  • the weft knitted fabric according to FIG.6 differs from the fabrics previously described and shown, on the one hand, by having cross stripes 7 of the double fabric alternating with cross stripes 8 of the single fabric and, on the other hand, by the construction of the connecting courses 5. While in the previous fabrics both single fabrics are interlocked and connected over the whole length of the linking courses 5, in the fabric shown in FIG.6 the connecting elements 9 are spaced apart according to a pattern scheme in the connecting courses 5, between which elements the single fabrics are not interconnected so that a hollow space is formed between them at such locations.
  • connecting element is to be understood to include that part of the connecting course 5 in which at one side of the double fabric there is at least adjacent one rib stitch 2a of one of the single fabric a pearl stitch 3a of the other single fabric, and at the other side there is behind each of the said stitches 2a, 3a a sinker loop 4a of the other single fabric.
  • the first, fourth, and fifth stitch courses from below are the linking courses 5 of the double fabric of FIG.6.
  • the connecting elements 9 are on the selvedges of the same, in the middle of the fourth and in the fifth course the connecting elements 9 are side-by-side over the whole length of the stitch course 5, analogously to the fabric shown in FIG.1.
  • the second and the third courses form the stripe 8 of the double jersey fabric.
  • the scope of the present invention is not limited to the illustrated examples of the fabrics.
  • the double fabrics of the different described embodiments can be combined in the fabric according to the invention in lengthwise and crosswise stripes with different known structures and pattersn, and the fabric can be of a color or relief pattern; the stretchability of extensibility of the same can be further reduced by a laid-in weft.
  • FIGS. 7, 8, and 9 are top views of the individual steps of forming the connecting course 5;
  • FIG.10 is a view from the symmetry plane of the two needle beds.
  • the course of the other single fabric is formed imme diately on the even-numbered needles 10 of the front needle bed 12.
  • the odd-numbered needles 10 are inactive and remain in the clearing position so that the sinker loops 4 of the stitches 2 of the second fabric are placed on the transferred stitches 3 of the first fabric.
  • FIG.9 The knitting of the next course of the first single fabric is illustrated in FIG.9, in which, for the sake of clarity, neither the previous course of this fabric nor the sinker loops 4 of the stitches 2 of the other fabric are illustrated.
  • the stitches 2 of the second fabric remain on the needles of the front needle bed 12 and the course of the first fabric is formed without stitch transfer.
  • the sinker loops 4 of the first fabric are, in the double fabric, also placed behind the stitches 2 of the other fabric, as shown in FIG.10; this figure illustrates the relative position of the stitches 2 and the corresponding sinker loops 4 after being arranged in the plane of symmetry of the two needle beds 11, 12.

  • the stitches 2 and 3, respectively, of the other fabric are not transferred on to the first needle bed 11 or 12, respectively, but remain on the needles 10 of the second needle bed 12 or 11, respectively.
  • the method of producing the fabric according to FIG.3 is similar to that used for the production of the fabric according to FlG.1, as far as the laying of the sinker loops 4 is concerned. All the sinker loops 4 are, namely, on the back of the double fabric. There is, however, a difference consisting in knitting each single fabric alternately on the front needle bed 12 and on the rear needle bed 11. Thus in each individual stitch course the method is exactly the same, when forming a fabric according to FIG.1, since in each individual stitch course while knitting one single fabric on the needle 10 of the front needle bed 12, the other fabric is knitted on the needles 10 of the rear needle bed.
  • the method of forming the linking courses of the fabric according to FIGA is similar to that of the fabric according to PIC-.1.
  • the other, not linking, courses 6 are formed according to a known method used when knitting a tubular fabric on a flat-bed knitting machine, i.e., the course of one single fabric is knitted on the front needle bed 12 and the second on the rear needle bed 11 without stitch transfer.
