Circular hosiery knitting machine, particularly of the double cylinder type, with yarn finger for plated knitting

A circular hosiery knitting machine with yarn finger for plated knitting, comprising at least one needle cylinder that has a plurality of axial grooves that each accommodate a needle, said needle cylinder being actuatable with a rotary motion about its own axis, arranged vertically, with respect to at least one feed or drop at which there are at least two yarn fingers for plated knitting, respectively a first yarn finger for dispensing a base yarn and a second yarn finger for dispensing a reinforcement yarn, said second yarn finger having an elongated body that comprises a dispensing end, located proximate to a longitudinal end thereof and provided with a passage for the reinforcement yarn to be dispensed to the needles of the machine arranged in said needle cylinder, and a remaining part of the body of the second yarn finger;

• said second yarn finger being arrangeable so that said dispensing end thereof faces laterally the needle cylinder in the working area of the needles, wherein said dispensing end of the body of the second yarn finger can move on command with respect to the remaining part of the body of the second yarn finger, on a plane that is substantially perpendicular to the axis of the needle cylinder, along a direction that is substantially parallel to the tangent to said needle cylinder in a grip point, by the needles, of said reinforcement yarn dispensed by said second yarn finger.
