PCT No. PCT/AT93/00083 Sec. 371 Date Mar. 20, 1995 Sec. 102(e) Date Mar. 20, 1995 PCT Filed May 14, 1993 PCT Pub. No. WO93/23239 PCT Pub. Date Nov. 25, 1993The invention relates to an apparatus for separating liquid from solids-liquid mixtures, in particular fibrous matter suspensions, more particularly under pressure, comprising a solid retention component having liquid passages, composed of a screen and a supporting body for the screen. The invention is primarily characterized in that the solids retention component is designed in multiple layers, that layer which faces the solids-liquid mixture taking the form of a screen (3) with apertures (7) and that layer which faces away from the solids-liquid mixture being designed as a support body (4) having slot-shaped apertures (5). The invention furthermore relates to an apparatus according to the present invention in the form of a worm press.
