Abstract
According to the present invention, there is provided a yarn feeding mechanism in a flat knitting machine capable of reliably preventing looseness of knitting yarn on a supply path without increasing the tension of each knitting yarn. The upstream side and the downstream V-groove guide rollers having substantially V-shaped grooves are rotatably supported on the supply path for supplying the knitting yarns to the yarns by the bundles. The axes of the V-groove guide rollers are inclined with respect to the direction orthogonal to the supply path so that the yarns are rotated from the slopes on one side of the slopes of the grooves until the troughs are twisted between the V-groove guide rollers. In addition, the line connecting the troughs of the grooves of the V-groove guide rollers in the circumferential direction becomes a sinusoidal curve of one cycle during the period in which the V-groove guide rollers are rotated for one revolution.
