ABSTRACT:
A baseplate for a carpet seaming iron of the kind used for making a face seam with hot melt adhesive tape has the underside of the base plate formed with a forward, flat surface and a rearward, ribbed surface. The underside also has a longitudinally extending center groove shaped to form a raised bead of molten adhesive at the outlet end of the iron for coating the side edges of the carpet backings with hot melt adhesive. The forward, flat surface provides maximum contact for heating of the hot melt adhesive; and the rearward, ribbed surface meters the molten adhesive evenly over the full width of the tape. The forward ends of the ribs are longitudinally offset so as to form a V shape which helps to funnel molten adhesive both into the channels between the ribs and into the center groove at the apex of the V as the iron is moved along the tape.
