Abstract

The core winding device enables the threading of apertured magnetic cores in two-dimensional arrays. It provides an individual supporting member for each core. Each member is rotatable to fully expose the minute core apertures along either of two coordinate directions. This permits rapid insertion of the threading needle and filament.

Core Winding Device

The core winding device enables the threading of apertured magnetic cores in two-dimensional arrays. It provides an individual supporting member for each core. Each member is rotatable to fully expose the minute core apertures along either of two coordinate directions. This permits rapid insertion of the threading needle and filament.

A plurality of supporting members or spindles 11 is arranged as a two dimensional matrix. Each spindle is divided into two portions, upper portion 12 and lower portion 13. Each is supported by shoulders 14 between plates 15 and 16 and plates 17 and 18, respectively. Portion 12 supports two guide fingers 21 and 22 fixed to surface 19. The fingers are spaced from each other at a distance sufficient to permit easy insertion, e.g., by the use of vacuum in conjunction with vibration, of cores 20 in slots cut in each guide finger. In order to facilitate the loading of cores in their respective spindles, there is a removable guide piece 23 having apertures 24. These conform closely with the contour of guide fingers 21 and 22 and correspond in location with each spindle. Spacers 25 are used during the core winding operation. They serve as shims to vertically position the guide piece 23 and as a lower guide for the threading needle. The spacers extend the full length of the spindle rows and are placed between adjacent parallel rows at right angles to grooves 26 of guide piece 23. The thickness of the spacers depends upon the...
