Device for Tensioning and Closing Hoops

The device in accordance with the invention serves to tension and close strapping bands for packaging and suchlike. It has a band channel open longitudinally on one side in the longitudinal direction of the strapping band, a band tensioning device acting in the area of the band channel and a closing device which joins the band ends of the strapping bands lying on top of each other in a tensioned state in the band channel. In order to ensure that strapping bands of different widths to be processed with the device are always processed with the correct tensioning rate, band tension, welding time, holding time and/or other band closing parameters in each case, the device is provided in accordance with the invention with a sensor device directly or indirectly recording the width of the inserted strapping band and a processing and adjusting unit interacting therewith, with which the band closing parameters of the device are automatically adjusted as a function of the band width determined by the sensor device. The sensor device is preferably arranged on a band stop which laterally guides the band ends of the strapping band in the band channel.
