Abstract
A draw frame for spinning machine is provided with a blocking mechanism movable into a position between the upper and lower feed rollers in the event of yarn breakage, to lift the roving from contact with the driven rollers. The blocking member is mounted on a rail, extending parallel to a load arm on which the upper rollers are mounted. Both load arm and the bearing arm rail are swivelably mounted. Each of the bearing rails are arranged so that they are weighted by the supporting arm, when placed in the operating position, by a resilient member acting on a connecting member between the bearing rails.
