Abstract

The present machine is concerned with coating electrically conductive wire with one or more layers of plastic insulation. This is applied in spaced areas along the length of the wire. Thus, selected intervals of wire remain bare for connections as by soldering.

Wire Coating Machine

The present machine is concerned with coating electrically conductive wire with one or more layers of plastic insulation. This is applied in spaced areas along the length of the wire. Thus, selected intervals of wire remain bare for connections as by soldering.

In the case of connecting small delicate components, it is advisable to keep the heat of soldering as low as possible and the soldering time as short as possible to prevent damaging the parts. Such quickly established connections can be made with the kind of insulated wire prepared by this machine. Here, a wire is treated to have alternating predetermined portions of bare and insulated copper wire, thus having bare copper sections readily available for low temperature soldering.

The wire 10 to be coated is advanced off spool 11 and directed through one of a series of V-grooves in a first guide wheel 12. From there the wire passes between a pair of polyurethane applicators 13 and 14, through curing oven 15, around the second grooved guide wheel 16 and back to another groove in wheel
12. Wire 10 is passed between the insulation applicators 13 and 14 and through the oven 15 as many times as desired to add thickness of insulation on the various passes separated by the several V-grooves. Finally, the coated wire 10 is taken up on winding spool 17. Both guide wheels 12 and 16 and the take-up spool 17 are driven by belts 18, 19, 20 and 21 connected to drive motor 22.
