Abstract: A tensioning arrangement is provided for applying a tensioning force to a strapping band. The tensioning arrangement includes a guide for the strapping band, a transporting device which can move the strapping band, and a drive for the transporting device, such that a predetermined tensioning force can be applied to the band. The arrangement is developed by a clamping device for fixing a section of the band during a tensioning phase, and by the transporting device, which can move the clamping device and the band section fixed therein, along a path during the tensioning phase for the purpose of applying the tensioning force. The arrangement further includes a device for detecting a parameter value corresponding to the tensioning force. The detecting device is connected to a control device which, when a predetermined limit value is reached, causes the transporting device to stop.

Abstract: A tensioning and sealing apparatus for strapping an object with a band exhibits a tensioning unit (3) for retaining and tensioning two ends of the band which are to be sealed as well as a sealing unit for connecting the two mutually overlapping ends. The tensioning unit (3) has a motor drive (12) and comprises a tensioning shoe (5) and a drivable tensioning wheel (8) which is fastened on a pivotable rocker (6) and is intended for pressing the band against the tensioning shoe (5) and for gripping the same upon rotation. In order to achieve a high overall efficiency of the tensioning drive, the drive motor (12) of the tensioning wheel (8) is arranged coaxially with the tensioning wheel (8) and is connected to the tensioning wheel (8) via a gear mechanism arranged coaxially with the tensioning wheel (8).

Abstract: A tensioning and sealing apparatus for strapping an object (2) with a plastic band (1) includes a housing (3) having a tensioning unit (4) for retaining two ends (6, 7) of the plastic band (1) which are to be sealed and for tensioning the same and having a sealing unit (5) for connecting the two mutually overlapping ends (6, 7). The tensioning unit (4) has a tensioning shoe (10) and a toothed tensioning wheel (13) which is mounted on a pivotable rocker (11), which can be driven via a tensioning shaft (12), and which is intended for pressing the plastic band (1) against the tensioning shoe (10) and for gripping the same upon rotation. The bearing (15) of the pivotable rocker (11) is arranged on the side of the tensioning shoe (10) and behind the latter in the tensioning direction (14), the rocker axis being located between a bearing surface (16) of the tensioning shoe (10) and a base plate (8).
