ABSTRACT:
Improved means are provided in a loom dobby for taking-up play in the control unit. The surfaces of the fixed and mobile blades which limit the stroke of the rocker arms in this unit are positioned perpendicular to the line joining the points of contact between the dobby hooks and knives to the mean points of contact between said blades and the rocker arms. Moreover, said surfaces are concave in the fixed blades and convex in the mobile blades. The linkage which cause the mobile knives to oscillate are in the form of false articulated parallelograms.
