<p>The machine comprises a bed (1), Fig. 1, on which is mounted a turntable (2) with several mandrels (3) installed radially thereon, each mandrel, Fig. 3, comprising a body (13) with a tapered supporting sleeve (14), a slotted head flange (15), a removable tail flange (16), a carrier (17) with radial slots (18) and sectors (19) received in the carrier slots and having inclined inner surfaces cooperating with the taper surface of the support sleeve so that the sectors are retracted radially inwardly when the flange (16) is removed. Teeth (20) on the sectors form, when the sectors are expanded through axial slots in a bobbin having flanges 25, 25_, orthocyclic grooves (21). Elastic rings (22) are fitted around the sectors (19). The machine also includes a mechanism for correcting the winding pitch during the winding of a coil, and a wire placer (7) which acts as a wire tensioner and is adapted to ensure the correct initial winding pitch. The bobbin may be omitted. <IMAGE></p> |
