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 tufting machine comprises a needle bar and a needle bar drive mechanism for moving the needle bar towards and away from a backing material passed through a tufting zone by means of a backing material feed mechanism. The machine further comprises at least one controller and a cooling liquid system for cooling at least one controller, the cooling liquid system comprising at least one cooling member having a cooling liquid channel for the passage of a cooling liquid and being in heat transfer contact with at least a part of the electrical components of a controller.

A system and method for forming synthetic/artificial grass or turf products in which a series of tufts of artificial/synthetic grass filaments or yarns are formed in a backing material with various graphic pattern effects being formed therewith. The system generally will include at least one needle bar having at least one row of needles mounted along a tufting zone and reciprocated through the backing to a desired penetration depth, and will present a desired set or group of yarns to a series of pattern pixels or stitch areas. A series of level cut loop loopers or hooks will be aligned with and will engage the needles in order to form tufts of yarns in the backing material. Clips of the level cut loop loopers will be selectively controlled to control the retention of selected ones of the yarns presented at each pattern pixel. The remaining, non-selected yarns generally are not retained at the pattern pixels, and can be formed as lower pile tufts or removed from the backing material.

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.

Yarn injection device for injecting yarn sections into a substrate, wherein the yarn injection device comprises:a yarn storage for holding a number of spools with yarn,a feeding device configured to feed lengths of yarn to an injection unit, the feeding device comprising: ?a number of yarn tubes, each yarn tube defining a yarn channel configured to accommodate a respective yarn, ?a number of cutting devices located being configured to cut a number of yarn sections,the injection unit comprising: ?an injection needle guide defining a number of first passages extending over a vertical distance and a number of second passages extending over a horizontal distance, ?a number of moveable injection needles configured to pass through the first holes of the injection needle guide, wherein yarn sections in the yarn tubes located below the moveable injection needles are injected into the substrate when the moveable injection needles move downward through the injection needle guide, ?at least one needle actuator configured to move the number of moveable injection needles,a fluid flow assembly, wherein at least one fluid communication channel extends between the injection needle guide and the depressurized or pressurized compartment, wherein the fluid flow assembly is configured to create a flow of fluid through each fluid communication channel, each injection needle guide and each yarn tube in order to apply a drag force on the yarns and move the yarns through the second passages in the injection needle guide.

The invention relates to a tufting unit for a tufting machine, wherein a yarn transport gripper positions yarn strands which after cutting thereof are used by insertion elements. Furthermore, the invention relates to a tufting unit having such a tufting machine.

A method of tufting carpet using multiple yarns directed through at least one single needle, if not a plurality of such situations, whereby the needles tuft a carpet having unique specifications. Specifically, the yarns are pre-twisted together, and can be solution dyed and/or of have different twist characteristics, such as selected from the group of high twist, standard twist, low twist, no twist, flat yarns and/or pre-twisted flat yarns.
