Bundling tools are known which use tying tapes and with vdchen by hand the tape sections under the jumper wire bundle are placed, the ends of which are gripped by pliers, lashed together, flat side to flat side pressed together and were glued, glued or welded to one another while maintaining the bundle pull, whereupon the protruding part was separated Material takes place. In other known designs, the binding tape is inserted into the jaws of a pair of pliers by hand, of the pliers while pressing the loose jumper wires together pressed against the bundle and welded to it.

If a version has already been registered, the jumper wire will be j

the bundle is gripped by a pair of pliers, which is designed as a guide for a machine-fed binding tape, and which the binding tape hemsftihrt the less bundle - it is welded and un-tightened to form a bundle ring and with which the bundle ]

ring is separated from the binding tape.

It was not previously possible to process binding twine with these known or already proposed designs, since Such Y / tools cause the weld to be welded by pressing the setting means on top of one another, which in the case of one, has a round cross-section exhibiting binding twine to none . Eündelring leads. Should be used when setting binding material with round Cross-section, i.e. binding twine, are used, so far such a binding twine could only be processed manually.
