Abstract
A wire winding apparatus for winding a wire on a bobbin includes a forming device forming the wire having a rounded cross section to have a polygonal cross section and a winding device winding the wire formed by the forming device on the bobbin.
Claims13
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.

A method for winding a wire on a bobbin comprising:
- directing a wire possessing a rounded cross-sectional shape to a rotating forming roll which is rotatably driven by a first motor to change the cross-sectional shape of the wire from the rounded cross-sectional shape to a formed cross-sectional shape different from the rounded cross-sectional shape;
- winding the wire possessing the formed cross-sectional shape on a bobbin through operation of a winding device which is operatively connected to and driven by a second motor;
- and
- servo-controlling the first and second motors to feed the wire out of the forming roller synchronously with the driving of the winding device.
