Definitions

  • This invention relates to improvements in at knitting machines and more particularly to knitting machines which are intended to produce plated goods and utilise a plurality of yarn car- 5 riers for this purpose.
  • An object of this invention is to prevent sinkers which may be deflected by an inaccurately or wrongly positioned yarn carrier or carriers during the sinking of the loops from causing trouble when the nose of said sinkers enters the frame needle division.
  • yarn carriers are permitted to assume inaccurate or wrong positions, but a provision is made enabling for the 'nose portion of sinkers having been deected by inaccurately positioned yarn carriers subsequently to return by its own resiliencelinto the predetermined position prior to its entry into the plane o'f the frame needle shanks.
  • the means for enabling the sinker noses to spring back into their correct positions may consist, for example, in the provision on the upper edge of the sinkers of suitably spaced cuts or incisions inclined with respect to a longitudinal axis, so that between said cuts there are formed lamellae or tongues yielding resiliently in lateral direction.
  • the said resilient members are formed on the sinkers operating within the reach of the yarn carrier end positions in such way that they interfere with the path of the yarn carrier ends when the sinker noses are in a position shortly preceding their entering into the plane of the frame needles.
  • the nose portion of the obstructed sinker will be laterally deflected by engagement with the end of the yarn i carrier during forward motion of the sinker until after a further advance of said sinker its lamella comes into the path of the end of the yarn carrier. At this moment the nose springs back into its correct position, the lamella being then deflected alone.
  • Fig. 1 shows the position of the sinkers before the sinking of the loops
  • Fig. 2 shows the position of the sinkers during the sinking of the loops
  • Fig. 3 is a plan view of the position according to Fig. 2; A
  • Fig. 4 shows another form of the cut.
  • the gures show a portion of the sinker head of a normal fiat knitting machine, the other parts whereof, which are not necessary for understanding the invention, having been omitted.
  • Fig. 1 the bottom rail of the sinker head is shown at I, 2 denotes the cover of the sinker head, 3 the loop or jack sinkers and 4 the dividing sinkers.
  • the guide tube of a yarn carrier is shown at 5, and l are the frame needles of the frame needle bar.
  • a resilient lamella 8 is formed by oblique cuts 9 and lll in the sinker extending downwards from the upper edge thereof.
  • a sinker head embodying a bottom rail member and a cover member and having slidably mounted .therein loop sinkers and dividing sinkers coperating with frame needles and with yarn carrier tubes, the provision on the said loop sinkers of lamellae or tongues formed by cuts extending downwardly from the'upper edges thereof and adapted to be resiliently deected by an inaccurately or wrongly positioned yarn carrier tube or tubes which interfere with the path of said loop sinkers, the nose portions of the sinkers being allowed to spring back into their correct position as soon as they have slipped past and out of engagement with the obstructing yarn carrier tube and prior to their entry into the plane of the frame needle shanks.
  • sinkers of resilient lamellae or tongues formed by oblique cuts in said sinkers extending downwards from the upper edge thereof, the conformation of said cuts being such that by return movement of a sinker the lower end of said cuts enters the sinker bed inst, whereby the return guidance of said lamellae or tongues is assisted and a smooth jerkless return motion thereof is assured.
  • a sinker head embodying a bottom rail member and a cover member and having slidably mounted therein loop sinkers and dividing sinkers cooperating with frame needles and with yarn carrier tubes, the provision on the said loop sinkers of lamellae or tongues formed by a single cut extending downwards in an oblique direction from the upper edge thereof and having its lower end substantially parallel and extending to within a short distance in front of said sinker cover member.
