ABSTRACT:
In a coil-winding machine, an apparatus for routing a wire (10) from a storage pin (12) to a terminal pin (14) of a coil bobbin (16) mounted on a coil-winding arbor (18) includes routing and tension-controlling pins (50, 52, 54) for routing the wire to either a first set of terminal pins (14) in a first row (14B) or to a second set of terminal pins (14) in a second row (14A) and around the first set of terminal pins. An apparatus for reliably breaking the wire at the terminal pins includes a freely-rotatable breaker pin (80 or 84) which deflects the wire to the breaking point. The routing and tension-controlling pin(s) also serve to decouple at least part of the breaking tension from the storage pin. A cutting apparatus (116) shortens the length of wire extending from the coil of wire wrapped around and ultimately ejected from the storage pin, so as to reduce the likelihood of tangling.
