Abstract
A carpet seaming iron of the kind used for making face seams with hot melt adhesive tapes forms a raised center bead in the molten adhesive produced behind the iron. The center bead is of a sufficient height and stiffness to coat the side edges of the carpet backings with hot melt adhesive as the undersides of the carpet backings are lowered onto the layer of molten adhesive. The side edges of the backings are locked directly together through the adhesive interposed between the side edges.
