ABSTRACT:
An apparatus for strapping packages with a band (7) made of weldable plastic comprises a band-supply unit, a band-transporting and -tensioning unit, a closure unit, which is provided as a separate unit and has an abutment plate, and a band-guidance unit and has at least one band clamp (15) with a pivotably mounted clamping part (10). The band clamp (15) is formed by a specific recessed section (14) of the abutment plate (5) and the clamping part (10), a curved operative surface (40) being provided on the clamping part, and the band clamp (15) being self-locking. Selecting the clamping angle W for the band (7) between the clamping part (10) and recessed section (14) to be as large as possible means that it is easier to release the band clamp when the band is tensioned. The apparatus makes it possible for strapping bands to be applied, even with high tensioning, without slipping during the closure operation.
