The selection of electric winder drives for the paper industry

ELECTRIC winder drives are used universally throughout the paper industry, and electric hackstand brakes are being used in increasing numbers as these winder drives are required to service the new wider and faster-speed paper-making machines. D-c adjustable voltage winder drives are used on all modern high-speed winders. Although some small, slow-speed winders utilize a-c drives, this paper will concern itself with d-c drives having either mechanical or electric hackstand brakes.
