Abstract
A drawing frame for a spinning machine is provided with a blocking mechanism movable into a position between the upper and the lower feed rollers, in the event of yarn breakage, to lift the roving from contact with the driven roller. The blocking mechanism holds the roving. A roving holder is coupled to the means for actuating the blocking mechanism for synchronous operation and is provided downstream of the inlet roller. It comprises a table extending beneath the roving and a rotatable shaped arm above the roving which arm is movable by the switching mechanism to simultaneously hold the front end of the roving. The table is provided with a guide lug at its free end extending at an upward angle relative to the rotatable arm and the arm is covered with an inclined member having a slope running toward the guide lug. The sloping member and the guide lug are spaced from each other to define an opening which communicates with the space between the supporting table and the rotating arm to thereby automatically cause the roving, which, is laying on the rollers of the drawing frame, to slide into position on the table.
