Abstract: A belt splicing tool for thermally joining first and second ends of thermoplastic belts. The tool includes a position control means and first and second clamping mechanisms cooperatively engaged and diametrically opposed along a longitudinal axis. The first clamping mechanism holds a first end section of a belt and the second clamping mechanism holds a second end section of a belt. The position control means repositions the clamping mechanisms relative to one another along the longitudinal axis between a first position where the longitudinal spacing between the clamping mechanisms is minimized, and a second position where the longitudinal spacing between the clamping mechanisms is maximized. The tool retains and aligns both belt ends in an opposed abutting relationship while permitting longitudinal movement of the belt ends relative to one another.
