ABSTRACT:
A strapping tool for tensioning a strap loop around an article and for crimping or notching a push-type seal around the overlapping strap portions is provided with a frame, an arm pivotally mounted on the frame for pivoting movement in a first direction and in a second, opposite direction, an abutment nose on the arm for engaging the seal during tensioning, a spring biasing the arm in the first direction during tensioning, a motor-driven tension wheel for pulling one of the overlapping strap portions through the seal to tension the loop whereby the tension reaction urges the abutment nose against the seal and, at a predetermined tension level, causes the arm to overcome the spring and pivot relative to the frame in the second direction. A jaw assembly is provided for crimping or notching the seal and a control means is provided for actuating the jaw assembly in response to the movement of the arm in the second direction at the predetermined tension level.
