Abstract
796,089. Automatic speed control systems for web winders. CROWTHER, Ltd., KIMBER, R. A., and COLEMAN, P. E. R. Aug. 5, 1954 [May 5, 1953], No. 12420/53. Drawings to Specification. Class 38 (4). In a system for maintaining a constant linear speed of a filament or web being wound on a roll, a tachometer generator is driven by drum held against the periphery of the roll, and the difference between the generator output and a reference voltage, controls a grid-controlled rectifier supplying the roll-drive-motor. To provide a wide speed control range, changespeed gears may be used in the tachometer generator drive, or with an A.C. tachometer generator, a tapped transformer.
