Abstract (en)
Electromagnetic device for stopping the weft thread in a weft feeder for weaving machines, of the type comprising a slider (C), apt to be moved along an alternate rectilinear path between two end-stop positions responsive to the activation of electromagnetic coils (B) housed in a case (6), consisting of a bush-shaped ferromagnetic core (3), of a cylindrical end-piece (1) for stopping the weft thread projecting from one side of said ferromagnetic core (3) and of an intermediate element (2) forming the mechanical connection between said ferromagnetic core (3) and said end-piece (1). Said intermediate element (2) is a cylindrical aluminium element which is fastened, through a mechanical coupling with interference, within the cylindrical inner cavity of said bush-shaped ferromagnetic core (3), and which further has an axial cylindrical inner cavity (2c) in which said end-piece (1) is fastened, through a mechanical coupling with interference.
