Abstract
The knitting machine with needle selection device has a plurality of needles or sub-needles each having a body with at least one magnetized portion. A selection element faces the magnetized portion and is constituted by a plate which is physically separate from the body of the needle or sub-needle and is made of a material which can be magnetized. The selection device has a magnetizing device which acts controllably upon the selection element of the various needles or sub-needles in order to induce a magnetic interaction between the magnetized portion of the body of the needle or sub-needle and the selection element itself. Actuation cams act on the body of the needle or sub-needle, after the action of the magnetizing device, and cause a diversified actuation of the needle or sub-needle depending on the magnetic interaction induced between the portion of the body of the needle or sub-needle and the selection element.
