Abstract: The invention relates to a tufting unit for a tufting machine, wherein a yarn transport gripper positions yarn strands which after cutting thereof are used by insertion elements. Furthermore, the invention relates to a tufting unit having such a tufting machine.

Abstract: Implementations herein describe an artificial turf having a backing layer and a plurality of rows of individual tufts tufted into the backing layer. Each tuft comprises at least three yarns per tuft and each one of the at least three yarns varies in at least one of material, color, texture, denier and cross-section. Each row of individual tufts is substantially similar to each adjacent tufted row and adjacent tufts on a given row are spaced apart at a predetermined gauge.

Abstract: A novel method of tufting carpets is provided to allow the use of the same sequence of colored yarns on front and rear staggered needle bars to yield sufficient gauge stitch density to provide for a solid appearance of any of the selected colors et, and utilizing optimized tacking of rear yarns to minimize loose yarn on the backing.

Abstract: A hollow needle tufting apparatus is provided with swivel mounted knives and an improved needle design directed to improve cutting efficiency and the life of the hollow needles and associated knives.

Abstract: A sewing apparatus includes a hollow needle that can pass through a work cloth, and a needle cover that has a passing hole through which the needle passes and holds the work cloth. The needle cover functions as a presser foot and holds at least a part of a thread between a previous stitch point where a stitch has been previously made and a succeeding stitch point where a stitch is to be currently made. Accordingly, sewing can be performed on the workpiece without use of a lower thread.

Abstract: A pullback mechanism is provided that includes base block, a clamping retainer, and a sliding retainer. The clamping retainer preferably includes a clamping block and a mechanism for tightening the clamping block against the base block. The sliding retainer preferably includes a retainer carriage on which is mounted a clamping retainer and a mechanism for tightening the clamping retainer against the retainer carriage. In one preferred embodiment, the sliding retainer is mounted on a guide rail that is fixed to the base block. A pullback line attached at one end to the retainer carriage of the sliding retainer and at a second end to a movement imparting mechanism. A control unit controls the operation of the movement imparting mechanism to impart movement to the pullback line. In a further embodiment, a lead screw is provided on the base block and the sliding retainer is moveable coupled to the lead screw via a threaded mounting hole.
