Abstract: 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.

Abstract: A tufting machine with an improved pattern yarn feed and distribution device for use in tufting a graphic pattern into the face of a tufted article. An improved pattern yarn feed drive is provided with at least two separate yarn drive control sections which together provide an increased number of controls such that any one control is adapted to drive a predetermined number of tufting yarns selectively passed thereabout for minimizing the length between any one of the tufting yarns and its respective tufting needle. An improved tube bank configuration is used with the pattern yarn drive assembly, and comprises at least two tube bank sections, each of which is also constructed and arranged to minimize the length of the yarns passed therethrough from a respective one of the yarn drive controls to a respective one of the tufting needles.

Abstract: 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.

Abstract: Front and rear needle bars are provided with front and rear needles for inserting yarns into a backing material. An excess of front loopers are provided for the front needles and an excess of rear loopers are provided for the rear needles. The front loopers respectively face the rear loopers and are respectively aligned with each other. The needle bars are shifted laterally so as to provide longitudinal rows of tufts formed by the front needles providing spacing between the tufts of a longitudinal row which space is filled in by the tufts of rear needles.

Abstract: A yarn feed mechanism for a tufting machine includes yarn feed rolls disposed along parallel axes transversely adjacent to the parallel paths of travel of yarns from yarn sources to the needles. A yarn control assembly surrounds each roll, each yarn control assembly having a pair of opposed, concentrically mounted, indexing plates at opposite ends of each roll. Each pair of indexing plates carries a plurality of individually removable cimcumferentially spaced, yarn control rods, the plates being manually rotatable about the axis of the roll, independently of the rotation of the roll. By collecting intermediate increments of selected yarns on one of the rods, then rotating the indexing plates, with the rod installed to selected positions, the rod is moved in an orbital path for applying the yarn increments to portions of the periphery of the roll, such that the roll feeds controlled successive amounts of applied yarns toward the needles.

Abstract: A tufting machine with front and back laterally shiftable needle bars carry needles for producing loops in a backing material the accent yarns being fed to the needles by yarn feed controls and the border yarns by standard feed. The operation of the yarn feed controls is electrically operated by a computer which operates according to a pattern in memory, the lateral shifting of the needle bars being synchronized with the operations of the yarn feed controls. By producing high and low loops with the accent yarns, the low loops are hidden by the overlay of level tufts so that spaced, isolated pin dots are visible. The memory for the pattern is on a floppy disc created using a mouse and a second computer which displays both the amount of lateral shift for both needle bars and the high and low loops of the accent yarns. A print out of the displays are used for both threadup and the production of cams for controlling lateral shifting.

Abstract: A tufting machine is provided with separate motors which drive the main drive shaft, control the feed of the backing material and control the bedrail height. A computer is electrically connected to these motors and to the yarn feed controls. The software indicates patterns to be produced, informing the computer to control the number of stitches per inch of backing, the weight of face yarn per square yard, the pile height, the amount of yarn fed to the needles and the linear length of carpeting produced. The computer also dictates the schedule by which prescribed lengths of additional patterns are produced by the tufting machine and can control a number of such tufting machines. When the pile height is to be changed, the computer automatically controls the main motors for rocking the main shaft, to reciprocate the needles while controlling the yarn feed controls and the motor to the bedrail.

Abstract: Laterally shiftable front and back needle bars are slideably mounted on a main needle bar, the front needle bar carries a front row of needles and a back needle bar carries a back row of needles. Cut pile loopers cooperate with the needles of the back row and cut-loop loopers cooperate with the needles of the front row. Needles in the front row are larger and handle larger size yarns than needles in the back row and a yarn feed control dictates whether yarns in the front needles make low loops or high cut piles.

Abstract: A conventional tufting machine is provided with front and back juxtaposed, laterally shiftable, needle bars positioned on a common needle bar support, the needles of the front needle bar cooperating with loop pile loopers and the needles of the back needle bar cooperating with cut-loop loopers. Yarn feed controls respectively feed yarns to the needles according to individual prescribed patterns. The needle bars are respectively shifted laterally according to individual prescribed patterns.Tufted fabric produced by the machine is illustrated in which the loop tufts produced by the front needles are of relatively small cross section while the selectively cut or loop tufts produced by the back needles are of relatively large cross section. The large loop tufts are interspersed with small loop tufts due in part to lateral shifting of the needles.
