The unloading device for filter press has upper means for supporting a series of filtering cloths which are associated with the opposite front surfaces of a corresponding series of plates arranged in a pack, the plates being compressible between a fixed head and a movable head, whereby to form a succession of filtration chambers into which the liquid to be filtered is fed. The supporting means are vertically movable between a raised filtration position, in which the filtering cloths are stretched, and a lowered unloading position, wherein an upper portion of the cloths forms a fold which is able to facilitate the separation of the bricks formed by the solid filtration residues. The unloading position corresponds to a limited opening of the filtration chambers.
