Abstract
The head (11) of a winding form (1), including two metal paths (12a, 12b), is held between two jaws (30, 31) of the chuck (3). A winding mechanism (40) leads one end of a winding wire (23) above one of the metal paths, being guided by a first guide pin (39a) and a front face (30b) of one of the jaws. After having executed a winding (2) about the core (10) of the winding form, the winding mechanism leads the other end of the winding wire (24) away, passing above the other metal path and being guided by another guide pin (39b; 39c). The chuck used in this way makes it possible to wind fine wire about the core of a very small winding form and to weld the ends of the winding wire to the metal paths without having to go and pick up these ends.
Claims6
A coil-winding method utilizing a chuck having two jaws for holding a winding form having a head including at least one metal portion during winding of a winding wire about the winding form, the chuck comprising a plurality of guide pins for guiding the winding wire, and the jaw of the chuck being shaped in such a way as to give access to the at least one metal portion of the head of the winding form and having at least one front face thereof adapted to act as a wire guide, and a winding mechanism, comprising the steps of:
- a.) leading the winding wire by relative movement between said chuck and said winding mechanism onto one of the metal portions, the winding wire being guided by one of the guide pins and by said front face;
- b.) execution of the winding by relative rotational movement between said chuck and said winding mechanism;
- and
- c.) leading the winding wire away by relative movement between said chuck and said winding mechanism, the winding wire being guided by another of the guide pins to pass over another of the metal portions.
