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.

Abstract: A method and device for the production of cover strips which are to be inserted into the grooves of stators of electric machines, from a supply of strip material provided on delivery rolls. The guide channel (26) for cover strip material (12) has several feed passages (46, 46'), which can be brought individually into connection one after the other with the main part of guide channel (26). Thus it is possible to thread the lead of a new delivery roll into its feed passage (46, 46') of the guide channel while the machine continues to run, so that when delivery rolls (16, 16') are to be changed, only a mechanical change of position of feed passages (46, 46') need be undertaken. The down time of the machine is thus greatly shortened.
