Definitions

  • the invention relates to a cam assembly for knitting machines, particularly to fix the cams in the cam blocks in knitting machines.
  • Cam elements which limit the tracks of needle or sinker butts are normally fixed to carrying members by screws or rivets, while adjustment of their position is performed by pins or other screws which must be positioned very precisely.
  • For changing the cam elements it is necessary to unscrew and to screw a number, in case of multi-track machines a large number of screws.
  • Another disadvantage is that precise reproducibility of the position of cam elements is not guaranteed and that exchanged cam ele­ments must be checked and adjusted. Said exchange of cams is laborious and time demanding.
  • a recess in the cam block is disposed from the side of the needle bed of the machine, said recess being limited by upper and lower walls, side walls and rear wall, in said recess there are cams provided with through-holes through which passes an only one fixing screw holding the cams in the cam block.
  • the upper and lower walls of the recess in the cam block limit the height position of cylinder cams and the side walls of the recess limit the angular position of cylinder cams.
  • the right and left walls of the recess in the cam block limit radial posi­tion of dial cams, not shown side walls limit angular position of dial cams.
  • cams 8 to 11 cooperating with knitting elements 7, 24, 25, 26 in a cylinder 12 are located in a recess 14, in a cam block 1 which is fixed to a clyinder cams carrier 22.
  • the recess 14 is made in the cam block 1 from the side of the cylinder 12 and said recess 14 is limited by an upper wall 2, a lower wall 3, side walls 4 and 5 and a rear wall 6.
  • the upper wall 2 and the lower wall 3 of the recess 14 in the cam block 1 limit the height position of cams 8 to 11 and the side walls 4, 5 limit the angular position of the cams 8 to 11.
  • the cams 8 to 11 are fixed to the cam block 1 by only one fixing element, in this exemplary embodiment by only one screw 13 which passes through the through-holes 15 made in the cams 8 to 11 and screwed into the cam block 1. Between the screw 13 and the wall of the through-hole 15 in the cams there is a gap which permits a motion of the cams between the knitting elements 7, 24, 25, 26 in the cylinder 12 and the rear wall 6 of the recess 14.
  • the screw 13 passing the cams 8 to 11 and screwed into the cam block 1 prevents a releasing of the cams 8 to 11 from the recess 14 when the cam block 1 is taken out from the cylinder cams carrier 22.
  • cams 16, 17 cooperating with knitting elements 19 and 23 in a dial or in a sinker ring 18 fixed to a dial carrier 20, are located in a recess 14 in a cam block 1 which is fixed to the dial cams carrier 21.
  • the recess 14 is made in the cam block 1 from the side of the dial 18 and it is limited by right wall 2, left wall 3, not shown side walls and upper wall 6.
  • the cams 16, 17 are fixed to the cam block by only one screw 13 which passes through the through-holes 15 made in the cams 16, 17 screwed into the cam block 1.
  • a clearance be­tween the screw 13 and the wall of the through-hole 15 permits motion of cams 16, 17 between the knitting ele­ments 19, 23 in the dial 18 and the upper wall 6 of the recess 14 in the cam block 1.
  • Radial position of the cams 16, 17 is limited by walls 2 and 3 of the recess 14 in the cam block 1, angular position of the cams 16, 17 is limited by not shown side walls of the recess 14 in the cam block 1.
