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.

Abstract: The device according to the invention for tensioning and sealing of strapping bands has a band abutment (24) for the inner band edges (27) of the band ends (20, 21) to be welded together, which is provided with a band width adjustment device (28) according to the invention, with the help of which the band abutment adjusts the band abutment transversely to the longitudinal direction of the strapping band in the housing and that the device can be adjusted to strapping having with different widths without any reconstruction measures (see FIG. 3).

Abstract: The device according to the invention for tensioning and sealing plastic strapping bands for packages has a housing (11), a band channel (14) extending in the longitudinal direction of the strapping band (12), which is open on one side and which receives the band ends (19,20), which channel is limited on one of its side by a tensioning plate (16) and on its other side by a tensioning wheel (18) provided with a profiling, whereby the tensioning wheel and the tensioning plate can be abutted relatively to one another.

Abstract: The invention relates to a tensioning device for tightening strapping bands. When a tensioning motor runs forwards in the tensioning direction, a tensioning wheel is automatically pivoted against an abutment in the opposite direction. Once the tensioning process is complete, said tensioning wheel is pivoted back out of the tensioning position and into the starting position by running the tensioning motor backwards.

Abstract: The invention relates to a tensioning device (10) for tightening strapping bands. When a tensioning motor (20) runs forwards (20) in the tensioning direction (29), a tensioning wheel (21) is automatically pivoted against an abutment (24) in the opposite direction (30). Once the tensioning process is complete, said tensioning wheel is pivoted back out of the tensioning position and into the starting position by running the tensioning motor (20) backwards.
