Definitions

  • the present invention relates to a double warp knitting machine and more particularly refers to a novel arrangement of the sinker bar.
  • Hitherto double warp knitting machines are 5 provided with a special shaft carrying the'sinker bar.
  • the sinker bar By means of corresponding cams the sinker bar is moved in its operative direction. this construction the sinker bar must, by a corresponding formation of the cam, be held in its position until its period of operation begins.
  • the sinker bar must be placed in a position of rest. Only after this movement of the needle bar'is carried out, the operation of the sinker bar is started.
  • cam levers carrying the sinker bar by means of doublearmed levers pivotally connected to them, are
  • cam levers 6 for the sinker bar II also are With pivotally arranged and these cam levers 6 also are moved by cams not shown in the drawing and fixed upon the cam shaft 4. Journalled in bearings I of the cam levers [are levers carrying the sinkerbar l0. These levers are formed as double-armed levers I, 9. The arms '8 of the double-armed levers 8, S carry the sinker bar 10. The arms 9 of the double-armed levers 8, 9 are, by means of links Ii, connected with lever arms l2 fixed upon the shaft H which carries the locking-in cam levers H. The lockingin cam levers It also are actuated by cams not shown in the drawing and mounted upon the cam shaft 4. I
  • the cam levers for the sinker bar are mounted upon the same shaft as thelevers carrying the needle bar 2, the sinker bar is moved in the same direction as the needle bar.
  • the upand down movements of the sinker bar iii are effected by cams acting upon the cam levers of the sinker bar.
  • the cams acting upon the the locking-in cam levers effect the locking-in movement of the sinkers.
  • a shaft In a double warp knitting machine, a shaft, levers mounted on said shaft, a needle bar carried by said levers, cam levers also mounted on said shaft, double-armed levers pivoted to said cam levers, and a sinker bar carried by said double-armed levers.
  • a double warp knitting machine as set forth in claim 1 in which said double-armed levers carrying said sinker bar are connected by links to lever arms which are mounted upon a shaf carrying the locking-in cam levers.
