STRAPPING ARRANGEMENT
Various embodiments of the present disclosure are directed to a mobile strapping device for wrapping material to be packed with a strap. The device includes a tensioning wheel and a tensioning plate, at least one of which is mounted on a pivotable rocker. The strapping device includes a motor operatively coupleable to the tensioning wheel to rotate the tensioning wheel and to the rocker to pivot the rocker. The strapping device includes an actuating device actuatable to switch the state of gearing from operatively coupling the motor to the tensioning wheel to operatively coupling the motor to the rocker.

(2) at least one of the tensioning wheel and the tensioning plate is arranged on the rocker;
a motor operatively coupled to the rocker and configured to pivot the rocker about a rocker axis to change a spacing between the tensioning wheel and the tensioning plate;
a connecting device configured to connect to one another two regions of the loop of the strapping band situated one atop the other; and
an actuating device actuatable to cause the motor to drive the tensioning wheel, cause the connecting device to transfer from a rest position into a working position, connect the two regions of the loop of strapping band, and drive the rocker to generate the spacing between the tensioning wheel and the tensioning plate.
32 : The strapping apparatus of claim 31 , wherein the actuating device is the only actuating device configured to cause the motor to operate.
33 : The strapping apparatus of claim 31 , wherein the actuating device is actuatable to cause multiple functions to be performed.
34 : The strapping apparatus of claim 33 , wherein different quantities of successive actuations of the actuating device cause performance of different functions.
35 : The strapping apparatus of claim 31 , which includes a second actuating device actuatable to actuatable to trigger at least one of the tensioning process and a connecting process for connecting the two regions of the loop of the strapping band and a third actuating device actuatable to generate the spacing between the tensioning wheel and the tensioning plate.
