ABSTRACT:
A sleeving system consists of a sleeve forming mechanism for constructing a sleeve from a web of material and a series of pairs of prongs mounted to a pivoting turret mechanism. The prongs are moved to a collapsed position, where a partially opened sleeve is positioned over the collapsed prongs and clamped to one of the prongs. The prongs are pivoted to an inserting station, and are moved apart to open the sleeve at the inserting station. A compressed stack of articles, such as paper towels, is provided to the inserting station, and is inserted by an inserting mechanism into the space between the prongs, and therefore into the opened sleeve. The prongs are then pivoted to a removal station, where a removing mechanism functions to remove the stack from between the prongs and to simultaneously draw the sleeve off of the prongs. The stack undergoes decompression as it emerges from between the prongs, to expand into engagement with the sleeve. The removing mechanism deposits the sleeved stack of articles onto a discharge conveyor. Several sets of prongs are mounted to the turret mechanism, which provides continuous indexing movement of the prongs between the sleeving, inserting and removal stations of the system.
