ABSTRACT:
The invention is directed to a hand supported, hand operated tool for drawing up the loop formed by a self-locking strap about a plurality of articles to be bundled. A slide means translates across a stationary base member bearing at one end pawl means for grasping the strap and along its length finger grips to cause translation of the slide means. An internally confined return spring returns the slide means to an initial position and opens the pawl means. The repetition of the cycle permits the pawl means to grasp the strap at a different location and further translation of the slide means causes further tightening of the strap loop. When the operator determines that sufficient tension exists in the loop, he merely rotates the tool in a clockwise or counterclockwise direction about its longitudinal axis and causes the strap body portion to engage the sharpened sides of the slot in the tool nosepiece causing the strap body portion to be severed.
