Definitions

  • a primary object of the present invention is to provide a broadly useful and relatively simple method of warpknitting seamless tubular fabric.
  • Another object is provision of various designs of seamless tnbular warp-knit fabric.
  • a further object is reduction in apparatus requirements for so knitting such fabric.
  • FIG. l is a double needlebed machine threading diagram utilizable according to the present invention.
  • FIG. 2 is a point pattern diagram for a point doane design of this invention
  • FIG. 3 is a point pattern diagram illustrating the interconnection of the front and rear panels of fabric in seamless manner according to the invention
  • FIG. 4 is a fragmentary plan of fabric formed according to this invention, showing especially the interconnected edge portions
  • FIG. 5 is a legend for FIG. 4;
  • FIG. 6 is a fragmentary plan of fabric formed according to this invention, showing especially a point portion of a point doane design and the immediately surrounding portion;
  • FIG. 7 is a fragmentary plan of another design embodiment of the invention.
  • the objects of the present invention are accomplished, in warp-knitting of seamless tubular net fabric on a double needlebed machine, by removing from each bed a needle at each end of each band -being knitted and utilizing, in interconnecting the fabric panels being knit on the respective needlebeds, each of two yarn guide bars threaded only at the opposite ends of each band and shogged similarly to the yarn guide bars forming the basic net.
  • no stitch is formed at the needleless positions, and the result is that the pattern being followed in the panels of fabric on the front and back beds is continued at the interconnection between the respective panels along their lateral edges, thereby producing seamrice less tubular fabric.
  • the respective con-A nector bars alternately form a plurality of stitches (usually three) on the actual end needle in the respective beds and then when shogged to the needleless position lay in on the opposite bed for a corresponding plurality of stitches.
  • the connector bars interchange function, upon being shogged to the needleless position, from duplicating the stitching action provided by the basic pattern guide bars to duplicating the laying-in action of the reinforcing guide bars. This action and the result thereof are sho-wn in the diagrams.
  • FIG. l is a threading diagram for a double needlebed machine according to this invention. It includes the threading for a particularly desirable point doane design as well as a basic seamless net construction. The diagram is broken away to avoid unnecessary repetition and to emphasize the unique nature thereof at the edge portions of the bands, parts of two bands being indicated. Usually a plurality of individual fabric items are formed alongside but separate I(or readily separable) from one another, the lateral extent of each being termed a band, and this invention is adapted to the formation of as many bands as desired commensurate with the size of machine being used, which may be expressed in number of needle positions (per bed). FIG. 1 shows fifty-six needle positions, plus two needleless positions, one at each end, per band.
  • the first two needleless positions at the right end of the machine are designated 00 and 0, and subsequent positions are numbered from 1 consecutively to the left, with the designations 00 and 0 added to the regular numbering of positions at which needles have been removed, thus: 57-00 and 58-0, the former being the last position in the rst band and the latter being the rst position in the second band.
  • a zero link positions a guide bar at the closest position to the pattern drum end of the machine (here assumed to be the right end) and that each increase by two in the link designation corresponds to a shoggng of each guide in the bar past a single needle position, as is conventional.
  • bars and are threaded at each needle position except the last, and as designated by ST form the basic net, on the front and back needlebeds, respectively.
  • Bars l and 1 0 are threaded at three consecutive positions of every four (i.e., three in, one out) and are designated LAY to indicate that the yarns guided thereby lay in a reinforcement to the basic net, on the front and back beds, respectively.
  • Bars g and 8, which are designated LO-P (for low-point), are threaded at half the positions at which bars I and IQ are not threaded, and bars and Q, designated HI-P (for high-point), are threaded at.
  • each of these four bars being threaded one in, seven out, with bars g and working the front bed and bars and Q the back bed.
  • the brackets at the extreme right of the diagram indicate that bars g and are nested; likewise, so are bars and Q.

  • FIG. 5 indicates the coding of the yarns in FIG. 4.
  • the solid black yarn is provided by guide bar 1 on the front bed and bar E on the back bed.
  • the cross-hatched yarn is provided by guide bar g on the front bed and bar Z on the back bed.
  • the unshaded yarn is provided by guide bar Q, and the stippled yarn by bar Q, on both beds.
  • the yarn from bar Q forms three stitches in the rear panel, like those formed by bar Z yarn therein, and the bar Q yarn is laid therein (corresponding to attempted stitches thereof at the left needleless position in the front bed) as the yarn is from bar throughout the panel. Meanwhile at the right seam the bar Q yarn stitches first as the bar Q yarn lays, and then lays as the bar Q yarn stitches.
  • the points of the exemplified fabric require two guide bars working on each needlebed. This is apparent from FIGS. 1 and 2, for example.
  • the terms high-point and low-point denote the respective resulting locations and structures in each panel of the fabric. At each point one of the hexagons is filled in by the yarn laid in from the particular bar. The resulting appearance thereof is shown in FIG. 6.
  • FIG. 7 shows an alternative laid-in pattern useful in conjunction with the same basic hexagonal net. Contrary to the point doane pattern, in which no difference in yarn denier was suggested, this modification employs an obviously much heavier yarn than used in the basic net. Also, the heavy laid-in yarn extends over more than two adjacent wales, thereby lending itself to production of a figured pattern as is itself conventional.
  • Raschel tubular fabric made up from two knitted panels joined seamlessly along their corresponding lateral edges and characterized thereat by continuation of a balanced basic net configuration formed throughout the panels by stitching yarns and laying-in yarns, each lateral edge junction comprising a pair of yarns knitted differently from the yarns forming the basic net within the panels, the respective yarns in each such pair being knitted identically with the corresponding individual yarns in the other lateral pair, the structure of the fabric along the lateral edges duplicating the net structure present within the panels except for interchange of the respective yarns in each pair between stitching and laying in along successive configurational openings whereas within the panels the stitching yarns stitch throughout and the laying-in yarns lay in throughout the structure.
  • Seamless tubular six-bar Raschel fabric according to claim 1 comprising a balanced net configuration characterized by hexagonal coniigurational openings.
  • Raschel fabric according to claim 2 wherein occasional configurational openings are opacied by yarns laid-in thereacross.
  • Raschel fabric according to claim 1 characterized by chain readings for guide bars for the basic net yarns as designated under columns l, 7 and Q below and by chain readings for guide bars for the interconnecting yarns as designated under columns Q and Q below, with 1 and E threaded three in, one out and with l starting ybetween the first and second needles in the band and with E starting between an initial needleless position and the first needle in the band, with and 1 threaded at all except the first and last positions in the band and both starting between the first and second needles, and with Q and Q threaded only at the first and last positions in the band and with Q starting between needleless positions at the beginning of the band and between the last two needles in the band and with Q starting between the initial needleless position and the first needle in the band and between the last needle and a final needleless position in the hand:
  • Raschel fabric according to claim 4 having a point doane design characterized by chain readings for guide bars for the design yarns as designated under columns 2 Q, and Q below, each threaded one in, seven out and with g and being threaded at half the positions at which l and I Q are not threaded, with g starting between the initial needleless position and the first needle in the band and with starting between the sixth and seventh needles in the band, with and Q threaded at the other half of the positions at which l and Q are not threaded and 8 with starting between the fourth and fifth needles and with Q starting between the second and third needles:
