Abstract: A press for steeping cellulosic pulp in the manufacture of viscose comprises a tank 1 having an opening 7 in its bottom of size such that the whole charge of pulp can fall through it after steeping and pressing when the pressing member (not shown) is retracted, and a container 8 which can be positioned below the opening and sealed in liquid-tight relation to the tank, a shutter member 13 housed within the container, movable between a raised position in which it is capable of closing or substantially filling the opening (Fig. 1) and a depressed position in which it lies in the container (Fig. 2), below the level of the bottom of the tank, and having a degree of resiliently restrained movement in a substantially vertical direction when in its raised position. The shutter member may as shown be arranged to float into its raised position when caustic soda solution is supplied to the container.  Alternatively mechanical means may be provided for moving the shutter between its raised and lowered positions.  Thus resilient means (e.g. springs) or inflatable means may be used for urging the shutter towards its raised position and a lever system <PICT:0926785/IV(a)/1> <PICT:0926785/IV(a)/2> for depressing it.  The container may be resiliently mounted below the tank so as to move in a substantially vertical direction, its sealing means being such as to maintain liquid tight relation with the tank during such movement.  Thus an inflatable member (e.g. duplex seal 12) may be engaged between the container and the tank which on inflation will provide a liquid tight seal between them.  Inflatable shutter moving means and said inflatable member may be interconnected for simultaneous inflation.  The container may be mounted on wheels 9 for facilitating its movement between its operative position below the tank and its discharge position in which it is drawn to one side to permit the pulp to be discharged through the opening.
