Abstract
The device has a box-like supporting structure which slidably accommodates at least one slider arranged laterally facing the needle cylinder of the machine and is movable, by virtue of the action of a linear motor, along a direction which is radial to the needle cylinder. The slider is rigidly associated, with its end which protrudes out of the box-like structure, with a knitting cam which is selectively engageable with needle actuation elements by moving the slider. The slider is constituted by a shaft which is slidably supported, along its axis, by the box-like structure by means of a first bearing which is arranged inside the box-like structure and has balls partially accommodated in longitudinal seats defined on the outer surface of the shaft and in seats correspondingly defined on the inner surface of a bush which extends around the shaft and is prevented from rotating about its axis.
