A pneumatically powered strapping tool, being modular, comprises a tensioning motor module, a sealing motor module, a sealing mechanism module, and a control valve module. The tensioning motor module comprises a pneumatic tensioning motor arranged to coact with a tensioning mechanism driven by such motor for tensioning two overlapped ends of a steel strap drawn from a supply and wrapped around a load. The sealing motor module comprises a pneumatic sealing motor, which is arranged to drive the sealing mechanism module for sealing the overlapped ends to each other, after the overlapped ends have been tensioned. The control valve module comprises pneumatic control valves for controlling the respective pneumatic motors. The modules and the tensioning means are adapted to be readily assembled and to be readily disassembled without requiring disassembly of any of the modules. |
