Abstract
A method is disclosed for forming, tensioning and sealing a strap loop about a package and then severing the sealed loop from the trailing length of strap. A length of strap is fed in one direction and the strap free end is guided or moved to form a small primary strap loop with the strap free end overlapping a portion of the loop. The strap free end is then restrained while the standing part of the loop is continued to be fed to expand the loop to a larger predetermined diameter. The expanded loop and/or package is then moved so that the package is encircled by the loop, after which the loop is tensioned tight about the package. A joint connection or seal is next made in the loop and the trailing length of strap is severed from the loop.
