摘要： A knife assembly for a fine gauge tufting machine comprises a rectangular clamping bar and a series of knife blocks mounted side by side on the knife bar. Each knife block carries a number of knives mounted in parallel grooves in the knife block machined in a direction to present the knives to loopers of the machine at the desired cutting angle. The knives are retained in each knife block by a plate and clamping screws which extend through the plate to engage the edges of the knives. Each knife block has a rearwardly extending peg which is clamped in a hole in the knife bar with the knife block orientated to present the knives to the loopers at the desired pressing angle.

摘要： A knife block for use in a fine gauge tufting machine carries four knives, disposed in pairs on opposite sides of a central web with their edges engaged in opposed pairs of grooves in the block. The knives are retained in the block by two knurled cylindrical clamping blocks, which are disposed in slots in the block and are pressed by clamping screws into engagement with the edges of the knives.

摘要： The combination, with a source of supply of a warp of yarns and a mechanism for operating on the yarns, of a yarn compensator which stores yarn and is disposed between the source and the operating mechanism, the compensator including feed rollers operative to draw the yarns from the source at a greater rate than it can be accepted by the operating mechanism and means for driving the feed rollers, and a detector for detecting faults in the ends of yarn in the source, said detector being operative on detection of a fault to stop the feed rollers and to cause the operating mechanism to run at a lower speed.

摘要： A needle bar for a tufting machine, comprising a main bar having a row of holes uniformly spaced at a coarse pitch, a multiplicity of contiguous segments fitted into a longitudinal location groove in one face of the main bar, each segment having a peg accommodated in one of said holes in the main bar and retained therein by a locking screw and a row of finer holes, disposed parallel to the holes in the main bar and uniformly spaced at a finer pitch than the holes in the main bar, and needles mounted in groups in the holes in the segments to extend away from the main bar and retained in said holes by locking screws, the number of needles in each group being equal.The conventional needle bar for a tufting machine consists of a massive bar, of rectangular cross section, conveniently 1" square, which is reciprocated vertically by push rods and is formed, at uniform pitch, with vertical throughgoing holes into which the shanks of the needles are fitted and secured in position by screws fitted into horizontally extending throughgoing holes in the bar.Difficulty arises, however, in the manufacture of the needle bar when the gauge of the machine, i.e. the spacing between adjacent needles, is required to be very fine, e.g. 1/16" or 1/10". Thus in a typical case, a needle bar 1721/2" long may require to be drilled with no less than 1662 holes, each having a diameter of 0.08", disposed at a pitch of 0.10". Since the required drill is extremely fine, it is extremely difficult to drill these holes accurately and in the event of error the entire needle bar must be scrapped.It is possible to mitigate this difficulty by the use of a staggered needle bar, having two rows of needles with the needles in one row pitched midway between those in the other row. This expedient is not, however, available in the case of fine gauge machines for making cut pile fabric because there is insufficient clearance between the needles in the two rows for the passage of the loopers, which catch the loops of yarn projected through the backing fabric by the needles.The invention provides a needle bar for a tufting machine, comprising a main bar having a row of holes uniformly spaced at a coarse pitch, a multiplicity of contiguous segments fitted into a longitudinal location groove in one face of the main bar, each segment having a peg accommodated in one of said holes in the main bar and retained therein by a locking screw and a row of finer holes, disposed parallel to the holes in the main bar and uniformly spaced at a finer pitch than the holes in the main bar, and needles mounted in groups in the holes in the segments to extend away from the main bar and retained in said holes by locking screws, the number of needles in each group being equal.

摘要： Stop spots in pile fabrics are avoided in the manufacture of loop and cut pile fabrics by continuously reducing the operating speed of the needle drive shaft before the machine is stopped, when such stoppage becomes necessary in the course of the fabric manufacture, and again continuously increasing the shaft operating speed to its normal value after start-up.
