ABSTRACT:
A yarn cutting scissors device suitable for use for cutting a weft is disclosed which is capable of decreasing the frictional force occurring between a stationary blade and a movable blade when both blades are successively engaged in the cutting operation and effectively accomplishing the accessible engagement between both blades. The yarn cutting scissors device includes a leaf spring which has one end fixedly mounted on a support block and the other end on which a stationary blade is mounted, a shim washer arranged between the support block and the leaf spring, and a compression coil spring mounted on the support block to constantly urge a movable blade against the stationary blade, so that the stationary blade may be oscillated in the direction perpendicular to that of oscillation of the movable blade.
