Abstract

The device illustrated in the figures eliminates the friction of a fixed guide in guiding wire onto a winding spool, and it also insures a positive lay of the wire as it traverses across the center of the take-up spool. As illustrated in Fig. 1, a side view of the winding apparatus showing the guide roller combination, the wire to be wound on a spool passes between two guide rollers 1. A 90 degree annular groove 2 is at the periphery of each guide roller 1. The guide rollers 1 are mounted on a freely floating bracket frame 3 which includes slide bearings 4, to allow rollers 1 to traverse up and down the length of studs 5. The free-floating feature of the guide roll and mounting bracket combination allows for the increase in coil diameter, which takes place as the wire is wrapped onto the spool.

Positive Level Wind Control of Wire

The device illustrated in the figures eliminates the friction of a fixed guide in guiding wire onto a winding spool, and it also insures a positive lay of the wire as it traverses across the center of the take-up spool. As illustrated in Fig. 1, a side view of the winding apparatus showing the guide roller combination, the wire to be wound on a spool passes between two guide rollers 1. A 90 degree annular groove 2 is at the periphery of each guide roller 1. The guide rollers 1 are mounted on a freely floating bracket frame 3 which includes slide bearings 4, to allow rollers 1 to traverse up and down the length of studs 5. The free-floating feature of the guide roll and mounting bracket combination allows for the increase in coil diameter, which takes place as the wire is wrapped onto the spool. It also prevents adding a bend in the vertical plane of the wire as it passes through the rolls and onto the spool.

As shown in Fig. 1, studs 5 are mounted to a traverse plate 6 which is driven back and forth by a double-helical screw thread 7, driven by a motor, not shown. A split nut follower is incorporated in the bracket 6 which switches over from one helix to the other at either end of the helical traverse, to reverse the direction of travel of the wire guiding rollers back and forth across the length of the spool.

Another feature is illustrated in Fig. 2, in which a top view of the guide roller and bracket combination is illustrated. Guide rolls 1 lie in an offset relationship with one of the rollers 1 being closer to the take-up spool than the other. This offset produces the result illustrated in Fig. 3 and in the expanded view in Fig. 4, which shows the final aperture taken on a line of sight perpendicular to the transverse axis of studs 5 in the plane of rollers 1 (which is illustrated by the dashed line of sight in Fig. 2) can be adjusted to be exactly the wire size diameter.
