Abstract (en)

[origin: EP1335055A1] A weft feeder for textile machines, wherein a swivel arm (13) winds a weft thread onto a stationary drum (12) that is supported coaxially and rotatably on the motor shaft (14) of the swivel arm. The drum is kept in a fixed angular position by the mutual attraction between a first set of magnets (18a), which are received in respective first recessed seats (19a) on a first annular surface (26) of the motor housing (11) which is coaxial to the motor shaft, and a second set of magnets (18b), which are received in respective second recessed seats (19b) on a second annular surface (27) of a support at the base of the drum, facing the first annular surface. Each seat of the first and second sets has a bottom provided with a ferromagnetic plate (21a, 21b), preferably of neodymium, which therefore performs the dual function of retaining the respective magnet in its seat and of conveying its lines of flux into the region of interest where the swivel arm rotates. <IMAGE>
