Patent ID: 7096694

Claim:
A yarn feeding device of a weft knitting machine comprising: at least one pair of needle beds slidably accommodating knitting needles arranged in a front-back direction in a state forming a mouth clearance; a movable knitting member operable in-and-out toward a mouth between the knitting needles of the needle bed; a guide rail having a plurality of yarn feeders slidably provided on the needle bed; entraining means for entraining yarn feeders selected from the plurality of yarn feeders with a sliding drive mechanism; and switching mechanisms provided for each of the plurality of yarn feeders, wherein the switching mechanism includes a push-in operation member switchingly operating the height position of a yarn feeding port in association with the entraining means, and the push-in operation member includes a pressing operation panel setting a yarn feeding position where the yarn feeding port mostly nears the knitting needle and an intermediate position where the yarn feeding port is positioned above the yarn feeding position and nearest the movable knitting member, so that a withdrawal position where the yarn feeding port is not operated by the push-in operation member, the intermediate position, and the yarn feeding position are formed in that order from the top, and wherein the lift of the yarn feeding port is drivingly connected with the forward and backward movements of the movable knitting member so that the movable knitting member is retracted to open the mouth, the yarn feeding port lowers to the yarn feeding position, and at the intermediate position, the movable knitting member moves forward to a mouth clearance portion to close the mouth.
