ABSTRACT:
A vertical winder for winding a web on a center wound roll has a fixed vertical frame (A) supporting a carriage for vertical movement thereon. The carriage has a vertically movable upright section (B) and a cantilevered section (C) positioning at least one elongated driven roll (D) above the center wound roll. A drive motor (E) mounted on the carriage drives the elongated drive roll, and a fluid-operated cylinder (F) positions the elongated carriage between lowered and raised positions during the build of a center wound roll. The method provides for delivering a web in open width at a central location to the center wound roll during driving and building of the center wound roll.
