Backing fabric shifting relative to needles and gauge parts for seizing yarns is utilized in a tufting machine having needle plate fingers or backing support that reciprocates in synchronization with the cycles of the needles to support the backing during penetration of the backing fabric while allowing backing shifts between stitches.

Backing fabric shifting relative to needles and gauge parts for seizing yarns is utilized in a tufting machine having needle plate fingers or backing support that reciprocates in synchronization with the cycles of the needles to support the backing during penetration of the backing fabric while allowing backing shifts between stitches.

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 move 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 pull back the 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.

A system and method for tufting sculptured and multiple pile height patterned articles, including controlling placement of yarns fed to the needles of the tufting machine by a yarn feed mechanism to form varying patterns includes a backing support over which the backing is fed, and which lifts/and biases the backing to a raised position. As the backing material is fed through the tufting machine, a series of loopers or hooks engage and pick loops of yarns from the needles. The yarn feed mechanism will be controlled to create a tension in selected loops of yarns, to cause the backing material to be pulled against the bias or spring force applied by the backing support toward the needle plate of the tufting machine to create tufts of different pile heights.

A method of preparing a tufting process for tufting a fabric, preferably carpet, having regions (14, 16, 18) of different color appearance by using at least two different kinds of yarns, yarns of different kinds of yarns (b, w) alternately following each other in a needle bar longitudinal direction of a needle bar of a tufting machine, comprises the steps of: a) defining a predetermined number of color mixing values, b) assigning with each color mixing value a color-related tufting aspect instruction, c) providing a color pattern representation (11) of the fabric to be tufted comprising a plurality of color regions (14, 16, 18), d) assigning with each color region (14, 16, 18) one of the color mixing values.

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.
