    Abstract: Described are methods of making a carpet by (a) providing a primary backing material having a front side and a back side, (b) tufting a yarn into the primary backing material to produce a carpet pile on the front side of the primary backing material and loops of the yarn on the back side of the primary backing material, (c) applying by slot coating a layer of a first melted coating composition onto the back side of the tufted primary backing material, (d) applying by slot coating a layer of a second melted coating composition onto the coating applied in step (c) thereby fixing the loops of the yarn to the primary backing material, and (e) applying and pressing a secondary backing onto the slot coated tackifying resin layers and pressing it to join the first and second tackifying resins and the primary backing and secondary backing and yarn loops together to form a carpet.
