electronic components comprising: continuously feeding a continuous length of a support band; forming a wire into a U-shaped lead wire having a portion of parallel leads; positioning said U-shaped lead wire transversely onto said support band with said parallel leads projecting from both edges of said support band and controlling the spacing between the parallel leads in at least one portion of said parallel leads projecting from said support band; securing said U-shaped lead wire to said support band by an adhesive tape at the same time the spacing between said parallel leads is being controlled in said at least one portion; and connecting an electronic component element to one end of said U-shaped lead wire.
Claim 2
Dependent Claim
128 words
A process for the preparation of a continuous web of parallel lead electronic components comprising: continuously feeding a continuous length of a support band; forming a wire into a U-shaped lead wire having a portion of parallel leads; positioning said U-shaped lead wire transversely onto said support band with said parallel leads projecting from both edges of said support band and controlling the spacing between the parallel leads in at least one portion of said parallel leads projecting from said support band; securing said U-shaped lead wire to said support band by an adhesive tape at the same time the spacing between said parallel leads is being controlled in said at least one portion; and connecting an electronic component element to one end of said U-shaped lead wire.
Claim 3
Dependent Claim
22 words
The process of claim 1, wherein the spacing between the parallel leads is controlled by at least one dimension controlling tool member.
