Abstract

This apparatus is for winding ribbon or wire around a hollow core, such as one used in a pulse transformer. The wire being wound is moved solely by pneumatic devices. Core 10 is held and retained by chuck 11 having fingers 21. These engage core 10 between the sites of the windings to be applied to it. Chuck 11 seats core 10 intermediate upper and lower supporting blocks. To permit the seating or removal of chuck 11, the upper block can be moved out of engagement with the lower block. Chuck 11 is indexable to rotate the core 10 about its own axis. The upper block is independently indexable about this axis.

Pneumatic Core Winding Apparatus

This apparatus is for winding ribbon or wire around a hollow core, such as one used in a pulse transformer. The wire being wound is moved solely by pneumatic devices. Core 10 is held and retained by chuck 11 having fingers 21. These engage core 10 between the sites of the windings to be applied to it. Chuck 11 seats core 10 intermediate upper and lower supporting blocks. To permit the seating or removal of chuck 11, the upper block can be moved out of engagement with the lower block. Chuck 11 is indexable to rotate the core 10 about its own axis. The upper block is independently indexable about this axis.

Ribbon 12, comprising a plurality of strands of wire to be wound about core 10, is considered to have already been fed into the apparatus and seated in position 1. This description covers the operation of the apparatus for effecting one full turn. It does not discuss the loading of the core and the ribbon or the subsequent unloading.

First, air pressure is applied from conduit 16 against ribbon 12 to drive it into chamber 17 where it assumes position 2. This completes the first quarter turn of ribbon 12 about core 10.

Next, air pressure is applied against ribbon 12 from conduit 18 while the air pressure in conduit 16 is terminated. This drives ribbon 12 into chamber 19 where it assumes position 3. This completes the second quarter turn about core
10. While ribbon 12 is in position 3, the upper block is rotated about the axis of c...
