Device Facilitating the Treatment and Preparation of Transistors

This device is for feeding transistors to testers, machines cutting and redressing wires, etc.

A. 008 thick RISLAN* tape 1 has three rows of small holes 2, 3 and 4 through which are threaded the transistor wires 5. Tape 1 two rows of holes (not shown). The tape, which is sufficiently rigid to prevent any distortion by traction, is flexible enough to be deformed by a press provided to set transistors in the tape. This press has on its matrix 6 and its punch 7 associated recesses and bumps which deform the tape above and below the transistor wires.

The wires are guided through tunnels 8 and each one passes through three holes alternately above and below the tape. Two adjacent wires are threaded according to reversed alternations. When the press moves up, the tape tends to reassume its initial shape, and bearing against the wires maintains the transistors in their places. The loaded tape is wound on a reel. Between each turn there is inserted a tape of soft plastic compensating for the thickness of the transistor heads. *RISLAN is a trademark of Organico, Paris, France.
