Abstract: Feeder-stripper device for circular knitting machines, whereby the device can be anchored substantially at a tangent to the needle cylinders and comprises a carrying structure consisting of a plurality of firm supporting surfaces to support the yarn carriers, and whereby the firm supporting surfaces are mutually sloped fan-wise in both a substantially radial direction and a substantially tangential direction in relation to the needle cylinders, whereby the yarn carriers are fitted in a relatively movable manner in relation to the firm surfaces so as to enable their own ends to follow a substantially continuous and curved path during their movement between their working position and their position of rest, and whereby each yarn carrier cooperates with a four-bar positioning and supporting linkage provided with only one degree of freedom and anchored revolvably to their respective firm supporting surface, and whereby suitable actuators rotate the respective linkage, on each of which there act bias elements coop
