Abstract

Disclosed is a device for tensioning and sealing tightening straps of plastics for package tightenings, in which the superposed strap ends are received in a strap channel which is essentially open at a longitudinal outer side and the two faces. The strap channel has a strap edge guide at its longitudinal inner side for the inner edges of the tightening strap. A tensioning device is arranged in the front region of the device, and a sealing device is arranged in the rear region. So as to compensate for the forces acting outwardly on the upper strap end due to the irregular deformations of the upper strap end during the tensioning process by the tensioning roller of the tensioning device which is mounted in a floating manner, the strap edge guide is arranged obliquely to the tensioning direction of the tensioning roller and projects further into the strap channel in the vicinity of the strap sealing device than in the region of the tensioning device.
