ABSTRACT:
A coarse cleaning machine for textile fibres including a casing, a horizontal roller rotatably mounted in the casing, the roller being fitted with beater elements and bar grates are arranged on the underside of the roller. Located above and at one end of the roller is an inlet which carries delivery air for conveying the textile fibres in the form of flocks and an outlet is located above and at the other end for the roller. Deflectors which are inclined with respect to the roller axis are arranged above the upper side of the roller between the inlet and the outlet. The deflectors define transfer chambers which deflect the delivery air further in the direction of the axis of the roller. At least part of the transfer chambers are covered by a wall which is permeable to air and dust and a low pressure chamber connected to a suction pipe is located above the wall. The machine can not only separate the coarser impurities through the bar gates but can also suck out the fine dust-like impurities through the wall which is permeable to air and dust, the impurities being sucked into the low pressure chamber and then into the suction pipe.
