A support and control device, intended to be mounted in a circular knitting machine provided with a supporting structure, a rotating component-holding unit, and a plurality of stitch formation components, includes a support body provided with a mounting portion, which allows the device to be mounted to the supporting structure, with a front side and a rear side. The front side faces the component-holding unit and is provided with at least one cam for controlling the plurality of stitch formation components, which defines a guiding path which interacts with respective butts for controlling each of the stitch formation components; the rear side is opposite to the front side and faces the outside of the knitting machine. The device includes at least one through opening between the front side and the rear side, open on the guiding path, which defines an empty space placing at least a portion of the guiding path of the cam in direct communication with the outside of the device, so that the respective butts of the stitch formation components interacting with the cam are facing, and in direct communication with, the empty space.

A device (1), a sinker arrangement (5) and a method for loop-forming are described. The device (1) may include a cylinder (2) with first grooves (3) for needles (4) accommodated in a first groove (3), whereby the needles (4) include a loop forming section, and a sinker ring (27) with second grooves (15) for the sinker arrangement (5). The sinker arrangement (5) may include an actuating section (12) and a loop forming section (7). The loop forming section (7) includes an opening (11), and the sinker arrangements (5) are accommodated in one single second groove (15). The opening (11) may be delimited in the width direction (x) by two side faces (23) and the loop forming section of the needle (4) is movably disposed between the two side faces (23) of the opening (11).

A device and a corresponding method produce a knitted fabric with a knitting machine and a roving drawing and strengthening unit. The device has a roving supply unit with a roving, a stretching unit linked to the roving supply unit, and a spinning nozzle device provided downstream from the stretching unit in a roving conveying direction of the device forming a fiber strengthening segment by applying compressed air. An end thread gripping roller pair rotatable in opposite directions is provided downstream from the spinning nozzle device in the roving conveying direction delimiting the fiber strengthening segment. The device has a blow-off device for blowing off the spinning nozzle device and/or the stretching unit and a suction device for suctioning off loose fibers from the spinning nozzle device and/or the stretching unit. The suction device and the blow-off device are interconnected in a blow-off and suction system.

A knitting action parts structure comprises a channel space, a needle walls assembly, a cams assembly, and knitting tools. The knitting tools are positioned within the needle walls assembly, facing the cams assembly to form the channel space. At least one cams assembly part faces a needle walls assembly part and a knitting tools part to form a gradually expanding channel spaces part. During the manufacturing of these parts, product quality is improved without the requirement for additional equipment or complex procedures. When producing fabrics with knitting machines, it prevents fabric contamination and optimizes heat dissipation performance without the requirement for additional energy-consuming devices, thus reducing waste caused by defective products and extending the lifespan of related parts.

A support and control device to be mounted in a circular knitting machine provided with a supporting structure, a rotating component-holding unit, and a plurality of stitch formation components, includes a support body provided with a mounting portion having a front side and a rear side. The front side faces the component-holding unit and is provided with at least one cam defining a guiding path which interacts with respective butts of the stitch formation components. The device includes at least one through opening between the front side and the rear side, open on the guiding path, which defines an empty space placing the guiding path of the cam in direct communication with an outside of the device, so that the respective butts of the stitch formation components are facing, and in direct communication with, the empty space.
