Abstract

The drawing shows a method and apparatus for winding small ferrite cores 2 on the X end Y wires of a memory array. In the assembled array, each core 2 is located at the intersection of an X wire and a Y wire. Since cores 2 are positioned at 45 degrees to the wires of the array, the opening in a core 2 available to a wire is significantly less than the inside diameter of a core. The apparatus turns cores 2 so that they face at about 60 degrees to the axis of the threading wire for both the X wires and the Y wires.

Automatic Winding of Continuous Core Memory Planes

The drawing shows a method and apparatus for winding small ferrite cores 2 on the X end Y wires of a memory array. In the assembled array, each core 2 is located at the intersection of an X wire and a Y wire. Since cores 2 are positioned at 45 degrees to the wires of the array, the opening in a core 2 available to a wire is significantly less than the inside diameter of a core. The apparatus turns cores 2 so that they face at about 60 degrees to the axis of the threading wire for both the X wires and the Y wires.

First, cores 2 are mounted in slots 4 formed in an indexing frame 5. The latter has low side walls 6 that help to retain the cores. These are aligned at 60 degrees to the longitudinal axis of frame 5. In this position, they present a large opening to the X wire which then is threaded through the core apertures. For threading the Y wire, frame 5 is positioned with cores 2 facing the Y wires at 60 degrees.

When the Y wires are threaded through the cores, frame 5 is swung into the normal direction parallel to the X axis of the array and cores 2 are aligned at 45 degrees to the wires.
