A fully automatic cyclicly operable strapping tool for tensioning a loop of fusible plastic strapping having overlapping and regions about an object and thereafter, when a predetermined degree of tension has been attained in the loop, severing the tensioned loop from the source of strapping and effecting and maintaining interfacial friction between such end regions until fusion welding takes place, after which interfacial pressure is maintained until solidification occurs. |
