Abstract:
An apparatus for manufacturing a rectangular-wire coil, comprising:feeding means for supplying material wire;rectangular forming means with rectangular forming rollers for deforming the material wire whereby the material wire provided through the feeding means is deformed to form wire with a rectangular cross section;coil forming means whereby the rectangular wire is wound on a winding form to form a rectangular-wire coil and the coil forming means includes a winding-form motor for rotating said winding form, wherein forming rectangular wire and winding on the winding form are performed in a sequence of continuous processes which include rotating the winding form using a turning force generated by the winding-form motor, the rectangular wire pulled so as to provide the tension required for extracting the material wire from the rectangular forming rollers and winding on the winding form; andwinding-form motor control means for controlling the winding-form motor in order to vary a rotational speed of the motor according to a rotation angle of the winding form.
