ABSTRACT:
In a circular knitting machine, a cam drum which controls control members co-operating with the needle cylinder is disposed coaxially with the cylinder. A program drum which advances as a function of the rotation of the needle cylinder is also coaxial with the needle cylinder. A rapid control mechanism acts on a ratchet toothed ring gear of the program drum to change the programmed cycle phases and to move it to a zero position, that is a cycle commencement position. A control device acts on a ring gear for the advancement of the cam drum and is activated when the program drum attains the zero position in order to also move the cam drum into the zero position.
