For adjusting loop density in a circular knitting machine there is provided a step motor arranged below the needle cylinder and having a threaded shaft threadably engaging one end of a lever pivoted to a stationary structure of the machine. The free end of the threaded shaft abuts against a rotatable stop supported by the stationary portion of the machine, and the housing of the motor is prevented from rotating with respect to the lever. The opposed end of this lever supports a cylinder holder. Rotation of the threaded shaft of the step motor which is controlled by a programming member causes a pivotal movement of the lever and thus a raising or lowering movement of the needle cylinder to vary the loop density.
