Definitions

  • a dense 112/266 fabric is produced having rows of pile tufts which are spaced [5 l l Cl. less the distance of he spacing between adjacent needles Fleld 0f v as viewed in the direction of the backing fabric feed.
  • the guage of the machine is measured by the transverse spacing between adjacent needles.
  • the longitudinal [56] References Cited rows of tufting produced through the apparatus of the present UNITED STATES PATENTS disclosure are spaced less than the guage distance.
  • WITNESS ATTORNEY DENSE PILE TUFIING MACHINES BRIEF DESCRIPTION OF THE INVENTION prises in general a sliding'needle plate mechanism which shifts the needle plate and the fabric relative to the needle bank and in the transverse direction so as to eliminate the straight-line appearance of the tufting on the pile side of the fabric.
  • the machine illustrated therein is mainly directed to the production of fabric of'the so-called loop pile variety.
  • aplurality of loopers are provided below the backing fabric and are disposed so that they face in a direction opposite to the direction of fabric feed.'As loops are produced through penetration of the needles and are picked upby the looper mechanism, the loops are fed toward the rear portion of the looper by the advancement of the backing fabric. While the loops are on the loopers, they permit some lateral shifting of the backing fabric: but restrain the backing fabric from shifting a full guage width or the distance between one needle to the next.
  • the'apparatus is' designed so that the needles penetrate the backing fabric during a portion of the lateral shifting thereof so as to restrain the lateral shifting of the backing fabric after a predetermined amount of shifting has occurred while the shifting mechanism continues to shift relative to the backing fabric.
  • the backing fabric is shifted substantially only one-half the distance between adjacent needles to produce parallel rows of tufting which are relatively closely spaced and are substam tially one-half the guage of the guage parts of the machine.
  • FIG. 1 is a fragmentary sectional view of a tufting machine embodying the present invention
  • FIG. 2 is a fragmentary perspective view of the pile forming elements of the machine illustrated in FIG. l,'portions of the machine having been eliminated for purposes of illustration;
  • FIG. 3 is a fragmentary top plane view of the needle plate of the machine of FIG. 1 with broken-away portions of a tufted fabric in position thereon and portions of the machine again having been eliminated for purposes of illustration.
  • the frame 10 of a generally conventional cut pile tufting machine such as disclosed, for example, in U.S. Pat. No. 3,084,645, issued to R. T. Card.
  • the frame I0 includes a head 12 in which is journaled a driven main shaft 14.
  • a plurality of eccentrics I6, only one of which is shown, are supported on the main shaft 14, each of which eccentrics is connected by a link or connecting rod 18 to a pushrod 20 mounted'substantially vertically for endwise'sliding-in the lower portion of the head 12.
  • the lower ends of the pushrod 20' are connected to a needle bar 22 which carries a plurality of transversely spaced, yam-carrying needles 24 that are substantially aligned laterally of the machine, as viewed in the drawing.
  • a needle bar 22 which carries a plurality of transversely spaced, yam-carrying needles 24 that are substantially aligned laterally of the machine, as viewed in the drawing.
  • a machine bed 26 is provided on the lower portion of the machine frame 10 and supports a needle plate 28 thereon;
  • the needle plate 28 includes a plurality of spaced grooves in the top surface thereof and in each of which there is supported a needle plate finger 30, which needle plate finger 30 need only'be of sufficient length to support the backing fabric F as the needles penetrate said backing fabric to project loops therethrough.
  • an oscillatorylooper or hook shaft 32 Suitably supported in the machine frame 10 and beneath the needle plate 28, there is provided an oscillatorylooper or hook shaft 32 which carries a plurality of spaced loopers 34, each of which is adapted to cooperate individually with one of the needles 24 to seize a loop of yarn presented by the needle and to hold the same as the needle is withdrawn from the backing fabric;
  • the loopers 34 are supported in the looper shaft 32' so that they are facing a direction opposite to the direction of fabric feed as indicated by the letter A. It will be apparent that as the backing fabric is fed and loops are formed, they will be seized by the loopers 34 and fed toward the rear portion thereof.
  • each looper 34 there is provided a knife 36 which is supported in a knife shaft 38 for cutting the loops as they are fed toward the most rearward portion of the looper.
  • the knives are'stationary but may be rocked relative to the loopers.
  • a presser foot 39 is also provided over and in spaced relation to the fabric F and is carried by the head in the usual manner (by means not shown). The presser foot 39 is adjusted just to clear the backing and acts to prevent the backing from following the needles as the needles are withdrawn.
  • the backing fabric F is fed longitudinally across the needle plate 28 in the direction of arrow A by conventionalfeed means such as that disclosed in U.S. Pat. No. 2,840,019 to M. M. Beasley.
  • This means comprises in general a fabric feed element and a guide means, both of which are in the form of driven fabric feed rolls and include a feed roll on the fore end and a feel roll on 'theaft end of the machine arranged, respectively, in back and in front of the line along which the needles 24 penetrate the backing fabric.
  • the feed rolls are preferably spiked to prevent slippage of the fabric relative thereto, both laterally and tangentially.
  • lt is also preferable to operate the aft feed roll at a slightly greater speed than the fore feed roll so that the fabric is held taut, for reasons as best explained in the aforementioned patent.
  • the needle plate 28 is mounted on the bed 26 for sliding movement laterally of the machine, that is, in a direction parallel to the line of needles.
  • the needle plate 28 is guided by a guide bar 40 secured to the bed 26 and butted against the edge of the needle plate opposite to the edge from which the fingers 30 extend. Shoulder screws 42 extend downwardly into the bed 26 through stepped slots 44 in the needle plate 28 to permit relative sliding movement of the needle plate 28 with respect to the bed 26.
  • an upstanding lug 46 to which there is pivotally connected a link or rod 48 at one end thereof, and the opposite end of the rod 48 is pivotally connected to the lower end of a cam follower lever 50 which in turn is pivotally supported intermediate its ends at pivot point 52.
  • a cam follower S4 is provided on the upper end of the lever 50 which cam follower rides in a cam track 56 provided in a cam 58.
  • the cam 58 is mounted on a shaft 60 joumaled in bracket 63 on the machine head 12 which shaft is rotated by a worm gear 64 mounted on a countershaft 66 which in turn is driven by a chain 68 entrained about a sprocket 70 carried by countershaft 66 and a sprocket 72 carried by main shaft 14.
  • the cam is driven in synchronous movement with the main shaft of the machine which in turn also drives the tufting components.
  • the cam is designed to initiate pivotal movement of the lever 50 during the downstroke of the needles 24, so that sliding movement of the needle plate is initiated while the needles are traveling toward the backing fabric F for penetrating said backing fabric with a loop of yarn.
  • the cam track 56 is also designed to initiate sliding movement of the needle plate 28 at least a full guage distance or at least the distance from one needle to the next adjacent needle. Thus, if the guage or distance between the needles is five thirty-seconds of an inch, one full sliding step of the needle plate 28 would be five thirty-seconds of an inch.
  • the operation of the apparatus of the invention is generally as follows.
  • sliding movement of the needle plate 28 is initiated a full guage distance by the cam mechanism.
  • the cam mechanism As the needles descend, they will intercept the backing fabric F as it is moving laterally with the needle plate 28 and will penetrate the same with each needle passing between a pair of needle plate fingers 30.
  • the full step sliding movement of the needle plate 28 will not be completed at this time but will continue the remainder of its sliding action. Due to the fact that the needles have intercepted the backing fabric prior to the full stepping movement of the needle plate, the backing fabric will be restrained from moving the full guage distance along with said needle plate.
  • loops will be fed onto the loopers and will be held thereby until they are fed to the rearward portion of the looper for cutting by the knives 36.
  • loops are held by the loopers 34 until the loop farthest back on the looper reaches the knife wherein it will be cut and the next loop will not be cut until it is fed back on the looper by movement of the backing fabric F.
  • the holding of the loops on the loopers 34 also serves to restrain the backing fabric from moving a full guage distance with the needle plate 28.
  • FIGS. 2 and 3 it can be seen that longitudinally extending parallel rows of tufts will be produced, which parallel rows are spaced substantially one-half the distance between adjacent needles.
  • FIG. 3 it will be seen that two parallel rows of tufts are produced at the needle penetration points between adjacent needle plate fingers 30 with the two parallel rows having a common zigzag backstitch.
  • the fabric produced through the novel apparatus and method, described above will have spaced rows of tufts which are spaced at a distance substantially one-half the distance of the guage parts. In other words, if the guage of the needles and other tufting components if five thirty-seconds of an inch, the fabric produced thereby will have a guage of five thirty-seconds of an inch.
  • a one-fifth of an inch guage machine will produce one-tenth of an inch guage fabric. It will be apparent that this is very desirable since very fine or dense guage products can be produced using relatively wide guage parts, so that it is possible to use approximately one-half the guage parts that would normally be required for production of the guage fabric produced by the apparatus of the present invention. This also eliminates the need for using relatively fine guage parts with the inherent disadvantages thereof, such as difi'rculty in threading, maintenance, repair, replacement, etc. In addition to the elimination of the so-called comcob effect, which is an advantage in all machines of this type, various pattern effects can be produced by using a different color or textured yarns in different needles. It is also contemplated that the machine of the present invention can be used with needle banks having needles in a staggered relationship in comparison to the inline needle bank illustrated in the drawings.
