Abstract:
1. A winding apparatus for winding a wire on a bobbin comprising: a forming device which receives the wire when the wire possesses a rounded cross-section and forms the wire having the rounded cross-section into wire having a cross-section different from the rounded cross-section, the forming device comprising a forming roller operatively connected to a first motor so that operation of the first motor rotates the forming roll; a winding device configured to wind the wire formed by the forming device on a winding surface of the bobbin; a second motor operatively connected to the winding device so that operation of the second motor drives the winding device to wind the wire on the surface of the bobbin; and the first and second motors being servo-controlled so that the wire is fed out of the forming roller synchronously with the driving of the winding device.
