Definitions

  • the present invention relates to a method and a device for effecting the union of two edges of a knitted tubular manufactured product, such as for example the remeshing of the tips of the stockings, at the end of the knitting of the manufactured product.
  • each stocking must be turned over so that the seam to be performed on the toes is on the underside of the stocking. After which the point comes closed by removing the said edge to be thrown and sewing together the stitches of the last half-row from the top of the foot with those of the last half-row of the plant.
  • the Italian patent application Nr. FI920194 describes a method for effecting the union of the two front edges of a knitted tubular manufactured product, especially a stocking and comprising the phase of manufacturing a knitted tubular manufactured product, with a circular machine with a cylinder , starting at the edge or cuff and ending at tiptoe which remains open, the process of which also comprises the following operational phases: - lifting a predetermined number of needles from a first half-row with the respective adjacent meshes up to a predetermined level: by half-row being understood a plurality of adjacent meshes and which belong to an edge of the tip of the manufactured product; - raise a predetermined number of needles in a second half-row with the respective stitches, and bring them to the same level as those in the first half-row; - take the stitches from the first half-row, lower the corresponding needles and transfer them with a 180 ° turn around a diametrical horizontal axis of the needle cylinder, so that each stitch thus inverted engages the needle
  • a device for implementing said method which comprises: - cam means for the vertical movement of a number of predetermined needles of a first and of a second half-row of stitches of the tip of the manufactured product in production, which means are in the active condition when the knitting cams of the circular machine are in the inactive condition and vice versa; - Means for removing the stitches from said first half-row and turning them 180 ° around a horizontal diametral axis of the needle cylinder, with a pair of staples for each stitch and at least one corresponding latch, opening and closing respectively, each of which is slidably housed in a corresponding recess in a semi-circular sector: said sector being mounted rotating with angular amplitude of 180 ° in both directions around a horizontal diametrical axis of the needle cylinder, in position located above the machine plates; means for making said semi-circular sector integral with the cylinder to needles, with a radial shutter sliding between two positions, blocking and respectively unlocking the sector relative to
  • the above-mentioned process even if it makes it possible to produce a finished finished product of good quality, includes the necessity of leaving the knitting needles inserted, which support the stitches of the manufactured product during the remeshing phase, inside the loops which constitute the stitches, as well as the union line of the edges of the manufactured product results slightly dilated.
  • the stitching pitch of the aforementioned edges is equal to that of knitting, rather than inferior, as on the other hand it is necessary to obtain a tighter and elastic seam and thus to produce a product of better quality.
  • the device for carrying out this previously known process has a very complex construction, especially in relation to the large number of elements placed in correspondence with the textile head of the circular machine.
  • the circular machines for the basic knitting of the manufactured product must be suitably adapted, under the architectural profile, under the structural mechanical profile and finally under the functional profile, for the specific arrangement of the means adopted for carry out the above method of closing the point.
  • this represents a penalty due to the limitation of the degree of interchangeability of the device which, therefore, must be designed in relation to the specific knitting machine for which it is intended.
  • the main aim of the present invention is to eliminate the drawbacks which derive from traditional operational methodologies and to propose a method and an automatic device for joining two edges of a knitted tubular manufactured product which make it possible to obtain a finished manufactured product of superior quality and at the same time, to achieve a great functional simplification as regards the manufacture and handling of the device for remeshing and of the machine for knitting.
  • a stitch is heard in the retained position when it, engaged on a needle valve, is found at a level between the staple of the needle and the free end of the valve in a completely opened.
  • it is planned to insert the final part of the remeshing wire inside the manufactured product, after the execution of the closing nodes of the chain.
  • the remeshing wire can be the same used for knitting the manufactured product, with no continuity, like a different yarn, fed by a corresponding spool, separated from that of the knitting yarn.
  • means are provided for inserting the final part of the remeshing wire which results, connected to the manufactured product, inside the latter.
  • the advantages obtained thanks to the present invention essentially consist in the fact that it is possible to effect the closure of the tip of a knitted tubular manufactured product, on the same machine which produces them, thus obtaining a great reduction in the time and cost of manufacture; which are completely eliminated from certain phases of the traditional process of closing the tip of knitted tubular manufactured products, such as for example the formation of the throwing discard and the corresponding waste, the transfer of the manufactured products from the circular machine to the storage stores or to the machines sewing or remeshing, turning them over, sewing the point and successive straightening; that it is possible to automatically remesh the edges of the manufactured product outside the knitting station and place the remeshing means at a predetermined distance from the latter, while producing a single productive unit; that it is possible to obtain a high degree of accessibility to the means of the knitting station and to those of the remeshing station, as also to the means
