Abstract
The invention provides a coil winding apparatus which is simplified in structure, reduced in cost and improved in operation efficiency. The coil winding apparatus comprises a housing intermittently rotatable around a fixed axis between first and second positions, a plurality of spindles mounted for rotation on front and rear faces of the housing, a pair of drive sections including a bidirectional motor and provided independently of each other for transmitting rotation of the motor to rotate the spindles, an insulation sheet supply section opposed to the spindles on one of the faces of the housing when the housing is at any of the first and second positions for supplying films to bobbins mounted on the spindles, and a wire supply section for supplying wires to bobbins mounted on the other spindles. Since the drive sections are provided independently of each other for the different spindles, the directions and the speeds of rotation of the spindles can be set arbitrarily.
