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.

A bundling strap of the type whose ends are ultrasonically welded together to form a locked loop about a plurality of articles to be bundled the improvement comprising:
- a central body portion having a first edge and a second edge;
- at least one marginal strip coupled to one of said first and second edges;
- said marginal strip having an interior surface and an exterior surface, said exterior surface being positioned adjacent articles to be bundled;
- at least one energy directing means, one for each marginal strip and coupled to its associated marginal strip;
- said energy directing means contacting said marginal strip when a portion of said strip overlies a further portion of said strap after same has been looped about a plurality of articles to be bundled;
- said energy directing means forming a joint with said overlying marginal strip when said strap is subjected to ultrasonic welding energy.
