Abstract
The specification discloses a two-sided carpet construction and a method for the continuous manufacture thereof. The carpet manufacturing process begins by tufting a carpet yarn into a scrim layer. The process continues up to the point where the bonding material is applied to the carpet scrim to lock the tufts of the carpet fiber in place. In the process disclosed herein, immediately after the bonding material is applied, a piece of carpet material, by which may be similar to the piece just described, or which may be different in color or construction from that just described, is continuously applied in 180.degree. opposed relationship on the top of the bonding material just applied. The carpet construction thus formed is then passed through pressure applying means to firmly force the bonding material into the carpet tufts and carpet scrim to form a continuous piece of two-sided carpet material having approximately half the weight of bonding materials of previous constructions.
