Abstract
A winding machine for winding a strand onto a tubular support to form a strand package, and including a spindle on the which the tubular support is mounted for rotation therewith. A motor is provided for rotating the spindle. A reciprocating traverse mechanism, including a strand guide, guides the strand onto the tubular support at a predetermined traverse stroke and wind ratio. The traverse mechanism includes servo-motor for selectively starting and stopping reciprocating movement of the strand guide in accordance with the predetermined traverse stroke and wind ratio, and a programmable servo-controller accepts data inputs reflecting the desired traverse stroke and wind ratio and outputting data to the servo-motor reflecting the desired traverse stroke and wind ratio.

A winding machine for winding a strand onto a tubular support to form a strand package, and comprising:
- (a) a spindle on the which the tubular support is mounted for rotation therewith;
- (b) a motor for rotating the spindle;
- (c) a reciprocating traverse mechanism, including a strand guide, for guiding the strand onto the tubular support at a predetermined traverse stroke and wind ratio, said traverse mechanism comprising:
- (i) a servo-motor for selectively starting and stopping reciprocating movement of the strand guide in accordance with the predetermined traverse stroke and wind ratio;
- and
- (ii) a programmable servo-controller for accepting data inputs reflecting the desired traverse stroke and wind ratio and for outputting data to the servo-motor reflecting the desired traverse stroke and wind ratio.
A method of winding a strand onto a tubular support to form a strand package, and comprising the steps of:
- (a) providing a spindle on the which the tubular support is mounted for rotation therewith, a motor for rotating the spindle, and a reciprocating traverse mechanism, including a strand guide, for guiding the strand onto the tubular support at a predetermined traverse stroke and wind ratio;
- (b) generating data inputs reflecting the desired predetermined traverse stroke and wind ratio;
- (c) outputting data to a servo-motor driving the strand guide, said data reflecting the desired traverse stroke and wind ratio;
- (d) selectively starting and stopping the servo-motor and thus the reciprocating movement of the strand guide in accordance with the predetermined stroke and wind ratio.
