摘要： The heat sealing wire (26) of an impulse heat sealer (10) is held against an operating face of a support bar by an insulating fabric (34) which is draped over the wire and secured in a slot (24) formed in the support bar (18). The securing drape of fabric allows unrestricted expansion and contraction of the hot wire. Also if the slot lies in a curved plane which extends perpendicular to the plane of the support bar operating face, the drape of insulating fabric and consequently the sealing wire follow the same curve so the heat sealer can make seals of a non-linear configuration.

摘要： Bag making apparatus and method for forming a handle opening (30) in a thermoplastic food packaging shrink bag includes cold cutting and hot cutting operations as well as heat-sealing the two plies together by a welded seam (38) circumscribing the entire cut, to form a handle which, on heat shrinking the bag, is strong and has an enhanced appearance.
