Abstract: An improved apparatus is disclosed in which a tensioned plastic strap loop is placed about an article. The invention includes a laterally adjustable forward guide. The guide is pivotally connected to the feed nip of the drive mechanism so as to provide a constant gap between the nip and guide. The rear end of the guide rests upon and moves with the forward gripper. Thus, a guide is provided which minimizes abrasion, can receive straps of different widths, and be easily and quickly cleaned.

Abstract: An improved apparatus is disclosed in which a tensioned plastic strap loop is placed about an article. The invention includes an improved rear guide. The guide is connected to the rear gripper so that it moves with it. The rear guide has a pair of forward and a pair of rear guide members. The forward members are shorter than the rear ones. The forward seal guide members are located so that they are in the middle of the seal region and thus prevent lateral movement of the overlapped strap ends when the heat seal blade is inserted and withdrawn from between them.
