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).
