Abstract
A control system for a ring spinning machine and method wherein yarn is wound in cop-type manner on spinning tubes supported on spindles driven at relatively lower speeds during the beginning and ending stages of the winding operation and relatively greater speeds during the intervening stage of the winding operation. Yarn is applied to the spinning tubes by reciprocating a ring rail or other yarn-carrying member along the spinning tubes with the extent of the reciprocating motion of the ring rail being incrementally shifted along the spinning tubes over the course of the winding operation. The present control system performs the shifting of the ring rail in relatively shorter increments during the intervening stage of the winding operation when spindle speed is relatively increased than during the beginning and ending stages of the winding operation when spindle speed is relatively decreased, which maximizes the yarn capacity of the spinning tubes.
