ABSTRACT:
A system and process for sealing collections of rolls in a bundle. The rolls, which can be multiply packaged rolls or individually packaged or unpackaged rolls, are accumulated and conveyed until they are aligned and then collected in a group. Successive groups are then inserted in a tube of film which is severed and sealed about each group to complete a bundle. The sealing system includes at least two sealing axes, with each axis having at least one die set. The axes are synchronized and individually driven at variable velocities during their paths of travel.
