Abstract
A machine for cleaning textile fibres including a casing, a horizontal opening roller rotatably mounted in the casing, the roller being fitted with beater elements and at least one group of grate bars arranged below the underside and approximately parallel to the opening roller. Textile fibres in the form of flocks are fed to the opening roller in a current of delivery air through an inlet located above and at one end of the opening roller. An outlet for removing the delivery air is arranged above and at the other end of the opening roller. A clearance between the grate bars and the opening roller is adjustable. Therewith, the machine can be optimally suited to the type of textile fibre material to be cleaned. The grate bars can also be further adjustable on a axis parallel to their own longitudinal axis, so that the setting angle of the grate bars, with reference to the current of delivery air, can also be adapted to the type of the textile fibre material.
