    Abstract: A circular warp knitting machine is designed for knitting hosiery pieces and comprises a stationary needle cylinder, knitting needles which are installed in grooves of two concentrically arranged annular guide bars, racking mechanisms for racking the guide bars together with the guide needles along the front of the knitting needles and rocking mechanisms for rocking the guide needles between the knitting needles. The needle cylinder accomodates a sleeve movable therealong which controls the movement of the sinkers. A holder movable along the needle cylinder is arranged inside the needle cylinder and carries the knitting needles mounted therein, and sliding frames of the rocking mechanisms of the guide needles and concentrically arranged rotatable casings carrying the annular guide bars are installed over the needle cylinder coaxially therewith. This arrangement ensures a simple and compact structure of the machine.
