Abstract
A method of positioning and guiding two edges of thin sheet metal in such a manner that the edges are urged into overlapping relationship with each other under pressure and are continuously moved in a longitudinal direction while converging toward each other. The edges of the sheet metal are forced out of overlapping relationship against the pressure so that such edges are in abutting relationship with each other at the point of convergence at which time such edges are welded together by a source of heat.
