i. Abstract An automatic bundle-tying tool is disclosed which is distinguished from the prior art by having a compact housing with a pair of curved pincer-shaped jaws, one of which pivots outward to accommodate a bundle of wires or similar elongated objects, and then pivots inward to abut the other, fixed jaw. Plastic tying tape drawn from a storage spool is fed around a tape guide groove formed on the internal surface of each of the mating jaws, encircling the bundle. A pair of thin tapered anvils clamp the overlapped tape against the tip of an ultrasonic welding transducer, and a reverse feed mechanism draws the tape tight around the bundle while slack tape is re-wound on the storage spool by a resilient spring biased spool hub. After ultrasonic welding, automatic spring-driven linkages unclamp and withdraw the anvils, sever the tied bundle from the tape supply and open the movable jaw to release the tied bundle. A preferred embodiment is lightweight, portable and easy to operate. ii. The subject matter of my invention disclosure entitled Improvements to Ultrasonic Tie Wrapper (Wire) filed in the United States Patent and Trademark Office June 24, 1981 as Disclosure Document No. 100860 forms the basis for portions of the subject matter disclosed and claimed herein.
