Definitions

  • thelarge number of threads are led to the needlesby means. of guides, one foreach thread, thelgulde being mounted in one or more guide bars and the guides in each bar being simultaneously and similarly operated.
  • the loperation of the guides involves two kinds of movement, rst1y ⁇ , movements parallel to the length ofthe series of needles by which the threads are'V knitted, either behind the needles soV as lto guide ythe threads from needle to needle behind the needle series,v or in front of the needles to lap the' threads under the beards of the needles, and secondly, movements acrossv theline of the series-of needles, ⁇ from front to rear or from rear to front of the needles.
  • a method of warp knitting comprises knitting a.
  • the means employed according tothe tion for bringing about the necessary motions of inven- 5I the threads comprise.. in addition to the series of guides, disposed always above and in iront of the needles. with' whichthethreads are in constant engagement, a series ofthread-engaging y ,15 elements forl coming intol engagement with the threads at every course and for pushing them across the line/of. the needles.
  • the sinkers ordinarily provided in the machine to act as a support for the 4wifabric and to holddown thefabric each time the needles rise after knitting.
  • a further throat or notch is provided above the level at which the fabric is l5 formed, the s inker being made of suillcient depth to 'provide material forthe formation of a notch.
  • the whole, designof th'e machine is simplified, and in particular the heavy warp beams from which the threads are supplied can be placed lower in the machine so that the centre of gravity of the machine lis kept down. All these factors, viz. the simplification ofthe guide bar movement, the :tact that more time in the cycle is available for it, and the reduced height of the machine, tend to reduce vibration in the machine, and. together with the reduced need for accuracy in the guide bar positioning, enable greater knitting speeds to be achieved.'
