Abstract
A variable and steady yarn feeding apparatus is disclosed. The apparatus comprises a support; a drive device; a steady yarn supply drum for plain knitting; a variable yarn supply drum having a number of high friction resilient yarn guide surfaces, the variable yarn supply drum and steady yarn supply drum both driven by the 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 yarn brake for adjusting the yarn feed of the variable yarn supply drum. An end of a self-adjustable yarn guide device is away from the variable yarn supply drum when there is no yarn demand condition by an expansion of a spring provided therein, while the end of the self-adjustable yarn guide device 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 yarn brake with the variable yarn supply drum.
