Definitions

  • the invention relates to a thread guide for flat knitting machines according to the preamble of claim 1.
  • Thread guide bracket arranged the the knitting thread Feeds knitting needles.
  • the thread guide bracket points in the Usually a first eyelet at its upper end and at its lower end Open a second eyelet.
  • the Knitting thread that is fed from a bobbin by approx. 90 ° from a horizontal position to a vertical position the thread guide bracket deflected.
  • On the eyelet at the top of the The thread guide bracket undergoes a further deflection the vertical direction in the direction of withdrawal of the thread, the from the relative position of the thread guide bracket tip to Knitting needle is determined.
  • the two deflection points of the thread in the two eyelets of the thread guide bracket cause the Knitting thread due to the friction in the eyelets receives increasingly higher thread tension.
  • This voltage increase depends heavily on the properties of the knitting thread, i.e. H. its Elasticity, its thickness and its surface quality as well as the length of the thread at the eyes and is therefore difficult to control.
  • Especially at Elastic threads can increase the thread tension through the two Deflecting the thread guide bracket to problems with knitting to lead.
  • the present invention is based on the object Propose thread guide, in which the increase in thread tension significantly reduced compared to the known thread guides is.
  • the central axis of the thread guide can also the friction, that of the knitting thread on the at the tip of the thread guide bracket arranged guide eyelet experiences, be reduced.
  • the guide roller the thread at the top of the Guide the guide eyelet located in such a way that the thread section fed to the eyelet with that from the eyelet outgoing thread section includes a flat angle. This leads to the fact that the contact length of the knitting thread on the Guide eyelet compared to conventional thread guides, where one Deflection of the knitting thread in the guide eyelet by approximately 90 ° takes place, is reduced.
  • the horizontal distance can be used to optimally adjust the angle the thread deflection roller to the vertical central axis of the thread guide preferably be adjustable. To achieve a optimal thread tension, it is also necessary that the Deflection roller leading in the direction of movement of the thread guide is arranged in front of the central axis of the thread guide.
  • the pulley is driven by a mechanism with the thread guide drive coupled so that the optimal position of the pulley depending on the position of the thread guide automatically sets.
  • the pulley should also if possible be low friction. To do this, it is advantageous if the deflection roller is stored with a low rolling friction and from is made of a light material. Regardless of the length of the wrap the knitting thread thus becomes the thread tension of the knitting thread hardly increased by the deflection roller.
  • the thread guide 1 according to the prior art according to FIG. 1 has a thread guide carriage 2 and an arranged thereon Thread guide bracket 3.
  • the thread guide carriage 2 moves turn left in the direction of arrow 60.
  • the thread guide bracket 3 has an upper eyelet 4 and a lower eyelet 5 for a knitting thread 10.
  • the sections of the knitting thread 10 in front of the eyelet 4, between the eyelets 4 and 5 and between the Eyelet 5 and a knitting needle 100 are with 10 ', 10' 'and 10' '' characterized.
  • the upper eyelet 4 forms a deflection point 40 for the knitting thread 10, whereby the knitting thread 10 deflects from approximately 90 ° from the horizontal to the vertical (Thread section 10 ").
  • Knitting thread 10 On the second eyelet 5 the Knitting thread 10 again at the deflection point 50 by approximately 90 ° diverted.
  • the angle of the Knitting thread section 10 '' 'with the vertical is marked with 30.
  • the knitting thread 10 experiences on the Deflection point 50 a deflection by an overall angle, which is composed of the angles 20 and 30.
  • FIGS. 2 and 3 of a thread guide 11 according to the invention which also has a thread guide carriage 21 and one Has thread guide bracket 31.
  • the thread guide bracket 31 has here, however, an eyelet 51 only at its tip. At the top No eyelet is provided in the area. There is a pulley for this 41 available for the knitting thread 10.
  • the deflection roller 41 is in the direction of movement of the thread guide 11 by the distance A. laterally offset from its central axis 71.
  • the distance A of the pulley 41 from the Center axis 71 is adjustable so that depending on what is used Knitting thread 10 an optimal angle between the knitting thread sections 10 '' and 10 '' 'is adjustable.
  • the pulley 41 is very light and on an axis 61 with low friction stored so that only an extremely small increase in Thread tension of the knitting thread 10 arises.
  • the deflection roller 41 is not closer to here mechanics shown coupled with the drive of the thread guide 11, so that automatically when the direction of movement is reversed of the thread guide 11 the position shown in Fig. 3 the pulley 41 adjusts. It is now in the direction of movement 70 of the thread guide 11 leading by the distance A arranged offset to the central axis 71. This also arises again the same angle between the thread sections 10 '' and 10 '' 'a.
  • the contact length of the knitting thread 10 on the Deflection roller 41 is less than in the arrangement of the deflection roller 41 according to FIG. 2, however, this relates to the thread tension does not affect, since the friction on the deflection roller 41 independently of the loop length of the knitting thread 10.
