Tufting apparatus includes servomotors (18, 20) driving front and back yarn feed rolls (R) for feeding yarns (Y) to the needles (N) of the front and back needle bars (10, 12), respectively. Incremental servomotor control for each stitch enables a height differential between immediately adjacent stitches in excess of 3/32 inch (2,38 mm). By providing yarns of multiple colors and textures, a variety of patterns and textured surface effects are provided in the surface of the tufted pile fabric.

Une commande incrémentielle de servomoteur pour chaque point permet d'obtenir un différentiel de hauteur entre les points immédiatement adjacents supérieur à 3/32 pouce (2,38 mm). En utilisant des fils de couleurs et de textures multiples, on peut obtenir une variété de motifs et d'effets de surface texturés à la surface d'un tissu à poils tufté.
