IPC: B65H59/38
Filed: 1984-11-28
Abstract: PURPOSE:To reliably perform alignment-winding even at the winding kettle end by using the two-step speed change control of acceleration and stop that a slider is once accelerated at the winding kettle end moved, stopped, then delay control is again performed. CONSTITUTION:Suppose now a winding kettle 2 is rotated CW as seen from the R direction. If the first layer is wound in the Y direction, when a wire 1 reaches T7 while maintaining an incident angle alpha, a slider is relatively quickly accelerated via the detection of the collar end. The delay control being so far applied is now not applied, and the wire 1 becomes parallel with the collar end. Next, when the wire 1 reaches the collar end, the slider is stopped. Then, the slider is half turned, the second-layer winding starts at the T9 position, and the slider reaches T9' while being stopped. After the slider is correctly put in a wire pitch groove at the T10 position which is half turned from T9', the slider is restarted from the T11 state, then the delay control with an incident angle alpha in the X direction is started, and alignment-winding is reliably performed.
