Abstract
A perfect layer coil winding apparatus capable of automatically forming a perfect layer coil from the initial stage of winding operation without being affected by non-uniformity in diameter of a wire and width of a bobbin for winding the wire thereon is disclosed which performs the following operation: the width of the bobbin is calculated from the position of each of two flanges which is detected by each of two electric micrometer, the number of turns per layer is calculated from the width of bobbin and the diameter of wire, the winding width of the bobbin required to conduct the perfect layer coil winding from the number of turns per layer to adjust the winding width of the bobbin, the supply position of wire is adjusted on the basis of the position of first flange, the diameter of wire and the standby position of a pair of rollers, the bobbin is rotated with the wire pushed against the first flange by a push plate to start the winding operation, and when the degree of rotation of the bobbin reaches a predetermined degree, the push plate is spaced apart from the bobbin and the supply position moves in synchronism with the rotation of the bobbin while following a position on the b…
