Abstract
An apparatus and method for automatically unloading narrow rolls of web formed by a cutting machine while preserving the order in which the narrow rolls of web were formed. The apparatus includes a feed station, a winding station, a cutting station and an unloading station. The feed station distributes a sheet of product in strip form with a relatively large width to the cutting station in which the sheet is split so as to form several narrow strips of web. The winding station includes at least two winding mechanisms on each side of the sheet to wind each narrow strip of web onto a core. The winding shafts are movable from the winding station to the unloading station so that other winding shafts can be moved to and used in the winding station. The rolls of strip product on the winding shaft are transferred to respective reception shafts in the unloading station, the winding shafts and reception shafts generally aligning with one another in the unloading station such that there respective cantilevered, free ends reside adjacent one another.
