摘要：According to the proposed method, wire is wound on each step of a steppedformer to produce a coil of a preset length. After a completion of each new coil, the wireis successively transferred from one step to another. As the winding of the wire on onestep of the former is in progress, the coil produced on another step is moved along theformer by a pitch greater than the length of this coil so as to transfer the coiled wire tothe vacated step. The method presupposes the use of a stepped coil former comprisingconcentrically arranged mandrels, a coupling means with movable elements which arearranged in rows and can alternately be drawn out in the transverse direction, and a coiltransfer mechanism equipped with movable pushers. The method is carried out with theaid of an apparatus comprising said stepped former, a winding head with a wire guiderotatable around the stepped former, and a receiving mandrel to receive coils removedfrom the stepped former. A switching device is provided for the transfer of the wire fromone step of the former to another. Finally, the apparatus includes a rod attached to the
male mandrel of the former and coupled to a device whose function is to lock thestepped former in place and prevent its rotation.
