Various embodiments of the present disclosure provide a mobile strapping device for strapping packaged products using a loop of wrapping strap. The strapping device includes a tensioning device for applying tension to the strap and a connecting device for connecting two overlapping portions of the strap. The tensioning device includes a rotatable tensioning wheel and a tensioning plate. The tensioning wheel is supported by a rocker that is pivotable to change a distance separating the tensioning wheel and the tensioning plate. The mobile strapping device includes a motor that is operably connectable to the rocker or the tensioning wheel such that the motor causes pivoting of the rocker or rotation of the tensioning wheel when operating in a first direction of rotation. In various embodiments, gearing, including a plurality of planetary gear sets, is used to operatively connect the motor to the rocker and the tensioning wheel.

Various embodiments of the present disclosure provide a strapping tool configured to tension metal strap around a load and, after tensioning, attach overlapping portions of the strap to one another by cutting notches into a seal element positioned around the overlapping portions of the strap and into the overlapping portions of the strap themselves.

A banding machine is disclosed including a band guide, a band drive, a rotary encoder and a controller. The band guide is provided with at least one distance sensor. With the aid of the at least one distance sensor, distances to a packaged good lying within the band guide can be determined. With the aid of the band drive, a band can be inserted into the band guide and retracted. The rotary encoder can be used to detect a retracted length of the band or the differential length, which is the difference between the inserted length and the retracted length of the band. The controller is designed to determine a desired value taking into account the distances determined by means of the at least one distance sensor. The controller is designed to control the band drive in such a way that, during retraction, the band is initially retracted at a first retraction speed and, as soon as the retracted length or the difference length corresponds to the desired value, the band is retracted at a second retraction speed which is lower than the first retraction speed.
