ABSTRACT:
A method and a device for winding wire spools for electric machines allow rapid change of the delivery spools (28, 28a). The wire lead of a new delivery spool is affixed in a holder (48, 48a) ready for the connection. The remainder of wire length of the preceding delivery spool is measured and winding nozzle (14) of the winding device is stopped at the time point when the wire length required for completion of a spool is found between the winding nozzle and the attachment point (48, 56). Then wire (20) is cut off at the attachment point, and the wire end to the rear is connected by means of a wire connection unit (56) with the ready wire lead of the next delivery spool.
