摘要:
A machine for cleaning textile fibres including a casing, a horizontal opening roller rotatably mounded in the casing, the roller body having a roller body and beater rods protruding from the peripheral area of the roller body and bar grates arranged below the underside of the opening roller. Textile fibres in the form of flocks are conveyed in a delivery air stream through an inlet which is arranged at a first end of the opening roller. An outlet for egress of the delivery air stream is arranged at the other end of the opening roller. In one arrangement, the radial length of the beater rods decreases from the inlet to the outlet and the diameter of the roller body increases from the inlet to the outlet. This arrangement allows the opening of the fibre flocks to be improved and permits a more complete separation of impurities through the bar grates.
