Abstract: This device for making tuft figured fabric comprises, between the feed bobbin containing the tufting thread and the fabric to be tufted, a friction roller adapted to be shifted for engaging either of a plurality of cylinders driven at different speeds; said roller is mounted at one end of a rigid support having its opposite end responsive to a snap-action spring having an intermediate unstable position; the support is connected intermediate its ends to one end of a two-armed bell-crank lever fulcrumed at its apex to a fixed pivot pin and connected at its opposite end to another snap-action spring. Adjacent said snap-action springs each of said support and lever carries a stud engaging a vertically elongated aperture formed in a loop formed in a corresponding jacquard cord. Each friction roller has on its outer periphery an annular tire of resilient soft material formed with transverse grooves and adapted to engage the cylinder surfaces.
