Definitions

  • the invention relates to a knitting machine needle and a Needle set containing at least one such knitting machine needle contains.
  • From DE-OS 24 08 567 is a knitting machine needle known whose needle body between the hook and the foot as meandering web is formed. They show an improved Lifespan.
  • a needle is known from DE 28 20 925 A1, whose needle body between the foot and the hook by a Double deflected bridge is formed. Parts of the bridge point a changing height.
  • the knitting machine needle according to the invention has a Needle body with a web-like, between the foot and on the hook extending section, which with a Deflection, which is also referred to as Telanderbogen provided is.
  • a Deflection which is also referred to as Telanderbogen provided is.
  • This recess gives the deflection a special resilience and damping effect. It has proved to be the required Stability of the needle shaft and on the other hand The tendency to break hooks even with strong shock loads the needle is drastically reduced. It can be thereby the life of the affected knitting machine needles increase significantly. This is especially true for needle families or needle sets in which individual needles low Have foot-hook spacing. Especially with such needles, at which only a single meander arc, i. A single one Deflection between the foot and the needle is present The recess proves to be particularly positive in terms of the life and shock resistance.
  • the deflection can by a shaft-shaped shaft portion or by consecutive each straight formed sections (first, second and third Section) which blunt each other or include a right angle.
  • the concerned sections coinciding heights on, taking the height of the first and third sections perpendicular to the back of the needle and the height of the second section preferably to measure approximately parallel to this.
  • the height of the needle body is preferably three to five times the height of the individual sections.
  • the recess formed as a slot and extends interrupted or uninterrupted over the entire diversion.
  • the recess may be longer than the z-shaped redirected area, i. she can divert the deflected area to one or both sides In particular, it may extend into or below the range of the foot.
  • the recess may also consist of a Row of circular recesses or otherwise shaped Recesses are provided. It is possible both Form slit as a complete, open breakthrough than also this with a dampening (energy-consuming) material to fill. Alternatively, it is possible not to use the slot as complete breakthrough but merely as one or form bilateral countersink or gutter. Such embodiments lead to a slightly higher shaft stiffness as complete breakthrough embodiments.
  • the inventive Needle several diversions or meanders and several feet exhibit. It has proved to be advantageous that depends on the parameters in the knitting machine and the knitting conditions individual deflections regardless of their Position provided to foot with recesses according to the invention are. In other cases, all deflections with inventive Recesses be provided. This leads to, that needles of a needle family, in different places are provided with recesses according to the invention.
  • FIG. 1 illustrates a knitting machine needle 1, as they especially for fast-running knitting machines can be used.
  • She has a flat Needle body 2, to which a foot 3 with the same thickness connects, the right angle of a narrow, the needle top firmly laying strip-shaped surface 4 projects away. Parallel to this is on the opposite side of the Needle body 2 a narrow strip-shaped needle back 5 educated.
  • Both the surface 4 and the needle back 5 are interrupted by recesses 6, 7, 8, 9 and that way, that the needle body 2 to a certain extent by meandering together subsequent webs 11, 12, 13, 14 is formed.
  • the Height NH of the needle body extends from the surface 4 to to the needle back 5.
  • the needle body 2 To the needle body 2 includes a shaft 15, the end carries a hook 16.
  • the shaft 15 is straight trained and rejuvenated at its end to the Hook 16 out.
  • one can be swiveled mounted tongue 17 may be provided.
  • a deflection 18 (meander) is formed, the bridge 11 with the offset parallel to him Shank 15 connects.
  • the diversion includes a first section 21, a second section 22 and a third section 23, wherein the portion 21 part of the shaft 15 and the section 23 is part of the web 11.
  • the sections 21, 22, 23 close each each about a right angle and they point, as shown in Figure 3, approximately the same height H up.
  • the height H is for the first Section 21 and for the third section 23 perpendicular to the needle back 5 and for the second portion 22 approximately parallel to measure the needle back 5.
  • the length of the section 22, between the surface 4 and the needle back. 5 is to measure, is preferably three to five times the height H of the needle shaft 15.
  • a recess extends 24, preferably centrally through the respective section 21, 22, 23.
  • the recess 24 may be formed as a slot, which completely breaks the needle body. This is for example illustrated in Figure 6, which is a vertical section through the section 23 illustrates.
  • the recess 24 opens here at both flat sides 25, 26 of the needle body 2. Similarly the section through the sections 21 and 22 looks.
  • the recess 24 forming slot can, as Figure 3 illustrated to be s-shaped.
  • the slit ends preferably connect to circular openings 27, 28, which should avoid a concentration of stress at the end of the slot.
  • the slot In the area of the transitions between sections 21, 22 and 22 and 23, the slot can be rounded S-shaped be.
  • the rounding radii R are preferably larger as the width of the parallelflankig limited slot.
  • the Width of the slot is also preferably less than the width of the above and below the slot existing Webs 31, 32. It is possible, the slot width as far as reduce the slot to a joint at which the Webs 31, 32 abut each other. However, it is preferred that this, as Figure 3 illustrates, between each other leave a space.
  • the knitting machine needle 1 described so far works as follows:
  • Figure 2 illustrates a needle family 33, to which different Knitting machine needles 1, 34, 35, 36 belong. While the knitting machine needle 1 with the above Knitting machine needle coincide, indicate the knitting machine needles 34, 35, 36 no slotted deflection. Much more are their needle body only with closed Deflections provided so that they meandering overall are formed.
  • the knitting machine needles 34, 35, 36 differ from the knitting machine needle 1 by the number the deflections between the respective foot 3 and the respective Hook 16.
  • the needle family 33 thus has at least that knitting machine needle 1, in which only a deflection 18 between the foot 3 and the hook 16 is provided is, a corresponding, extending over the deflection 18 Recess 24.
  • the other knitting machine needles 34, 35, 36 may, but need not, be provided with recesses be.
  • a needle set formed from such a needle family 33 Overall, a high load capacity and durability on.
  • the life of the knitting machine needle 1, in which the foot 3 the hook 16 compared to the other Knitting machine needles 34, 35, 36 is closest not less than the life of the other knitting machine needles 34, 35, 36.
  • FIG. 4 illustrates a modified embodiment the knitting machine needle 1.
  • All recesses 24, 37, 38 are each as a slot formed longitudinally in the respective section 21, 22, 23 are arranged. Between the straight slots 37, 24, 38 there is a distance, which is approximately the same big is like a slit width.
  • the recesses 37, 24, 38 can also be arranged across sections. So can For example, the recess 38 from the section 23 in the section 22 protrude and the recess 37 from the section 21 can into the section 22 protrude.
  • the recess 24 may by section 21 over the section 22 to the section 23 protrude. In each of these described arrangements, the corresponding ones are Recesses corresponding to each other at a distance arranged.
  • a further modified embodiment illustrates In this case, the section 22 closes with the adjacent Sections 21, 23 each have an obtuse angle.
  • the recess 24 is predominantly as preferably straighter Slot arranged in the section 22. She can too still with curved ends in the sections 21, 23 into it extend.
  • further recesses 41, 42, 43, 44, 45, 46 e.g. formed in the form of circular openings, the diameter of which is approximately equal to the slot width of the recess 24 matches.
  • this knitting machine needle points in the region of its deflection 18 an improved compliance and it is less susceptible to hard breaks than comparable ones Knitting machine needles without in the field of deflection 18 trained recesses.
  • All recesses of the above-described knitting machine needles may be open as shown in FIG. It is, however possible, this in accordance with Figure 7 wholly or partially with a To provide filling 47, which consists of damping material.
  • This may be a plastic, a natural, elastomer, rubber or a metal that is different from the metal, from which the rest of the knitting machine needle is formed is. For example, another internal damping, mass, Strength, etc. have.
  • the damping material contributes to the absorption of impact energy when introduced into the knitting machine needle 1 at the foot 3 can be. In particular, it prevents the transmission the impact energy on the hook 16.
  • the recess 24, 37, 38 and 41, 42, 43, 44, 45, 46th can also according to Figure 8 or Figure 9 as non-continuous Be formed recess.
  • the bottom 48 in turn contributes to the stiffening at. It allows it, on both sides of the recess 24 very narrow webs 31, 32 to leave, without the Knitting machine needle thereby in terms of their stability very weakening.
  • On the floor 48 may be similar to FIG 7 shows a respective recess 24 fills damping material to be ordered.
  • a knitting machine needle 1 with one of its needle body 2 away foot 3 and one from the needle body up to a hook 16 extending shaft 15 has a Deflection 18, which is arranged between the hook 16 and the foot 3 is.
  • the deflection 18 is provided with at least one recess 24 provided the characteristic impedance of the deflection 18 changes locally and contributes to the reduction of hook breaks Shock on the foot 3 leads.
