standard primary backing material it should be clearly understood that when practising the preferred embodiment of the present invention the tension on the tufting machine is adjusted so that the foam compound is compressed beneath the loop backs to produce a relatively smooth back for the tufted product after tufting the carpet product is complete for many applications it has been found that the foam compound grips the face yarn as it passes through the foam compound to such a significant degree that the tufted product has utility in many floor covering applications when the tufted product is glued down to a floor surface as is often done with indoor outdoor carpet materials the glue material will both secure the carpet product to the floor surface and also further secure the face yarn in the backing material in one alternative embodiment of the present invention the tufted backing is passed through a coating operation where a very thin layer of adhesive compound is applied to the loop backs since the loop backs have compressed the foam compound and therefore present a relatively smooth surface with the tops of the loop backs at substantially the same level as the uncompressed foam compound between adjacent loop backs the adhesive material may be applied to fill the depressions around the loop backs where the adhesive is most effective and may be doctored off the adjacent foam compound surfaces where it has relatively little effect the thin back coat layer of adhesive compound may range in weight from 0 1 oz per square yard to 8 oz per.
