Abstract

The invention relates to a banding device (01) comprising a binding part (06), by means of which the band conveyed from a supply part (03) can be shaped into a loop around the stack to be banded. In order to weld the loop in the overlapping region, a sonotrode (69) is provided, which in the inactive state can also be used as a clamping element and/or which can be set by a drive that is independent of the cutting (47) or clamping apparatuses (46). A banding station comprises several banding devices (01) adjacent to each other and can be loadable or loaded with a stack that is several banding devices (01) wide in order to band the stack multiple times. During the strapping, the sonotrode (69) is placed against the band overlap before the band is cut and/or while still in the inactive state. In order to increase the throughput, a stack that is several product sections wide is fed into a banding station and then is simultaneously banded multiple times.
