ABSTRACT:
A method and apparatus are provided for forming a strap loop and securing it about an article. The strap free end is pressed against a guide surface and moved in a path to form a primary strap loop while permitting the primary strap loop to twist off of the guide surface. With the free end of the strap held against further movement, the trailing portion of the strap is fed to expand the loop to a predetermined larger size. The article is inserted in the loop and the trailing portion of the strap is withdrawn to tighten the loop about the package. The trailing portion of the strap is severed from the tightened strap loop and the overlapping portions of the strap are sealed by a friction-fusion weld.
