Abstract:
Methods of tufting a pattern in a backing material using a plurality of different yarns A, B,.... n that are threaded in the needles of a needle bar in a non-repeating sequence or pattern of yarn sets across the width of the needle bar.
Abstract:
A structure (1) of synthetic turf includes a mat (2), having a sheet-like substrate (3) from which there extend filiform formations (4A, 4B) having at least two different heights (H1, H2). The filiform formations (4A, 4B) are interspersed with respect to one another and are made by using respective yarns (8A, 8B) that are woven separately from one another to the substrate (3) and are cut to different heights. A particulate infill material (11) is arranged between the filiform formations (4A, 4B) to form a filling layer (12), which has a height (H), measured starting from the substrate (3), smaller than or equal to the height (H1) of the filiform formations (4A) of smaller height.
Abstract:
Apparatus for producing pattern tufted goods, such as pattern tufted carpet, produces cut and loop pattern carpet using independent yarn colored pattern and cutting pattern process controllers, colored pattern carpet having differential pile heights, and colored pattern carpet with tight or loose tufts. In addition, an apparatus for making color patterned tufted carpet has a yarn cutting system which more reliably cuts yarn when cut tufts are desired.
Abstract:
There is disclosed a material or fabric making or processing operation involving needle penetration of a fibre, fabric or material layer (12) in which the needle penetration action is controlled by control means (18) by which the needle penetration characteristics can be varied within the penetration action and as between penetration actions.
Abstract:
Apparatus for feeding yarn from a yarn supply to a reciprocating needle of a multi-color pattern carpet tufting apparatus comprises a yarn pullback mechanism mechanically linked to a yarn feeder such that when the yarn feeder moves out of engagement with a driven roller, the yarn pullback mechanism draws the yarn back from the reciprocating needle. When the yarn feeder moves back into engagement with the driven roller, the yarn pullback mechanism shortens the path between the yarn feeder and the reciprocating needle.

Abstract:
A method and apparatus for controlling a yarn feed system for a tufting machine is disclosed. The method involves determining a length of yarn required for a particular stitch, selecting a start time at which additional yarn can be introduced into the yarn feed and selecting a rate of supply of additional yarn into the stitch. The method allows precise control of yarn feed even when extreme forms of sliding needlebar movement are used in a tufting machine.
Abstract:
A deconstructed tufted carpet having an at least partially visible primary backing, In aspects, deconstructed carpet can utilize the primary backing layer as a design element of the overall pattern and styling in order to reduce material use, waste and the ounce weight of the finished carpet and to improve the method of carpet construction. In order to expose the primary backing, at least some yarn can be pulled very low in the pattern areas to expose the primary backing layer. It is contemplated that the primary backing layer can have a color that comprises part of the overall pattern and styling of the carpet.

Abstract:
A yarn feed assembly for a tufting machine. The assembly comprises a plurality of drive shafts (1), a plurality of yarn feed rollers (3), and a clutch assembly (11) to selectively couple a yarn feed roller directly to a drive shaft. The clutch assembly is directly between the yarn feed roller and the drive shaft with no intervening components.
