摘要：
A carpet seaming apparatus includes an elongated bonding tape having an electrical resistance circuit with contacts at the edge of the tape mounted on the face thereof with a hot melt adhesive in the form of elongated beads running the length of the tape that melts in response to electrical current in the resistive conductors. A tool having spaced apart electrical contacts for engaging the contacts adjacent the edges of the tape inducing an electrical current therein for heating and melting the hot melt adhesive.
