Cut pile looper and hook tufting improvement
A tufting machine with a needle bar and looper system provides individual loopers which cooperate with needles of the needle bar selectively between an engage and a disengage configuration whereby when in the engage configuration at least some of the loopers hold yarn directed by the needle through the backing as the needle cycles into and out of the backing to form a first loop having a height of a distance of the looper from the backing, but when in the disengage configuration, the looper is spaced from the yarn so that any loop formed is shorter than the first loop.

Tufting maching and method of tufting
A tufting machine for selectively forming tufts of yarns, including different color or type yarns, for forming patterned tufted articles such as carpets. A series of needles are reciprocated into and out of a backing material being fed through the tufting machine and are engaged by a series of gauge parts so as to pick-up loops of yarns from the needles. The gauge parts will be selectively controlled by activators to extend or retract the gauge parts to positions or elevations sufficient to pick-up or not pick-up loops of yarns from the needles. The feeding of the yarns to the needles further will be controlled to back-rob yarns not picked-up by the gauge parts, while the backing feed will be controlled to enable formation of tufts at an increased rate over the pattern stitch rate for the pattern of the tufted article being formed.

Hook for a tufting machine
A hook (5) for a tufting machine to provide an enhanced J-cut effect. The hook comprises a shank portion (12) via which the hook is connected to the tufting machine, in use, and a working portion (4) extending from the shank portion. The working portion (4) comprises a cutting edge (6) on one side of a lower face of the working portion. A J-cut forming portion is formed at the working portion (4), in that the working portion in the region above the cutting edge has a greater thickness than the thickness of the shank portion (12).

A Presser Foot Module for A Tufting Machine
A presser foot module (50) for a tufting machine. The module has a module body (13) for attachment to a tufting machine and the plurality of fingers (12) extending from the body in a first direction which, in use, is opposite to the direction in which the backing medium (1) is fed through the tufting machine. The module body (13) has a downwardly depending lip (53) defining a presser surface (53A) extending across an end of the body which is adjacent to the interface with the fingers (12). Each finger (12) has an unsupported end opposite to the module body (13) so as to provide access to an open gap between adjacent fingers in a direction opposite to the first direction.

Variable or multi-gauge cut pile tufting with backing shifting
A shiftable backing feed or shiftable needle assembly is utilized with a tufting machine having reciprocating needles and gauge parts for seizing or cutting yarns wherein yarn placement patterns can be utilized to tuft at different gauge densities while maintaining the same pattern sizes and appearance, and gauge parts are adapted for high density stitching.
Multi height looper and backing shifter
A shiftable backing feed is utilized with a tufting machine having reciprocating needles and gauge parts for seizing yarns at a plurality of fixed heights, wherein fabric support apparatus reciprocates in synchronization with the cycles of the needle bar to support the backing during penetration of the backing fabric yet allow backing shifts between stitches.
