Abstract
For enclosing a stack of goods in a sheath of a heat-shrinkable plastic material, the plastic material is supplied in the form of a flattened tube pleated along its longitudinal edges. Initially the tube is gradually opened by spreading its contacting flattened surfaces and pleated edges and then individual spaced pleated portions along each edge are gripped by pairs of conveyors for pulling each of the pleated edges in an opposite direction so that the tube is opened into a generally rectangular shape. After passing downwardly from the conveyors, the lower end of the opened tube is gripped interiorly and the gripping members are moved laterally outwardly stretching the tube to a desired extent and then the gripping members pull the tube downwardly until the stack of goods is partially enclosed and the tube is spaced outwardly from contact with the goods. As the downward movement of the tube is interrupted, a section of the tube is severed and welded closed at its upper end. The severed section is displaced laterally from engagement with the conveyors and the downward pulling action is then continued until the section of tube encloses the stack of goods.
