Definitions

  • the present invention relates to a composite needle or sliding needle, particularly for rectilinear knitting machines.
  • sliding needles are generally constituted by a needle body that forms, at one of its ends, the hook-like portion, on which a slider can slide; the front end of the slider forms the latch for closing the hook-like portion and the stitch transfer element.
  • the slider can also be constituted in practice by a pair of laminas arranged side by side within the body of the needle, which has a substantially U-shaped cross-section.
  • the laminas are mutually compressed at their free end, and this situation inevitably causes an accumulation of dirt that is difficult to remove.
  • the aim of the invention is indeed to eliminate the drawbacks noted above by providing a composite needle, particularly for rectilinear knitting machines, that is structured so that it is of the self-cleaning type, i.e., capable of removing continuously the dirt that inevitably accumulates in the needle working area.
  • an object of the invention is to provide a composite needle that is suitable for application in conventional rectilinear knitting machines while having optimized characteristics.
  • Another object of the present invention is to provide a composite needle that thanks to its particular constructive characteristics is capable of giving the greatest assurances of reliability and safety in use.
  • Another object of the present invention is to provide a composite needle particularly for rectilinear knitting machines that can be obtained easily starting from commonly commercially available elements and materials and is further competitive from a merely economical standpoint.
  • a composite needle particularly for rectilinear knitting machines which comprises a needle body that forms a hook-like portion at one end and a slider that can slidingly engage said needle body, characterized in that said needle body has, in a central portion, an I-shaped transverse cross-section that forms two slots that slidingly accommodate laminas that form said slider, said needle body, proximate to the end that forms said hook-like portion, having means for divaricating said laminas in the extracted position with respect to said needle body.
  • a composite needle particularly for rectilinear knitting machines which is generally designated by the reference numeral 1 and has a needle body 2 that forms, at one of its ends, a hook-like or curved portion 3.
  • a slider 4 that can slide with respect to the needle body 2 is provided.
  • the needle body 2 has in transverse cross-section, as shown more clearly in Figure 17, a substantially I-shaped configuration, with two lateral slots 10 and 11 that contain the laminas 12 and 13 and form the slider.
  • the laminas as shown more clearly in Figures 5 and 6, end with a tab-shaped portion 20, which is bent toward the central body 21 of the needle body 2.
  • recesses 25 are provided that allow to accommodate the tabs 20 with the slider in the retracted position.
  • the recesses 25 have, at the end directed toward the hook-shaped portion 3, wider portions 26, and there are also divaricating means provided as divaricating elements 27 at the end of the slots 10 and 11 which are designed to space one another the laminas 12 and 13, which remain in the spaced position even when they are arranged in the extracted position.
  • the laminas have a tooth 30-for engaging the stitch, which acts as an element for removing any dirt particles.
  • the solution adopted provides in practice a continuous scraping on the laminas that facilitates cleaning.
  • Figures 9 to 16 illustrate a needle, designated by the reference numeral 100, the needle body 101 of which has a central portion that has a solution that is fully comparable to the one shown in Figure 17 and a slider 102 that is formed by two laminas 103 and 104, which can slide in the slots formed by the needle body.
  • the needle body 101 forms two shaped side walls or shoulders 110, which delimit a central passage 111 through which the laminas 103 and 104 are passed during extraction and, by elastic flexing, are divaricated by the portion 105, as shown in Figure 16.
  • the laminas in their motion, due to the presence of a similar tooth 120 on the laminas, remove the dirt; moreover, when crossing other needles, as shown in Figures 18 and 19, any dirt between the laminas is expelled therefrom.
  • the described arrangement performs a scraping effect on the laminas that allows to have always an optimum level of cleanness.
  • the composite needle according to the invention is particularly flexible thanks to the adoption of a needle body that has an I-shaped cross-section, which allows to better guide the laminas without stiffening the assembly.
  • the materials used, as well as the contingent shapes and dimensions may be any according to requirements.
