Abstract: A heat bond seaming tape has a base formed of a strip of paper or paper-like material. A strip of an open mesh material is adhered to the base strip and is disposed in substantially symmetrical, overlying relation thereto. A plurality of spaced, transversely disposed, rigid bracing members are sandwiched between the mesh strip and base strip or in the alternative are secured on top of the mesh strip. A thermoplastic adhesive overlies the open mesh strip and the bracing members for adhering the strip and bracing members to the backs of adjacent carpet edges, so that a seam defined by said adjacent carpet edges, will lie flat in response to the provision of said seam tape, due to the rigid bracing members extending generally transversely across the carpet seam.
