Definitions

  • the present invention relates to knitting machines, and concerns especially such machines adapted for knitting a fabric having free loops, or a fabric provided with p1le which can be used for rugs or carpets, fur imitations, linings and for similar purposes.
  • the cutter is preferably of a .rotating type, such as a rotary knife.
  • a further object of the invention is to provide, in combination with a rotating cutter, means adapted to ensure that all of the loops will be securely and evenly cut.
  • the co-operating cutting means may consist simply of a groove located underneath the loop elongating needles.
  • the dial needles are the loop elongating needles and the cutter is in the form of a rotating knife the cutting edge of this knife would extend into the groove and one edge of the latter would then constitute one of two cutting edges between which the loops are cut.
  • Another way of performing the cutting is to arrange a stationary finger in front of the elongated loops and close to the rotating cutter, this finger being inclined and extending towards and underneath the loops so that with the finger secured in this position, the loops will slide along the finger and be pulled towards the cutting edge of the rotating knife and be cut between the finger and the said cutting edge.
  • the machine is built like a conventional circular knitting machine of the cylinder and dial type with the difference that the dial is located on the outside of the cylinder; that is to say, the dial in this case is in the form of a ring surrounding the cylinder.
  • FIGURE 1 diagrammatically depicts a few cylinder and dial needles of such a machine and a rotating cutter set out to illustrate the general method of knitting accord ing to the invention
  • FIGURE 2 is a diagrammatic vertical sectional view of a portion of the head of the machine taken on the line IIII in FIGURE 1,
  • FIGURE 7 is a detail plan view corresponding to FIG- URE 6.
  • FIGURE 8 is another vertical sectional view illustrating a modification of the cutting arrangement shown in FIGURES 6 and 7, and
  • FIGURE 9 is a detail plan view corresponding to FIG- URE 8.
  • the numeral 1 indicates the cylinder needles of a conventional circular knitting machine of cylinder and dial type and 2 are the so called dial or rib needles.
  • 3 (FIGURE 1) represents the customary feeding plate of such a knitting machine, this plate being furnished with yarn guide 4 through which a base yarn 5 is fed in beneath the dial needles 2.
  • a yarn guide 6 which is located above the dial needles, and is employed to feed in a pile yarn 7.
  • the cylinder needles 1 are furnished with butts 8 which are engaged in a cam track provided between cams fitted in the customary cylinder cam box and by means of which cams the cylinder needles are reciprocated, i.e. advanced upwardly and retracted downwardly.
  • the dial needles 2 are provided with butts 9 arranged to be acted upon by cams in a dial cam cap (not shown), these cams serving to advance and retract the dial needles radially.
  • each dial needle 2 is used to pull the pile yarn and thereby form an elongated loop 15 so that the relevant cylinder needle 2 will be in its retracted position when the said elongated loop is cut by the cutter edge 16. In this way the pile 13 will from the outset assume a more natural condition since the loops 15 are drawn out nearly perpendicularly from the base fabric 14.
  • a dial 17 is in the form of an external ring surrounding a cylinder 18 equipped internally with the cylinder needles 1.
  • the dial or rib needles 2 in this case thus work in opposite directions as compared with the dial needles shown in FIGURES 2 and 3.
  • the cutting knife in this modification is mounted directly on the dial cap and funcon the base fabric 21.
  • FIGURE 5 is shown an arrangement wherein the needle dial 17 is provided with a peripheral groove 22, and the cutting edge 16 of the cutter 10 extends into this groove for co-operation with the edge 23 thereof.
  • the co-operating edges 16 and 23 thus function after the manner of a pair of scissors to cut the elongated loops 24 and so form a pile on the base fabric 25.
  • FIGURE 6 Another way of cutting the elongated loops by a knife action to provide a finger (see FIGURE 6) 26 which is mounted on the cylinder cam box 27 containing the earns 28 for actuating the needles 1 in the cylinder 29.
  • This finger 26 extends close up to the cutter 10 and is inclined so that it will pass in between the elongated loops 30 and the dial 31 and function to pull these loops 30 outwardly against the cutting edge of the cutter 10. The finger 26 will thus co-operate with the cutter 10 in order to obtain a scissor-like effect or action.
  • FIGURE 7 is shown the manner in which the finger 26 extends from underneath the cutter 10 and in between the loops and the dial 31.
  • each of these loops is cut in two places, so that in respect of each loop there will be a small wastage 32 of yarn (FIGURE 5), and in order to avoid such waste, means may be provided to turn and spread the elongated loops suchwise as to form a shed.
  • the limbs of the elongated loops 37 will be engaged in the grooves 34 and 35, so as to open out these loops in a transverse direction with respect to the circle of cylinder needles, thus enabling a finger 38 underneath the dial to be inserted into the opened out loops.
  • This finger 38 may be of the same form as the finger 26 and may also co-operate in the same way with a cutting knife 10, such as shown in FIGURES 5 and 6.
  • the finger 38 may be provided with a groove 39, wherein the cutting edge 40 of a rotating knife 41 is located. In this way the same cutting effect as shown in FIGURE 6 is obtained with the difierence that any waste of yarn is obviated.
  • the above described elements may be used not only in combination with a knitting machine of the circular cylinder and dial type, but can also be readily applied to other types of knitting machines, such for instance, as Interlock machines and machines equipped with Jacquard designing mechanism.
  • the method of forming cut pile including the step of, while the loops are retained in the drawn condition by the dial elements, severing the bight ends of the drawn loops against the dial to sever the loops to form the cut pile.
  • a knitting machine comprising two beds at an angle to each other and spaced slightly from each other and each having a needle mounting surface, two sets of needles, a set reciprocally mounted in a surface on each of said beds for reciprocation toward a line formed by the intersection of the surfaces in which said sets of needles are mounted, the needles in one of said sets being adapted to knit a base yarn and a pile yarn to form a base fabric and the other of said sets of needles cooperating with said first set of needles to form pile loops of said pile yarn, and a cutter mounted adjacent said line and having a cutting edge projecting toward one of said beds from the side of the surface of said other bed in which the needles are mounted which is remote from said one bed, said cutter being adapted to cut the pile loops of said pile yarn adjacent said other set of needles.
  • said cutter comprises, in combination, a rotating knife and a guide finger adjacent the edge of the knife and extending into the space between said beds from the side of the surface in which said one set of needles lies opposite the other set of needles for engaging loops of said pile yarn and guiding them against said rotating knife.
  • a knitting machine comprising two beds at an angle to each other and spaced slightly from each other and each having a needle mounting surface, two sets of needles, a set reciprocally mounted in a surface on each of said beds for reciprocation toward a line formed by the intersection of the surfaces in which said sets of needles are mounted, the needles in one of said sets being adapted to knit a base yarn and a pile yarn to form a base fabric and the other of said sets of needles cooperating with said first set of needles to form pile loops of said pile yarn, and a cutter mounted adjacent said line and having a cutting edge projecting toward the bed having the other of said sets of needles, said cutter being adapted to cut the pile loops of said pile yarn adjacent said other set of needles, the said bed having a groove therein into which said cutting edge projects.
