ABSTRACT:
A strapping tool for tensioning and shearing strap has a tensioning wheel, a ratchet wheel means associated with the tensioning wheel, and a pawl adapted to engage the ratchet wheel means when the tensioning wheel is rotated in a direction opposite to the tensioning direction. When the pawl is engaged, the ratchet wheel drives a single stroke cut-off mechanism. A latch means is provided to place the pawl into engagement with the ratchet wheel. A pawl positioning means connects the latch means and the pawl, and releases the pawl from engagement with the ratchet wheel means as a cut-off stroke is executed. The strapping tool is further provided with a cutting block which has a chamfer along the cutting edge of the block so that the edge of the cut strap is bent downwardly upon being cut, and wear on the cutting edge is minimized as the strap is tensioned.
