Patent ID: 6848646

Claim:
A method for guiding a wire ( 8 ) on multi-pole stators ( 1 ) that can be wound by a flier-type machine, wherein said stators ( 1 ) have a core ( 3 ) from which a plurality of branches ( 6 ) radially extend with poles ( 4 ) defining between them grooves ( 5 ), said poles ( 4 ) having longitudinal edges, which define slits for reaching the grooves ( 5 ), and circumferential edges, which define the stack height of the stator, and wherein the wire ( 8 ) is wound about said branches ( 6 ) by means of at least a rotatable arm guided by first fixed shrouds ( 11 ), which define a funnel to avoid hits of the wire ( 8 ) against the longitudinal edges of adjacent poles ( 4 a , 4 b ), and second mobile shrouds ( 12 ″), which define a couple of chute guides that pass beyond the circumferential edges of the pole ( 4 ) and that move radially for laying the wire ( 8 ) along the branches ( 6 ), characterised in that at winding an approaching step is provided by third shrouds ( 21 ) fixed in position against an outer radial boundary of the pole ( 4 ), said third shrouds ( 21 ) guiding the wire ( 8 ) to avoid hits of the wire ( 8 ) against the longitudinal edges of the pole.
