ABSTRACT:
In a yarn feeding device with constant adjustable tension, for use in weaving and knitting machines, of the type comprising a fixed hollow body around which the yarn to be fed is wound by an external rotary element, to form thereon a yarn reserve from which the yarn is drawn to be sent to said weaving or knitting machine, passing through the inside of said fixed hollow body, a brake is provided which acts by pressing the yarn onto the edge of the said fixed body. The brake comprises a plurality of substantially radial elements of thin sheet-metal, held at the ends between an outer ring and a central hub of plastic material, which are moreover connected to each other by radial elastic laminae, said substantially radial elements being designed to be pressed onto the edge of the fixed body of said feeding device, to brake the yarn thereon thanks to the action of an adjustable setscrew which freely engages the center of said central hub, said outer ring being arranged beyond the edge of said fixed body.
