Abstract: A tufting machine is disclosed, including a drive system for driving reciprocation of one or more needle bars carrying a series of needles. A backing material will be fed through a tufting zone of the tufting machine, with the needles penetrating into and out of the backing material with the reciprocation of the needle bars by the drive system to form tufts of yarns in the backing material at increased production rates.

Abstract: 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 actuators 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 can be controlled in conjunction with the movement of the gauge parts, while the backing feed can also be controlled, to enable formation of tufts of yarns at an increased rate over the pattern stitch rate for the pattern of the tufted article being formed.

Abstract: A tufting machine has a main drive shaft, a looper shaft and parallel to the main shaft, a drive train therebetween in which a spindle supports, on its end, a sprocket which is driven by an endless belt from a wheel on the drive shaft. The other face of the sprocket carries a stroke control lug provided with a orbital crank pin which reciprocates a link connected to a lever on the looper shaft thereby for rocking the looper shaft, rocking the loopers carried by the looper shaft.

Abstract: Symmetrical, modular blocks each having a plurality of fixed, equally spaced, gauging elements, namely loopers, needles, and reeds protruding therefrom, the blocks are positioned on the sides of the guide bars of a tufting machine, each guide bar having transverse channels at equally spaced intervals. These channels respectively receive guide bars of the blocks when the blocks are removably positioned on the sides of the guide bar. Bolts or screws secure the blocks in place on their guide bars so that their needles, loopers, and reeds are appropriately gauged and positioned for tufting action, protruding toward the tufting zone.

Abstract: A tufting machine having individual crank assemblies for reciprocating the push rods which carry the needle bar. Successive crank shafts aligned with each other and parallel to two main drive shafts which are rotated in opposite directions. Gears on the main drive shafts respectively transfer power from the two drive shafts so as to rotate each successive crank shaft in a direction opposite from the direction of rotation of the preceding crank shaft. The connecting rods connected to the crank assemblies thus are thrown outwardly in opposite directions as the crank shafts are rotated, so as to balance the machine. Additional counter-balance weights are provided on the main drive shafts.

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.
