bent摘要：Apparatus for producing tufted carpet by precutting yarn into individual tufts, and pressing the tufts into an adhesive coating on a backing material. Individual yarns are lectably clamped on a sliding bed, and the sliding bed is moved forwardly to a tufting position. Forward movement of the bed withdraws the yarns and cuts the withdrawn yarns to desired length. The yarns are then unclamped, and a tufting bar pass through aligned condary and primary tufting slots to press the cut yarns against the backing material. The yarns are supplied through a yarn pattern head having a number of yarn bars individually and lectably positionable to vary the tufting pattern in any predetermined manner.
