Abstract
Apparatus for making the inductive component of a delay line containing multiple wire wound bobbins in a linear assembly. The component comprises a pair of multiple post bobbin units secured together with the bobbins interfitting in a row, each bobbin being wire wound. The apparatus simultaneously winds all bobbins on each unit with a uniform number of turns of wire, then secures the two units together while maintaining tension on the wire to prevent slippage. Bobbin units are fed into holders which are indexed successively to a winding station, an adhesive application station and a joining station, the completed components being wound on a storage spool while still in a string on the wires. The winding heads are driven to move in an elliptical path around the bobbin posts to provide clearance between the posts and to maintain constant wire tension in the windings.
