Abstract
A fiber cleaning machine has a horizontal roller (1) fitted with beater rods (4, 5). Bar grates (4, 5) are arranged under the lower side of the roller. Over the upper side of the roller (1), an inlet (9) opens out at one end of the roller (1), and an outlet (10) opens out at the other end for a current of delivery air for transporting the fibers in flock form. Between the inlet (9) and the outlet (10), sheet metal deflectors (11) are arranged obliquely over the upper side the roller (1) to provide transfer chambers which move the current of delivery air in the direction of the axis of the roller (1). Cooperating with the transfer chambers is a partition (30) which is permeable to air and dust and which is a wall of a low-pressure chamber (20). Not only can coarser impurities be separated through the bar grates (4, 5), but also finely divided impurities may pass through the permeable partition (30) into the low-pressure chamber (20) where they are sucked into a suction pipe (15).
