Abstract
Abstract Carpet material made up of a needled deposited layer of nonwoven fibers. The deposited layer may be fused on either the upper or the lower surface or both, and a layer of a substantially resilient material is attached to the lower surface. An additional layer of non-woven fiber may be placed on top of the deposited layer, and a layer of tacky adhesive covered by a peelable sheet may be applied to the bottom of the resilient material.
