  • Patent number: 7267296
    Abstract: A method and apparatus for winding multi-pole stators formed by a sheets stack ferromagnetic core, having a plurality of radially extending poles defining grooves between them. Said wireis wound about said pole extensions, spooled by a flier, and guided by shrouds, which move radially with respect to said stator overlapping the respective pole extension. The shroud) is equipped with a housing suitable for receiving said hook, so that said shroud) makes a guide for said wire on said hook. Said flier is rotated about its own axis in order to deposit said wire onto said hook. Then said shroud is withdrawn up to disengaging said hook from said housing. In case said wire must form a loop or “alpha” about said hook, after withdrawal of said shroud, said hook is shielded by means of a shield in order to force said wire in a chosen position and to slide on said shield during a backwards movement of said flier.

  • Patent number: 6848646
    Abstract: A method for guiding the wire (8) on multi-pole stators (1) that can be wound by a flier-type machine, wherein the stators (1) have a core (3) with poles (4) defining between them a plurality of grooves (5), and wherein the wire (8) is wound about the poles (4) guided by first fixed shrouds (11) and second mobile shrouds (12?), which move radially for laying the wire (8) along the poles same. At winding the approaching step of third shrouds (21) against the boundary of the pole (4) is provided. The third shrouds (21) and the second shrouds (12?) move integrally when approaching or moving away with respect to the stator, whereas during the winding step they are movable relative to each other, so that the third shrouds (21) are fixed against the stator (1) and guide the wire (8) in the grooves (5), whereas the second shrouds (12?) move for laying the wire (8) about the poles (4).
