WIRE COILING METHOD

PURPOSE:To enhance the rate of filling of a wound wire and facilitate drawing- out of the same by allowing the relative speed of feeding the wire with rotation of a turntable to take up wire, to vary with a certain cycle period continuously, and coiling up the wire into a specific shape. CONSTITUTION:At a constant speed, a wire 2 at a supply stand 1 is drawn out by pinch rollers 4 driven by a motor 3 and taken up on a turntable 6 rotated by another motor 5. Here the wire 2 is first wound spirally in one plane from the minimum to maximum bias. adjoiningly one after another to be followed by winding from the maximum to minimum dias. adjoiningly one after another, and this operation is repeated. The feeding speed of the pinchrollers 4 shall be set constant, and the revolving speed of the turntable 6 be increased and decreased at a certain cyclic period. That is, a command signal to the motor 5 is previously set in a controller 8, and the change timing of the revolving speed to give command to the motor 5 is controlled by a rotary encoder 7.
