An apparatus (31) and a method are disclosed for temporarily separating multiple webs (51,53) while performing an operation (123,125,133) thereon, including the feeding of multiple webs (51,53), the provision of a retractable web separator (68) for temporarily separating the webs, the performance of an operation (123,125,133)) upon the webs, the provision of a gripping device (65) for gripping the webs and assisting in moving the webs (51,53) along a predetermined path (83), and the provision of a sealing device (71) for sealing the webs together to form a package seal (73). The retractable separators (68) are mounted on a conveyor (83) and each separator (68) in turn temporarily separates the webs (51,53), for insertion of a port (45), fitting or the like, whereupon the separator (68) may be retracted and the port (45) may be sealed into the packages (41) being manufactured. The preferred separator (68) has a shaped head (170) on the end of a reciprocating shaft (158). The head (170) may be enlarged and may have a tapered end (171) for insertion between the webs (51,53). |
