Abstract
A method and apparatus for heat-seal splicing a trailing end of a first plastic web and a leading end of a second web. The apparatus includes a traverse cylinder actuated pulley system that is disposed transverse to the longitudinal axes of the web ends. The pulley system moves a shuttle that is attached to and that carries a spring biased wheel. In operation, the wheel is moved in either direction across the web ends and between the two ramps. The wheel is spring biased into contact with a heated sealing wire that, in turn, is brought into web sealing contact with sequential portions of web ends as the wheel is moved transversely across the web ends from one webs' side edges to the other webs' side edges and along the sealing wire so as to heat-seal splice the web ends.
