Abstract
A method of laying carpet to avoid seam peaking, the method employing an enhanced width seaming tape spanning the abutting edges of the carpet forming the seam. The tape has a hot melt adhesive on the upper surface facing the carpet backing. An enhanced width carpet seaming iron is employed to melt the adhesive and to provide a bond between the tape and the carpet backing. In an alternative embodiment, the tape is made in three segments with one of them applied spanning the seam and the other two in flanking positions along either side of the seam spanning tape. In another embodiment the seaming tape is constructed with a composite modulus of elasticity which varies across the width of the tape. The invention also includes several embodiments of the enhanced width seaming iron for application of the tape to the carpet seam.
