Abstract 1,074,759. Textile treating apparatus. H. FLEISSNER H. FLEISSNER and G. FLEISSNER, [trading as ANSTALT FUER PATENTDIENST], Oct. 22, 1965 [Nov. 21, 1964; April 13, 1965], No. 44747/65. Heading D1L. A device for the wet treatment of fibrous or granular material comprises a container 11 filled with treatment liquid, at least one sieve drum 1 subjected to suction such that liquid flows from outside into the drum interior forcing the material against the drum and penetrating the material, a baffle plate 2 in the drum arranged so as to interrupt the suction at one portion of the drum and consisting of flat sheets arranged immediately below the liquid level, the exhaust or suction openings being arranged considerably below the liquid level. Sealing strips 3 are provided between the baffle 2 and the drum 1 and the baffle may be combined with the suction device as on the left of Fig. 1 or there may be a separate suction tube 10 as shown on the right of Fig. 1. In an embodiment having several sieve drums (Fig. 2, not shown) the drums are spaced apart and the material is conveyed between them on a conveyor belt (12) and whilst on the belt can be rinsed by liquid from boxes (16), the liquid being pumped from the sieve dums via lines (15). The amount of liquid passing into boxes (16) is controlled by a flap or other similar device. In a further embodiment (Figs. 5-7, not shown) is the liquid container (11) has a sieve bottom (20) so as to provide a settling box (27) therebeneath, a worm conveyor (30) being provided to remove the deposited contaminations. The supporting surface of the conveyor belt is preferably arranged below the liquid level by the thickness of the material layer and suction boxes (34) may be arranged below the upper run of the belt.
