Tufting machine and method of tufting
11708654 · 2023-07-25 · ·

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.

Tufting machine
11492739 · 2022-11-08 · ·

A tufting machine comprising a plurality of needle holders (11) associated with a needle bar (5) and slidably supported in a frame for reciprocation in a needle reciprocation direction. A respective needle (10) is attached to each needle holder (11), each needle holder having an engagement portion. The needle bar (5) has means (7, 13) for selectively latching with the engagement portion of each selected needle holder so as to selectively drive latched needle holders in the needle reciprocation direction. A stop bar (21) is positioned to limit the upward movement of the needle holders (11). At least one magnet (20) retains non-latched needle holders in its uppermost position as the needle bar is reciprocated. The magnets (20) are embedded in the stop bar (21). The machine further comprises a cushioning member (27) attached to the magnet (20) and facing the top of each needle holder (11).

A lightweight needlebar drive is provided that vertically reciprocates a needlebar by driven feet mounted to the lower ends of pushrods, where the feet are laterally positionable by virtue of a plurality of stub shafts passing through and received in bearings on adjacent brackets connected to the needlebar.

Individual needle control tufting machine

A tufting machine and method for operating a tufting machine operating a needle selection mechanism based on pattern data by selecting a needle with yarn required for the pattern such that the selected needle is driven by a needle bar through the backing medium, to form a tuft while a needle that is not required for the pattern is not selected by the needle selection mechanism. Yarn is fed via a yarn feed mechanism comprising a plurality of actively driven yarn drives each driving a respective yarn to a respective needle, the yarn drives being at a location between a yarn creel and the needle. The method being characterised by operating the yarn feed mechanism to deliver at least 70% of the yarn required for a tuft as the needle moves from top dead center to bottom dead center.
