ABSTRACT:
An apparatus for positioning and guiding the opposed edges of sheet metal so that the edges thereof are progressively moved into substantially intimate relationship with one another so that such edges may be subsequently welded to form a seam. The apparatus includes three replaceable guide elements that cooperatively form opposed and relatively converging guide channels which progressively direct the sheet metal edges into intimate relationship and maintain such relationship as the sheet metal is introduced into a seam welding station.
