A method and apparatus is provided for installing face seamed stretched carpet, wherein the carpet seam is adhesively bonded to the floor or other substrate after stretching to eliminate peaking and profiling. A flexible, tear resistant release liner is used to isolate the adhesive used for bonding the seam to the floor, to prevent bonding prior to stretching of the seamed carpet. Once seaming is complete, the carpet can be stretched and anchored, and the release liner can be easily pulled out from underneath the stretched carpet to expose the adhesive, and the seam can be bonded to the floor simply by applying pressure to the top surface of the seam area along the entire length of the seam. Pressure sensitive type adhesives have been found to be particularly effective for use in this method because they form immediate bonds which enable the carpeting process to proceed without delay, because they form elastic bonds which can accomodate normal shifting of the carpet which occurs with changes in temperature and humidity, and because the bond can be often be reestablished, if it is broken, by simply applying pressure.

A method for installing carpeting in which at least two pieces of carpet, each of which have a pile surface, a backing surface, and an edge, are placed together with their edges abutting and seamed together along the abutting edges using a carpet seaming tape having a carrier with a first and second surface, a layer of hot melt adhesive on said first surface of said carrier, and a layer of pressure sensitive adhesive on said second surface of said carrier, the method comprising the steps laying the carpet pieces on the surface to be carpeted with the backing surface resting on the surface to be carpeted, and the edges abutting each other to form a seam line; approximately centering the carpet seaming tape under said abutting edges along the seam line with the hot melt adhesive layer facing the backing surface and the pressure sensitive adhesive layer facing the surface to be carpeted; melting the hot melt adhesive, and pushing the abutting edges into contact with each other and the hot melt adhesive to form a seam; stretching and anchoring the seamed carpet; and, applying pressure to said pile side of said carpet along said seam to push said pressure sensitive adhesive into contact with said surface to be carpeted, creating a bond between said seam to said surface to be carpeted.
