ABSTRACT:
Disclosed is a process and an apparatus for use therewith for maintaining a constant material web speed during winding of the material onto a driven roll. The process comprises adjusting the speed of the drive motor of the roll to be linearly proportioned to its control voltage; and, as the diameter of the roll increases due to the winding of material thereon, reducing the speed of the drive motor in accordance with a hyperbolic curve relating motor speed to the diameter of the roll characteristic of the winding operation.
