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 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.

Microprocessor controlled product roving system

An elevator system including an elevator car mounted in the hoistway of a building having a plurality of floors, hoistway doors at the floors, and a floor selector for controlling the movement of the elevator car. Each hoistway door includes address indicia related to the address of its associated floor in the building. A detector on the elevator car reads the indicia during movement of the hoistway door. The address read from the hoistway door is loaded into a car position memory associated with the floor selector.
