ABSTRACT:
A system for enveloping items, such as collections of rolls, in plastic film for later downstream package completion. The film, which is in the form of an elongated sheet, is continuously shaped into a tube about a forming apparatus having an orifice extending across the path of travel of the items being packaged. A pair of segmented conveyors located on opposite sides of the path of travel of the items convey the items into the tube. The conveyors conform to the shape of the orifice of the forming apparatus. Another downstream pair of conveyors conveys the tube and items to downstream sealing apparatus. The second pair of conveyors each have segments which can be retracted so that forming apparatus of different sizes can be employed to form packages of different dimensions.
