Artificial turf and associated devices and methods for making same

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.

TUFTING MACHINE AND METHOD OF TUFTING
20210246589 · 2021-08-12 ·

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.

Variable stroke drive system for tufting machine
10995439 · 2021-05-04 · ·

A variable stroke drive system for a tufting machine includes a series of drive assemblies mounted along the frame of the tufting machine. Primary drive shafts extend through the drive assemblies and are each driven by a drive motor. A series of first drive members are mounted to the primary drive shafts and are linked to associated second drive members such that the driving of the first drive members by the primary drive shafts in turn drives the second drive members. Cam arms are connected to the second drive members and to rocker arms to which push rods are mounted, the cam arms being vertically reciprocated by the rotational movement of the second drive members so as to drive the reciprocation of the push rods, and thus the needle bar(s) connected thereto along a desired stroke or reciprocating path of travel. Controlling the rate at which the primary drive shafts are driven enables control of the stroke of the needle bar(s).

A Tufting Machine
20210040664 · 2021-02-11 ·

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).
