Abstract
A tensioning unit for a strapping machine serves for tensioning and sealing a band guided around an item to be strapped. It has a tensioning head and housing. The tensioning head includes a tensioning device and clamping and sealing subassembly. Toward the end of a tensioning operation, the head can be displaced relative to the housing in a band-running direction, counter to tensioning direction. Also provided in the housing is a band guide arranged downstream of the clamping and sealing member, in the band-running direction, subdivided into front and rear band-guide parts. In this case, only the front band-guide part can be displaced, together with the tensioning head, relative to the housing, whereas the rear band-guide is moved transversely to the band-running direction by the front band-guide part, which is moved in the band-running direction B, counter to a spring force.
