Magazine for winding wire on endless annular members or cores

Abstract

A wire magazine for winding wire for use in a winding machine for the winding of elongate members or cores, preferably endless cores, comprises two annular halves (9, 10) which are designed with thin walls of a substantially semicircular cross-sectional form to provide substantially closed storage space. The halves are separated by a wire filling slit (11) on the external side of the magazine and a bottom slit (12) on the underside of the magazine facing it axis of revolution, said bottom slit (12) being defined by edge portions of the two halves (9, 10) having walls, the surfaces of which deviate from a planar parallel relationship to the symmetry plane of the wire magazine normal to the axis of revolution. With this design of the wire magazine, an optimum residual hole condition in the winding of toroidal cores is obtained and simultaneously an efficient holding of winding wire within the magazine after cutting of the wire is secured in addition to an improved security against slipping of the wire drawn out through the bottom slit (12) and an optimum possibility for correct control of the friction between the wire and the walls of the bottom slit (12) and, thereby, of the wire tension. The walls of the bottom slit may, for example, have a longitudinal wave form.
