摘要： A coil manufacturing apparatus includes a bending unit (15) configured to carry out a bending process in which a metal sheet (2) fed by a feeder (14) is bent before rewound onto a former (16) and a control unit (20) configured to control the bending process based on a feed amount of the metal sheet (2) by the feeder (14) so that a winding start of the metal sheet (2) is shaped according to an outer peripheral shape of the former (16) and thereafter, according to an outer peripheral shape of the metal 1 sheet (2) lap-wound onto the former (16).
