ABSTRACT:
A unit is disclosed for transmitting motion to the hosiery suction tube in a circular knitting machine of the type having a fixed supporting plate to which a cylinder support with a vertical axis, an internal hosiery passage tube that is coaxial to the cylinder support, and an underlying perforated tube are rotatably coupled. The unit has respective flanges rigidly coupled below the cylinder support and above the perforated tube and supporting respective pluralities of permanent magnets that are distributed in an annular fashion and constitute a magnetic coupling between the flanges for the rotary actuation of the perforated tube. A collar of a material that has high magnetic reluctance is arranged in the air gap formed between the rings of facing magnets and has a device for rotary coupling to the hosiery passage and a device for selective coupling to said flanges or to said fixed supporting plate for causing or stopping the rotation of the hosiery passage tube.
