ABSTRACT:
In a winder for winding webs from a bag-making machine into rolls, a winding turret mounts four winding spindles, each having a web-winding portion and a pulley-mounting portion, which mounts a conjointly rotatable pulley and an independently rotatable pulley. A first timing belt and a second timing belt are arranged to be independently driven. The winding turret is indexable so that, in any indexed position, a first timing belt interengages the conjointly rotatable pulley mounted on the given winding spindle and interengages the independently rotatable pulley mounted on the next winding spindle and a second timing belt interengages the independently rotatable pulley mounted on the given winding spindle and interengages the conjointly rotatable pulley mounted on the next winding spindle. The rotational speeds of a motor driving a given winding spindle, whichever is being used to complete winding of a roll, and the rotational speed of a motor driving a web conveyor are measured. The motor driving the same winding spindle is adjusted so as to maintain a generally constant winding tension on a web being wound. A pair of infeeding rollers and a pair of separating rollers are operated so as to apply a generally constant winding tension to a web, except during intervals during which the surface speed of the separating rollers exceeds the surface speed of the infeeding rollers so as to separate the web at cross perforations.
