Definitions

  • the gauge parts are such that they always remain in registry during relative movement thereof.
  • the gauge parts may be shifted distances lesser than the actual gauge of the parts so that rows of tufts may be produced which are spaced more closely than the gauge of the parts themselves. It will be seen, therefore, from the following specification that relatively dense pile fabrics can be produced without requiring relatively fine gauge parts with their inherent problems of operation.
  • the present invention overcomes the inherent limitations in the above-described mechanisms and further provides a device wherein relatively dense pile fabrics can be produced without requiring the use of relatively fine gauge parts.
  • the needles, loopers, and knives are tied together for relative lateral shifting movement so that all gauge parts remain in registry during shifting relative to the backing fabric. Further, since the gauge parts are shifted relative to the needle plate and backing fabric while remaining in registry, it is possible to shift the gauge parts at spacings closer together than the distance between the gauge parts themselves so that relatively closely spaced rows of tufts can be produced.
  • FIG. 1 is a partial cross-sectional view of a tufting machine embodying the invention
  • FIG. 2 is a partial sectional view of the tufting machine shown in FIG. 1 and taken at right angles thereto;
  • FIG. 3 is an enlarged partial perspective view of the mechanism of the invention.
  • a tufting machine is illustrated therein as comprising a machine frame 10 including a main shaft 12 supported for rotation therein. Carried on the main shaft 12 are a plurality of eccentrics 14, only one being shown in FIGS. 1 and 2, each of which carries a connecting rod 16 which drives a push rod 18 suitably supported in the machine frame 10 for reciprocating motion therein. A plurality of needles 20 are carried for reciprocating motion with the push rods 18 and for penetrating a backing fabric F as the backing fabric F moves across a needle plate 22 which supports the same.
  • the backing fabric F is fed through the machine in a wellknown manner such as by feed rolls disposed fore and aft of the machine, as illustrated in FIG. 1, for example.
  • a plurality of loopers 24 Disposed below the backing fabric F and the needle plate 22 are a plurality of loopers 24 which are supported for oscillating movement in a looper shaft 26/Associated with each looper 24, there may be provided a knife 28 which is supported in a stationary manner in a knife block 30.
  • the loopers 24 seize and hold the loops of yarn inserted through the backing fabric by the needles 20 and as the backing fabric F is fed along the needle plate 22, the loops move toward the rear of the looper 24 where they may be cut by the knives 28.
  • the mechanism described thus far is considered conventional in the tufting art.
  • the needles 20 are carried by a needle bar 32 which is disposed for relative lateral shifting in a needle bar support mechanism 34 which is in turn suitably attached to the push rods 18.
  • the needle bar 32 is also attached at least at one end thereof to a support member 36 (FIGS. 2 and 3) and is supported in a U-shaped channel thereof so that the needle bar 32 may reciprocate relative to the support member 36.
  • the looper shaft 26 is also supported at one end thereof to the support member 36 and is carried thereby so that the looper shaft may be oscillated or rocked relative to the support member 36.
  • a sliding plate 38 Connected to the bottom of the vertical support member 36 is a sliding plate 38 which is disposed for relative sliding movement in a plate support member 40 which is fixed to the frame of the machine.
  • the knife shaft 30 is also fixed to the sliding plate 38 for sliding movement with said plate 38.
  • a rod 42 is fixed to an outer face of the support member 36 and is supported in a bearing in the machine frame 10 so that said rod 42 may be reciprocated relative to the machine frame.
  • the rod 42 is pivotably connected at its opposite end to a connecting rod 44 which is driven by an eccentric or cam 46. Motion is imparted to the cam 46 through a gear 48 carried by the main shaft 12, a chain 50, and a gear 52 which is part of a reduction unit or transmission drive 56.
  • the output of the transmission 56 is through a shaft 58 which in turn carries the cam 46.
  • the cam 46 is suitably designed to impart the degree of lateral shifting to the gauge parts in accordance with a desired pattern effect.
  • gauge parts is commonly used in the art to define the lateral distance between adjacent needles and associated loopers and which distance normally defines the distance between the rows of tufting in a normal tufting operation.
  • machine such as described in the aforementioned two patents, when relative shifting between the gauge parts and the backing fabric was brought about, it was necessary to shift at least a full gauge or from the distance between one needle to the other so as to maintain registry between the gauge parts and to insure no defects in the fabric. In the present invention, however, it is not necessary to shift a full gauge width since all the gauge parts shift simultaneously and registry is always maintained.
  • a further advantage of the invention lies in the fact that the design cam 46 need not be machined with as great a relative accuracy as required in the prior art machines, since there is no danger of the gauge parts operating out of register with one another.
  • a stationary frame including a head portion having a drive mechanism, a plurality of laterally spaced needles, a needle bar for supporting said needles, means supporting said needle bar for relative lateral shifting movement, means operably connecting said means supporting said needle bar to said drive mechanism for reciprocating said needle bar, said needle bar during reciprocating motion reciprocating said needles for inserting loops of yarn into a backing fabric, a plurality of laterally spaced loopers each being associated with a needle, a looper shaft supporting said loopers for intercepting the loops of yarn inserted by said needles and for holding the loops of yarn upon the return stroke of said needles during reciprocation thereof, means supporting said looper shaft for relative lateral shifting movement, laterally shiftable support means providing a common support for said needle bar and said looper shaft and coupling said needle bar with said looper shaft for simultaneous lateral shifting relative to said head, said drive mechanism and the backing fabric, and means for initiating lateral shifting movement of said laterally shiftable support means whereby said needles are
  • said means supporting said looper shaft includes means for supporting said loopers for oscillating motion.
  • said means for initiating lateral shifting movement of said laterally shiftable support means includes means for initiating lateral shifting movement of said support means relative to said backing fabric at least at distances less than the distance between adjacent needles.
  • said cutting means includes a knife block and a knife mechanism, and said knife mechanism being stationarily supported in said knife block.
