ABSTRACT:
A winding apparatus for winding a magnetic element through a form, the apparatus having at least one chain which has a plurality of magnetic carrier units disposed about the form for loading the coil of the element through the form and, after loading, for winding the element from the loading coil about the form under tension to tightly wind a final coil. Each carrier unit includes a device for generating a magnetic force to magnetically hold the element and to release portions of the element when tension on the element between the outer periphery of the final coil and the advancing point of separation of the element from the inner periphery of the loading coil exceeds the magnetic force exerted by the carrier units. The winding apparatus also includes a device for driving the chain during loading and winding, and structure for defining the path of the chain during loading and winding.
