Shuttling Device For Strand Material

The device is used where the free end of a long rope, wire, thread or the like must be passed back and forth through a work piece such as a toroidal core or core plane.

The drum units 1 and 2 are identical. The mechanical arrangement of unit 1 is described. A drive rim 3, with two pulleys 4 and 5 mounted on its outer perimeter, is pinned to a shaft 6 adapted to rotate in either direction by suitable drive means. Two pinion gears mounted on the hub of rim 3 and two bevel gears freely mounted on the shaft 6 form a two to one differential 7. Two drums 8 and 9 are keyed to hubs of the bevel gears by means of splines or ballgrooves which allow drums 8 and 9 to turn with the bevel gears and slide as a unit parallel to the shaft 6. The drums 8 and 9 are fitted with single direction clutches which lock drum 8 during winding and lock drum 9 during unwinding. With one drum locked, the differential 7 causes the other to rotate twice as fast as rim 3.

A strand 10 is about to be wound on unit 2 and unwound from 1.

The strand extends from a needle 11, guide and clamp means 12, pulleys 13 and 14, guide and clamp means 15, through suitable mounted work piece 16, guide and clamp means 17, around drum 8, pulleys 5 and 4, around drum 9, guide and clamp means 18 to the end 19 at work piece 16. The strand 10 is shown ready to be wound on drums 20 and 21 by drive rim 22 pinned to shaft 23.

As shaft 23 and rim 22 rotate in the direction shown, drum 21 is locked and drum 20 rotates at twice the speed of rim 22. As a result, drum 20 takes on two turns of wire for every turn of rim 22.

As rim 22 rotates, however, it places one turn on stationary drum 21 across pulleys 13 and 14. After every revolution of rim 22 there is an equal number of turns on each of dru...
