Definitions

  • the present invention relates to a method allowing the automatic production on a knitting machine, in particular single-cylinder, of a sock of the type with two concentric layers and threaded one inside the other.
  • socks consisting of two substantially concentric tubular structures and consisting of an inner layer and an outer layer, the two layers joining and being secured at the tip of the toe.
  • Socks of this type have advantages in terms of user comfort.
  • the two-layer socks of the type here concerned allow absorption and evacuation of naturally exuded moisture; but moreover the making of socks on two layers, makes it possible to put in place comfort structures in particular in the form of loops thus allowing the foot to rest on a real carpet inside the shoe ensuring a damping sensation at each contact of the foot on the ground and consequently in addition to a pleasure and a feeling of "hushed walking", the removal of a source of fatigue and discomfort.
  • the socks of the double type here concerned are traditionally made on a double cylinder knitting machine, the sock being knitted successively in one piece from the tip (open) of a layer, to the ribbing, knitting continuing without interruption through the ribbing of the other layer to the open tip of the second layer, after which the knitting operation is finished.
  • a structure is thus obtained in reality consisting of two socks symmetrically opposed by their common rib edges.
  • This operation has serious drawbacks in that it requires for each sock a manual operation intended to pass from a single collinear tubular structure, to a tubular structure with two concentric layers.
  • finishing operation represented by the joining of the two points, with the necessary assembly of four layers also represents an operation not without difficulties and which results in a terminal area of extra thickness at the level of the toe, source of inconvenience and inconvenience to the user.
  • the present invention relates to improvements which make it possible to produce, in a particularly simple and elegant manner, a tubular structure intended to conform a two-layer sock, and in which the structure with two concentric layers is obtained directly on the machine which secures the two layers when the knitting operation of the entire structure is completed.
  • the invention thus makes it possible to save the operation of shaping the sock by integrating the two layers into one another and it also considerably facilitates the finishing operation consisting in closing the the sock at the tip.
  • Patent US Pat. No. 4,467,626 discloses a method of knitting a sock in which, during part of the knitting, the circular knitting machine produces an inner layer concentric with the outer layer previously knitted to produce a two-layer sock on one part. of the foot and a layer on the ribs.
  • a first layer or inner layer is formed forming a uniform cylindrical tubular structure from the initial tip (waiting on the plate) to the rib edges, while the second outer layer or layer comprises at the appropriate level and in a manner known in itself, shaping the heel.
  • two flexible locating means are inserted at two diametrically opposite points on the needle cylinder, such as sections of filler threads, the two sections being diametrically opposite on the needle cylinder, and on the last rows of the single terminal layer (resulting from the junction of the inner and outer layers), the marks formed by the filler wires making it possible, during the finishing operation, to place the sock in order to close the toe, by automatically presenting the single terminal layer, face against face, along an appropriate and determined axis: and the two marks are positioned along a diametral axis perpendicular to the plane of symmetry of the heel conformation on the outer layer, so that the alignment of the single terminal layer between the two reference points, the single terminal layer being brought face to face, automatically produces a transverse line corresponding substantially to the alignment of the toes.
  • Figure 1 shows a view with partial cutaway of the sock finished and produced according to the method of the invention.
  • Figure 2 shows a schematic view showing the establishment of the first rows of meshes on the central transfer plate.
  • Figures 3 and 4 show subsequent phases of the sock during knitting in two successive phases of its production.
  • Figure 5 shows the final phase of production of the sock in which the two layers are joined by transferring the row of stitches on hold from the transfer plate to the set of circular needles.
  • Figure 6a shows the blank of the sock as it is delivered by the machine at the end of knitting in a cross-sectional view, with tubular inner sock, which in Figure 6b has a shaped heel.
  • Figure 7 shows a view with torn off the foot of the sock before the finishing operation, that is to say of joining the two faces of the tip.
  • Figure 8 shows the foot of the sock once completed and after the joining operation of the two faces of the tip.
  • Figure 9 shows a diagram of the successive work of the needles throughout the making of the tubular structure to conform the blank of the sock.
  • this plate is here represented diagrammatically and it is separated from the crown of the needles 1 by a distance in the form of a crown considerably enlarged for the simple clarity of the drawings, it being understood that in reality the transfer plate 5 comes into position immediately juxtaposed relative to the crown of the needles 1, thus allowing interference games between the transfer needles (not shown) positioned radially on the plate and the knitting needles 2,3,4 belonging to the crown 1.
  • the tubular structure is suspended; and as the two ends respectively on standby 7 and during knitting 8 are substantially at the same level, the knitting rows accumulating, the tubular structure thus shaped is at all times in a concentric position and consequently defining two layers, namely an inner layer 9 and an outer layer 10, joined by the lower corner gear 11.
  • the machine knits a uniform tubular structure and of constant section 12, which will constitute the inner sock; arrived at a suitable place corresponding to the level of the heel 14, the knitting machine makes in a known manner a protuberance (in Y) which will conform the heel on the outer sock 13.
  • This single terminal layer 15 extends over a few rows so as to subsequently allow the point to be secured and closed.
  • two sections of filler threads 16.16 ′ are brought automatically, when knitting the last row of the single end layer 15.
  • These threads are preferably of a coloring allowing them to be easily identified by eye and they effectively constitute each a mark which will allow the alignment and the correct positioning of the single end layer 15 during the final shaping operation for closure. of the tip.
  • These two locating wires 16 and 16 ′ are easily positioned on the machine, when knitting the end rows of the single layer 15, the filler wires 16 and 16 ′ being positioned diametrically opposite and perpendicular to the plane of symmetry of heel making.
  • Figure 1 on the one hand and the knitting diagram 9 on the other hand gives a detail of implementation and embodiment of the invention according to a particular form presented by way of illustrative example.
  • the inner layer 17a represents the inner layer in rib 1 x 1 identical to the outer layer 17b; one could however foresee that the inner layer 17a is produced on a jersey base like the whole of the inner sock of tubular structure with constant section (see FIG. 6).
  • the inner layer 18a is made in a jersey texture on cotton yarn vanized one row in two with lycra gum thread; we could alternatively make the stocking stitch in a vanized texture on all the rows.
  • the heel 20 has here been shaped in Y shape to ensure better comfort always in a looped texture called sandwich in cotton, polyamide or lycra, but the heel could be made in simplified form or in pocket form.
  • the foot 21 is knitted in the same texture as looped sandwiches in cotton wadding, polyamide or lycra; the foot can be knitted in full loops; it could also include loops on the sole sole, the upper being made in jersey.
  • the tip 22 can be shaped, diminished or straight, always in cotton, polyamide or lycra with loops up to the tip end.
  • the assembly of the two layers is obtained as previously described by transfer of stitches directly on the knitting machine; the 16,16 ′ embroidery threads ensuring good centering for remeshing.
  • the invention also makes it possible to produce socks with high decorative power; indeed the effect yarns or decorative yarns added during knitting, in the case of a conventional simple sock overflow and float on the inner face of the sock where they constitute a risk of snagging for example for the toes when the sock is put on, in addition to the unsightly appearance of these floating threads.
  • the effect yarns added during knitting on the outer layer can be left projecting on the rear face since this face is doubled by the layer constituting the inner sock; the decorative threads therefore remain hidden in the interface between the two layers while respecting the beautiful presentation of the assembly and the plain wall encountered by the foot when the sock is put on.
  • FIG. 6b shows these floating wires 23 between two rows 24, 24 ′ forming decorative stripes; the floating threads are trapped between the layers 13 and 12 and cannot attack the foot when the sock is put on any more than they are visible on the sock even turned over.
  • the invention also makes it possible to produce orthopedic socks comprising an inner layer forming a support or compression envelope associated with an outer layer of normal appearance decorated or not, thereby avoiding the sometimes unsightly appearance of care or medical socks.
  • the sock or inner layer can indeed be knitted with suitable characteristics to ensure the desired holding effect.
