Abstract
A tensioning- and friction welding apparatus for strapping a band formed of thermoplastic material about an article or object, comprising a welding-clamping jaw driven for to-and-fro movement relative to a counter-clamping jaw by means of an inclined drive lever or the like. The jaws engage with the ends of the bands clamped therebetween and which are also engaged by a reverse movement-blocking device, tension such band ends and after reaching a predestined band tension weld the band ends to one another. The counter-clamping jaw is locked in a work position and can be released therefrom and displaced in the tensioning direction.
