Abstract
A hot melt carpet seaming tape and a method of installation are effective to minimize seam peaking at carpet joints. A seaming iron used in the installation has a grooved base plate and connected liquid channels which accomplish seam welding of carpet backings at the seam. As the two carpet edges come together behind the iron, the backings are seam welded by the liquid adhesive in a butt joint, adding significant strength to the seam in the carpet. The carpet seaming tape has a narrow hot melt adhesive strip, preferably less than two inches wide. When the carpet seaming tape is used in conjunction with seam welding (seam sealing), with hot melt adhesive applied between the edges of the carpet backings, the assembled carpeting when stretched will not tend to peak significantly at the seam.
