A CIRCULAR KNITTING MACHINE WITH AN OFFSET SYSTEM FOR THE STITCH CAM OF THE NEEDLE PLATE

A circular knitting machine for knitted items, comprising: a supporting structure; a needle-holding cylinder selectively turnable and provided with a plurality of cylinder needles; and a dial assembly. The dial assembly includes a supporting ring integral with the supporting structure; a needle-holding plate turnably mounted to the supporting ring; a plurality of plate needles; a plurality of control cams which interact with the plate needles to transmit to them a radial movement inside the respective sliding seat, wherein the control cams globally form a cam profile. The dial assembly includes a stitch cam placed movably on the supporting ring and interacting with the plate needles in a given angular sector during the rotation of the needle-holding plate, so as to transmit to the plate needles a motion of return for executing stitch formation. The stitch cam is selectively movable with respect to the cam profile.
