Definitions

  • the present invention refers to a mechanism for the regulation of pressure on the yarn, and the con­sumption of same, in rectilineal knitting machines, a mechanism which structural characteristics have been designed in order that said regulation is carried out automatically, with a perfect self-control in the pre­viously cited variables, that is, in the pressure and yarn consumption, adequate to the specific needs of each time.
  • the threading or travel of the yarn is started in the feeding cones, located on a supporting board and the yarns pass through the upper arms or tensors, through the knot catchers and through the pressure plates, located all of them in the upper part. After this, the yarns pass through the side tensors, loc­ated at the left and right, and therefrom, are dir­ected to the carriers, which are the ones that, de­finitely, locate it in the convenient position for weaving.
  • the mechanism which the invention pro­poses solves this problem at full satisfaction, en­suring a self-control and a self-regulation in the rectilineal knitting machine, to which such a me­chanism is coupled, so that the pressure is regul­ated automatically according to the consumption of yarn, being adequate at each time to the specific needs of same and under optimal conditions from the quantitative point of view.
  • the me­chanism of self-control and regulation which is pre­conized, starts from the classical elements with respect ot a rectilineal knitting machine, that is, to the corresponding upper arms or tensors, with their corresponding knot catchers, of the pressure plates which is precisely where the regulation of sa­id pressure is carried out, and of the side tensors that feed the carriers and which are the ones in char­ge of absorbing the yarn excess, when necessary, like for instance, on the edges.
  • the invention is center­ed on a special and new configuration and disposition for some of these elements.
  • the group of pressure rollers is moved towards the farthest are­as of the machine, to be placed close to the side tensors, as these elements, that is, pressure rollers and side tensors, are intended to work jointly, with a direct action of ones on the others, to attain the effect of automatism pursued.
  • these pressure plates which convention strictlyally are mounted on a support provided with a thread­ed neck are are pressed one against the other by a conical spring, which pressure is manually adjusted with a nut coupled to the said threaded neck, keep­ing these structural elements, incorporate besides, a special washer, located between the conical spring and the corresponding plate, which washer is provided with a central nerve on which, in due time, actuates a small axle, mounted in the hollow inside of the support, and actuated by the corresponding side tensor, as will be seen later on.
  • these side ten­sors adopt a conical configuration, that is, that they present a progressively decreasing section to­wards their free end, in which is located the eye­let for the passing of the yarn towards the "carri­ers" of the carriage, so that their flexibility in­creases progressively towards said free end, and the effective or real moves of the eyelet through which the yarn passes are considerably greater than the tilting of the head of the tensor, in order to attain that the movement of the axle corresponding to the pressure plates be minimal, in accordance with the practical requirements of the type of re­gulation expected.
  • the pressure plates 5, instead of being placed at the top and close to the upper tensors 4, are placed on the sides, at the end areas of the machine, close to the side tensors 6, exactly and as especially observed in figure 1.
  • each group of pressure plates 5 presents, as a special charac­teristic, and that is fundamental for the effect of self-control and automatic regulation which is pretended, the incorporation of a special washer 14, set forth between the conical spring 11 and the couple of plates 5, the existence in said spe­cial washer 14, of a central nerve 15, which crosses the slot or diametral cutting 10 of the shaft 9, and the existence in the support 8 of an axial hole 16, through which enters in its sine an axle 17, which end 18, incides on the cen­ tral nerve 15 of the special washer 14, so that through the movement of the axle 17 one may con­trol the positioning of the special washer 14 and through the latter, control the effect that the conical axle 11 exerts on the couple of plates 5, or what is the same, control and pressure on the yarn that passes between them.
  • each side ten­sor 6 incorporating a head 19, tiltable on an axle 10, common for all the heads of the side ten­sors, as especially observed in figure 6, and which tilting is made against a spring 31 that, at one of its ends, is fastened to the head 19, through the hook 22 or through any other appropri­ate means, whilst on its other end it is fasten­ed to the bedframe 23 which supports all these ten­sion mechanisms and which is as well perfectly vis­ible in figures 5 and 6.
  • this framework 23 in­corporates at the top a transverse bar or axle 24, on which the rollers 25 for guiding for the yarns 3 from the upper tensors 4 toward the pla­tes 5 are mounted, being the supports 8 of the latter mounted on a transverse flatbar 26, under and behind which is located the cited tilting axle 20 for the heads of the side tensors 6.
  • the side tensors 6, as especially observed in figure 4, adopt a conical configuration, that is, their section is decreasing towards their free end, where an eyelet 27 is located, for the guiding of the yarn towards the carriers 7, so that with this conical configuration, the flexibility of the side tensors grows progressively towards said free end. Notwithstanding, the cited tensors could be obtain­ed on basis of cylindrical rods of diameters which progressively decrease towards their free end, as in turn shown in figure 1.
