  • Patent number: 6421939
    Abstract: A carpet seaming iron is provided for heating adhesive seaming tape without direct contact to the adhesive. The carpet seaming iron has an outer housing forming a cavity therein and a handle with an open end leading to a passageway to the cavity. A heating element is located within the cavity and spaced from a lower base plate. The base plate has apertures therethrough. An electrically operated fan is disposed in the cavity, between the open end of the handle and the heating element. The fan draws ambient atmospheric air through the open end and directs the air past the heating element and through the apertures in the base plate toward the adhesive seaming tape. The air is heated by the heating element so that the air melts the adhesive. The base plate is attached to rollers or ski devices to space the base plate from the adhesive tape.
