Abstract

Drawing frame for drawing fiber sliver with draw frame rollers comprising a pair of pre-drawing rollers and a main drawing roller pair. Power transmission members in the form of flat belts are used for driving the draw frame rollers. A deflection pulley engages the flat belts between respective pairs of wheels deflecting the belts for increasing the angle that the flat belt extends around the respective wheels to provide a non-slip engagement between the flat belts and the respective wheels.
