ABSTRACT:
A strap welding tool and method therefor including a first cam member for moving a sealing gripper toward a first support member to engage and retain tensioned strap disposed therebetween, a second cam member for enabling a vibrator motor to vibrate a welding pad, and a third cam member for moving they welding pad toward a second support member to engage and weld overlapping strap portions disposed therebetween. The tool includes a relatively small base plate to reduce loss of strap tension upon removal of the tool from between strap tensioned about small and irregular loads. A column strength of a strap portion engaged by the vibrating welding pad is reduced by deforming or bending the strap portion, and preferably forming a gap between upper and lower strap portions.
