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.
Claims10
A tensioning- and friction welding apparatus for a band formed of thermoplastic material and strapped about an article, comprising:
- a counter-clamping jaw;
- a displaceable-welding clamping jaw for both tensioning and welding the band;
- an inclined drive lever for driving the welding-clamping jaw to-and-fro relative to the counter-clamping jaw;
- return movement-blocking means for blocking return movement of the band;
- said counter-clamping jaw and said welding-clamping jaw cooperating to engage therebetween the ends of the band clamped between said jaws;
- said return movement-blocking means engaging with the ends of said band;
- said counter-clamping jaw and said welding-clamping jaw tensioning the band and after reaching a predetermined band tension welding said band ends to one another;
- means for locking the counter-clamping jaw in a work position;
- and
- means for unlocking said counter-clamping jaw from said work position and for enabling displacing the same in the direction of the tension applied to the band.
