ABSTRACT:
An apparatus is illustrated for unwinding a web, such as cloth or paper, which utilizes a driven belt having a width in excess of the width of the web forming a cradle for a cloth roll and the like with adjusters for adjusting the path of travel of the belt including at least one oscillatable roll over which the belt passes and which is oscillated responsive to sensors sensing the position of the belt. A pair of downwardly and inwardly tapering guides are provided spaced opposite respective ends of a tubular core for maintaining proper position of the web roll carried thereby. A pair of downwardly and inwardly tapering guides are provided spaced opposite respective ends of a tubular core for maintaining proper position of the web roll carried thereby. The method contemplates doffing the core of the cloth roll by utilizing a vertically movable roll for tightening the belt while at the same time lowering one of a pair of spaced rolls supporting the cradle so.
