Abstract :
A TYPICAL electric drive for a modern 84-inch supercalender and winder consists of a 200-horsepower adjustable-speed driving motor, two 20-horsepower motors for winder drums, a 150-kw variable-voltage motor generator set with 30-kw winder generator and exciter, full magnetic control with large motor-operated rheostat, and an operator´s panel. The drive will provide a threading speed of 50 feet per minute and a wide range of many productive calendering speeds to a maximum which may be 2,000 feet per minute. With auxiliary equipment on the winder slitters, and pressure-applying arrangement, the operator has full control of the calender speed, starting and stopping, roll pressures, and winder tensions at a central point.
