A variable or steady yarn feeding apparatus comprises a first yarn brake; a support; a steady yarn supply drum for plain knitting; a variable yarn supply drum having a high friction resilient V-shaped or U-shaped surface, the drums both driven by a drive device; a yarn guide device for guiding the yarn from the variable yarn supply drum to the steady yarn supply drum; a self-adjustable yarn guide device provided below the support; and a second yarn brake for adjusting the yarn feed of the variable yarn supply drum. An end of the self-adjustable yarn guide device is away from the variable yarn supply drum in a no demand condition by an expansion of a spring provided therein, while the end is in contact with the surfaces of the variable yarn supply drum when there is a yarn demand. A jacquard knitting is made possible by the cooperation of the second yarn brake with the variable yarn supply drum.
