Abstract
A microprocessor-based system for controlling a product roving process employing a pair of substantially identical high speed creel assemblies each of which being adapted to operatively carry a plurality of strand-serving packages having individual fiberous strands of material wound thereon. The individual strands are served out and gathered into groups to be collected as a roving on a collet which is turned by a winding motor. The microprocessor system controls the speed and acceleration of the winding motor and the number of strands which are being wound to form a desired product package. The system provides for a plurality of standby strands which are available to be automatically inserted into the system when a break or 'end out' condition occurs in any of the operating strands being wound.
