Surface winder apparatus and method

摘要

The speeds of support rolls (A) and (B) of a surface winder are controlled during winding by sensing means including a movable roll (C) for detecting variations in web tension. The motors (F) and (G) are controlled responsive to the sensing means by motor control circuitry (H) and, through respective drives (D) and (E), independently drive the rolls (A) and (B).
