Definitions

  • the present invention relates to a method for forming hosiery items or tubular knitted items having a closed end with a circular hosiery knitting machine.
  • European Patent Application No. 96111186.1 in the name of the same Applicant discloses a method which uses a single-cylinder circular machine having, at the upper end of the needle cylinder, a half-dial which faces one half of the needle cylinder and is provided with elements for taking up the thread which can be actuated in a direction which is radial to the needle cylinder and are suitable to engage the thread or threads fed at a feed of the machine, in the region between two contiguous needles.
  • Said half-dial can be turned over, about a diametrical axis of the needle cylinder, in order to face the other half of the needle cylinder.
  • This method comprises a first step, during which the needle cylinder is actuated with n oscillations about its own axis with an oscillation angle of substantially 180 o in order to move the needle cylinder half faced by the half-dial so that it passes in front of a feed of the machine.
  • the takeup elements are extracted radially with one of their ends from the half-dial towards the needles of the machine, and at least one thread is dispensed at said feed, lifting into the active position, at each oscillation, 1/n of the needles of said needle cylinder half which are uniformly spaced from each other, varying the needles that are moved into the active position in the subsequent oscillation or oscillations and lowering the needles after taking up the thread or threads, resting on the takeup elements.
  • a second step is performed during which the takeup elements are retracted into the half-dial, retaining the thread or threads rested thereon.
  • heel knitting is performed with the needles of said needle cylinder half.
  • a fourth step the half-dial is turned over about the diametrical axis and is arranged so as to face the other half of the needle cylinder. Then a fifth step is performed during which the thread or threads held previously by the takeup elements are transferred to the needles of the other half of the needle cylinder. Finally, in a sixth step, the machine is actuated so as to complete the tubular item as a continuation of the previously performed knitting.
  • the half-dial used to perform the method according to the above cited patent application covers an angle of substantially 180 o about the axis of the needle cylinder and has a grip element, substantially constituted by a hook, for each one of the needles of one half of the needle cylinder.
  • the hooks of the half-dial are all extracted from the half-dial, so that each one arranges itself between two contiguous needles of one half of the needle cylinder.
  • the thread dispensed during the oscillations of the needle cylinder about its own axis rests on all the hooks of the half-dial and remains engaged with them at the end of the second step.
  • Italian Patent application no. BO96A-00533 in the name of the same Applicant discloses another method for manufacturing hosiery items or tubular items in general having a closed end with a single-cylinder circular machine.
  • the method disclosed in this Italian patent application comprises at least one first step, during which the needle cylinder is rotated alternately about its own axis to form a pouch with heel knitting, or end, using a set of needles located in one half of the needle cylinder, and a second step, during which the needle cylinder is actuated with a continuous motion to form a tubular portion of the item.
  • At least one of the initial rows of knitting formed during the first step which at the end of the first step is inside the needle cylinder and is arranged along a chord which lies between the two end needles of the set of needles used during the first step, is engaged, through an auxiliary element which is hook-shaped, starting from one of the two end needles, and gradually moved above the needles located in the other half of the needle cylinder and knitted in by them with the first row of knitting formed at the beginning of the second step.
  • the aim of the present invention is to solve the above described problems by providing a method which allows to produce hosiery items, or tubular items, having a closed end with a circular hosiery knitting machine, leading to a result, in the closure of the end of the item, which is fully satisfactory both technically and aesthetically.
  • an object of the present invention is to provide a method that can be adopted without problems even if the end of the item is formed with a reduced number of rows.
  • the method according to the invention is meant to be performed with a circular hosiery knitting machine, for example a single-cylinder circular machine having, proximate to the needle work area, a transfer element which is constituted for example, as described in European patent application No. 96111186.1, by a half-dial which faces one half of the needle cylinder and has thread takeup elements constituted for example by hooks which can be actuated radially with respect to the needle cylinder and are suitable to engage the thread or threads fed by at least one feed of the machine in the region between two contiguous needles.
  • Said transfer element can be turned over about a diametrical axis of the needle cylinder.
  • the transfer element has not been illustrated for the sake of clarity; as mentioned, said transfer element can be constituted by a half-dial of the type described in the prior above-cited patent application; only some of the takeup elements, constituted by hooks 1, have been illustrated.
  • the needle cylinder has not been illustrated and only some of the needles 2a of a first half 3a of the needle cylinder and some of the needles 2b of the second half 3b of the needle cylinder have been shown.
  • said half-dial has a number of hooks 1 which is equal to, or smaller than, the number of needles of one half of the needle cylinder.
  • the angular spacing of the various hooks 1 is such that each hook 1 is positioned between two contiguous needles of the needle cylinder.
  • the hooks 1 can be equal in number to the needles of one half of the needle cylinder, or their number may be smaller, in that two regions of the half-dial that are located proximate to its lateral ends and cover an angle ⁇ may be without hooks 1, as will become apparent hereinafter.
  • the transfer element faces the first half 3a of the needle cylinder and is actuated, together with the needle cylinder, with n oscillations about the axis 5 of the needle cylinder with an oscillation angle of substantially 180 o , so that the first half 3a of the needle cylinder passes entirely in front of a feed of the machine whereat one or more threads are fed according to requirements.
  • the takeup elements or hooks 1 of the transfer element are extracted radially from said transfer element so as to be arranged between two contiguous needles 2a of the first half 3a of the needle cylinder.
  • takeup elements or hooks 1 belonging to a sector of the transfer element that is narrower than 180 o are extracted. More particularly, if the transfer element has no hooks 1 at the two end sectors that cover an angle ⁇ , all the hooks 1 are extracted; or, if the transfer element has takeup elements or hooks 1 over its entire extension, i.e., along substantially 180 o around the axis 5 of the needle cylinder, the hooks that belong to the end sectors which cover an angle ⁇ are kept retracted.
  • the takeup elements or hooks 1 located in a sector of the transfer element that covers an angle of substantially 180 o -2 ⁇ around the needle cylinder axis 5 are extracted, as shown in figures 3 to 5.
  • the sector that covers an angle 180 o -2 ⁇ is distributed symmetrically with respect to the diameter of the needle cylinder that is perpendicular to the diametrical axis 7 about which the transfer element is turned over.
  • the needles 2b after taking up the thread, are lowered so as to form a loop of knitting with the thread or threads fed at the feed being considered and the thread, between two contiguous needles moved into the active position, rests on the takeup elements or hooks 1 that are extracted from the transfer element.
  • the thread or threads fed during the n oscillations is, or are, always the same thread or threads.
  • Said thread may be an elastic thread.
  • the number of oscillations is between 1 (in that the needle cylinder might be actuated, during this first step, with a simple forward stroke with a 180 o rotation about its own axis) and 5.
  • the takeup elements or hooks 1 are retracted into the transfer element, so as to retain the thread or threads rested on said takeup elements.
  • the needle cylinder is rotated alternately about the axis 5a so as to perform, with the needles 2a of the first half 3a of the needle cylinder, heel knitting which will constitute the end 10 of the item 11.
  • the transfer element or half-dial is turned over about the diametrical axis 7 so as to face the second half 3b of the needle cylinder.
  • the takeup elements or hooks 1 are extracted radially from the transfer element and the needles 2b of the second half 3b of the needle cylinder, which face said takeup elements 1, are lifted and then lowered, while the takeup elements 1 are again retracted into the transfer element, as described in the prior European patent application No. 96111186.1, so as to transfer the thread or threads retained by the takeup elements 1 to the needles 2b of the second half 3b of the needle cylinder that face said takeup elements.
  • the loops of the first row or rows knitted during the first step are passed from the needles 2a of the first half 3a of the needle cylinder that are located laterally to the sector that covers an angle of 180 o -2 ⁇ , to the needles 2b of the second half 3b of the needle cylinder that are located, after the overturning of the takeup element performed in the fourth step, laterally to the sector that covers an angle of 180 o -2 ⁇ .
  • Said needles are raised so as to engage the loops that are taken up and carried by the hook element 6.
  • the perimetric region of the heel-knit portion or end 10 is therefore engaged both with the needles 2a of the first half 3a of the needle cylinder and with the needles 2b of the second half 3b of the needle cylinder.
  • a sixth step is performed wherein the machine is actuated so as to complete the tubular item as a continuation of the previous processes, in a per se known manner which is not described for the sake of simplicity.
