Abstract
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.
