Definitions

  • the present invention relates, according to one its aspects, to a process for manufacturing a run-resisting fabric, and a knitted fabric structure obtained thereby, and in particular to a process for manufacturing a run-resisting, high-stability, reproducible, knitted fabric, with patterns variable within a wide range, and which is industrially stackable in packs.
  • the invention relates to a structure of knitted fabric manufactured by means of the process according to the invention.
  • the Italian patent No. 1,057,978 in the name of Toshikazu ITO discloses a knitted fabric comprising stitches connected in the direction of the warp and stitches connected in the direction of the weft, characterized in that a plain stitch of the knitting is formed using weft threads, in each longitudinal row of knitting a warp thread is knit-in into one of every two transverse rows in the form of a locking stitch, to form chain stitches, and sinker loops of said chain stitches are exposed for a long portion on the reverse side.
  • the aim of the abovementioned Italian patent was to provide a knitted fabric having an optional warp strip formed on its reverse, changing the warp color in the vertical rows, i.e. in the longitudinal rows of stitches.
  • Another object was to provide a tight-knitted fabric wherein the structure was not excessively elongated in the direction of the weft, preventing at the same time the forming of open gaps between the stitches, connecting all the chain stitches in the direction of the weft.
  • Another object of the abovementioned Italian patent was to provide a knitted fabric having a warp strip also on the front side by using a colored thread for stitches appearing on the front side every two transverse rows.
  • Said known fabric specifically provided for the manufacture of stockings, was satisfactorily stable, but it was substantially affected by two disadvantages: the first of said disadvantages resided in the poor flexibility in the execution of the patterns obtainable on said fabric, indeed due to the use of a colored thread for stitches appearing on the front face every two transverse rows.
  • the aim of the present invention is to provide a process for forming an run-resisting, reproducible fabric with high stability and with patterns which are variable within a wide range.
  • An object of the present invention is to provide a process of the indicated type which allows to manufacture a knitted fabric which can be stacked industrially in packs.
  • Another object of the present invention is to provide a process of the indicated type which allows to manufacture a knitted fabric having extremely fine mesh which is variable within an extremely wide range.
  • Still another object of the present invention is to provide a process for manufacturing a knitted fabric of the indicated type which permits extremely high productivity.
  • Yet another object of the present invention is to provide a process of the indicated type which allows to manufacture a knitted fabric which can have various patterns in various colors, and this without being limited to the production of stripes according to preset transverse rows of the knitting.
  • the above described aim and objects, and others which will become apparent hereinafter, are achieved by a process for manufacturing a run-resisting fabric as defined in claim 1.
  • the above described aims and objects, and others which will become apparent hereinafter, are achieved by a knitted fabric structure obtained by means of said process, as defined in claim 7.
  • said figures schematically illustrate a conventional plain-­knitted fabric, in particular a knitted fabric of the so-­called "chain” type, which is obtained on machines fed not by a single reel but by a series of parallel threads which are arranged so as to form as many longitudinal rows of loops: the linking, in particular, is executed both in the direction of the weft and in the direction of the warp or chain, so that each longitudinal row of loops is linked to the nearby longitudinal row.
  • the obtained knitting is of the run-resisting type, and is constituted by a transverse series of rows of knitting or transverse rows and by a longitudinal series of lines of stitches.
  • Said known plain knitting is very loose, and the only possible variation is a variation in colors or based on appropriate selections of appropriate types of needles, said selection being generally obtained by means of cams acting on said needles.
  • Said known knitting is furthermore not very stable and cannot be industrially packaged in packs, this defect adding to the abovementioned looseness of said knitting and to the poor versatility of patterns obtainable.
  • the process according to the invention which can be carried out on a rectilinear knitting machine of the type having means for the simultaneous feeding of at least two threads to the needle, and more specifically of a thread F, which can be generally likened to a weft thread, and a thread F1, which can be generally likened to a warp thread, said threads F and F1 possibly having preset different colors.
  • each individual needle 1, 2, 3, 4 is loaded, besides with the thread F carried by a thread-guiding element controlled by the carriage of the machine, also by a further thread F1 guided by a tube-like element which is part of a bar of tubes (not illustrated) which constitute a bed of tubes which forms, together with the needle bed, a configuration which is substantially in the shape of an inverted V and has been specifically described in the abovementioned type of rectilinear knitting machine.
  • a respective tube T for the feeding of individual warp threads has been associated with each needle 1, 2, 3, 4 in the machine according to the abovementioned type of rectlinear knitting machine.
  • the process according to the invention is as follows: in a first step, the carriage of the machine (not illustrated) selects, by virtue of its cam means and according to the program of the machine, preset needles of the plurality of needles which form the needle bed, the selected needles being caused to protrude from the vertex of the inverted-V configuration of the needle bed.
  • the selected needles are fed with the weft thread F by means of thread-guiding means, not illustrated specifically and controlled by the carriage (also not shown), and further warp threads F1 are simultaneously fed to the selected needles by means of said tubes T.
  • the needles, with the threads engaged thereon are dropped, e.g. during the return stroke of the carriage, to form a transverse row of knitting constituted by so-called "locked" stitches, i.e. stitches formed by means of the association of the thread F of the thread-guide and of the thread F1 of the corresponding tube.
  • each individual tube can be moved, after being raised, according to the configurations shown in figure 6, i.e. according to an open loop or according to a closed loop; said tubes, as mentioned, are all supported by a common bar which is not illustrated.
  • Figure 9 schematically illustrates the structure of knitted fabric manufactured with the previously described process according to the invention.
  • the knitting structure according to the invention is rather tightly knitted and has, in a vertical direction, for the specific illustrated execution, striped regions with locked stitches, e.g. variously colored ones, which besides imparting stability to the fabric, also impart pleasant color effects thereto.
  • Said run-resisting knitting structure is furthermore greatly versatile from the point of view of obtainable patterns and furthermore, by virtue of the fact that a respective tube is associated with each needle on two generally very wide needle beds which comprise a large number of tubes and needles, it is possible to obtain a very fine degree of mesh, variable in any case within an extremely wide interval.
