ABSTRACT:
A bundling strap specially constructed to be ultrasonically welded to form a locked loop about a plurality of articles to be bundled and a method for carrying out the welding. A central strap body is formed with at least one marginal strip joined to the central body portion along a marginal edge thereof, the marginal strip carrying an energy directing means to concentrate applied ultrasonic energy and produce a bond between such energy directing means and the overlying marginal strip. A method whereby the anvil remains outside of the strap loop permits the loop to be formed and the anvil to be easily later removed without affecting bundle tension.
