  • Publication number: 20030015522
    Abstract: An electrically activated hot-melt adhesive tape for adhesively joining objects such as adjacent sections of carpet. The tape has a base which is typically paper, and an electrically conductive ink-like material is sprayed or printed on the base to form a thin central heating section, and thicker and hence lower-resistance conductive strips extending along opposite edges of the heating section. Scrim supporting beads of hot-melt adhesive is secured over the heating section. Alternatively, the heating section and conductive strips, which may be segmented, are applied to an underside of the base, and the scrim and adhesive beads to the opposite side of the base. An activating tool has extending electrodes which electrically contact the spaced-apart conductive strips to pass a current through the heating section to melt the adhesive beads in preparation for application to the objects to be joined.

  • Patent number: 5294284
    Abstract: A heat shield for the upper surface of a carpet seaming tape iron, preferably formed of polytetrafluorethylene or other heat resistant synthetic material, covers only so much of the upper surface of the iron as is needed to assure that the carpet backing coming into contact with the iron will not be overheated. Since some heating of the carpet backing is desirable in the hot melt carpet seaming tape operation, the forward and rear surfaces of the iron are left at least partially exposed so that the carpet backing will have some direct contact with the hot metal heat transferring surface at the top of the iron's body. The heat shield is contoured so as to fit closely down against the surfaces of the carpet seaming tape iron, avoiding any unnecessary deflection of the carpet edges during the seaming operation and providing an integral feel to the assembly. Assembly may be as original equipment or as a retrofittable addition to an iron.
