摘要： A yarn feeder for a tufting machine is compact and simple in structure and is still capable of freely changing the heights of piles formed by each pile yarn on a fabric. The yarn feeder includes yarn feed rolls for feeding pile yarns to a row of needles of the tufting machine, and a brake device provided between the feed rolls and the needles. The brake device includes a grooved plate having grooves arranged in the width direction of the grooved plate and each receiving one of the pile yarns that are being fed from the feed rolls to the needles, and presser members each opposing one of the grooves. The presser members are movable toward and away from the respective grooves independently of one another. By pressing selected one or ones of the presser members against the bottoms of the corresponding grooves with yarns sandwiched therebetween, the feed rates of the yarns can be freely changed independently of one another without unduly increasing the size of the yarn feeder or complicating its structure.

摘要： A pattern yarn feed device for use with a tufting machine in the manufacture of tufted articles includes at least one yarn feed roll assembly positioned on a frame of a tufting machine adjacent a yarn feed path. The yarn feed roll assembly has an elongate rotatable yarn feed roll having an exterior yarn driving periphery for engaging yarns thereon. A drive motor is provided for rotating the yarn feed roll. At least one yarn applying member, preferably a rotatable pinch roller, is provided as a part of the yarn feed roll assembly, and extends parallel to the yarn feed roll, and is orbitally moveable about the yarn feed roll. The at least one yarn applying member is selectively moveable from a first yarn receiving position spaced from the periphery of the yarn feed roll for receiving an intermediate portion of selected ones of the tufting yarns thereon, into a yarn applying position engaged with at least a portion of the yarn driving periphery of the yarn feed roll for applying the selected ones of the yarns thereto. In separate constructions, the pinch roller may be eccentrically orbited about the yarn feed roll from the yarn applying position into the yarn receiving position, or may be concentrically orbited about the yarn feed roll and then selectively moved into the yarn applying position at the completion of its orbital rotation about the yarn feed roll. In its yarn applying position, the pinch roller is normally resiliently urged into engagement with the periphery of the yarn feed roll.

摘要： An individually controlled needle tufting machine has a reciprocable latch bar for latching and unlatching selective needle holders, each needle holder being guided between a pair of guide plates and carrying a respective needle so that each needle selectively may be driven by the latch bar. The guide plates each include a plurality of curvilinear ridges and the edges of the needle holder are curvilinear and are received within a respective spaced apart pair of ridges within which they are guided as the needle holder reciprocates. The plates include vertically spaced apart inserts within which the ridges are formed. The needle holder has a yarn clamp mounted internally adjacent the bottom and a leaf spring has a leg mounted externally of the holder and has a leg entering internally to act upon and urge the yarn clamp.

摘要： A yarn feed mechanism for use with a tufting machine is disclosed. The tufting machine has a needle bar with an aligned series of spaced tufting needles disposed thereon, each of which is supplied with yarn from a yarn supply for penetrating a backing material to sew tufts of yarn therein. The yarn feed mechanism includes a support framework mounted on the tufting machine adjacent a yarn feed path extending from the yarn supply to the needles of the tufting machine, with at least one yarn feed roll assembly mounted for rotation on the support framework. The yarn feed roll assembly further includes an elongate yarn feed roll having an exterior yarn driving periphery extending along a longitudinal axis parallel to the needle bar of the tufting machine, the yarn feed roll being rotated in timed relationship with the reciprocation of the needle bar. An orbital yarn applying member spaced from the yarn feed roll is supported on the support framework and is movable about the yarn feed roll in an orbital path from a yarn receiving position to a yarn applying position. The yarn applying member is used to apply portions of selected yarns against at least a portion of the yarn driving periphery of the yarn feed roll in the yarn applying position for controlling the rate at which the yarn is fed to the needles of the tufting machine. The yarn applying member of the invention may comprise at least one concentrically orbited control rod spaced from and parallel to the yarn feed roll, or may comprise a pinch roller orbited eccentrically about the yarn feed roll, and constructed to be moved into a yarn applying position engaged with the periphery of the yarn feed roll.
