The invention provides a connector assembly for fastening filter elements onto a supporting plate of a press filter, comprising a first cylindrical core, a first flange extending outward from the first cylindrical core, a second cylindrical core, and a second flange extending outward from the second cylindrical core. The first cylindrical core is shaped and dimensioned such that it snugly passes through and is meshed with a central through hole of the supporting plate, and the second cylindrical core is shaped and dimensioned such that it snugly passes through and is meshed with the first cylindrical core. Both the first cylindrical core and the first flange and both the second cylindrical core and the second flange are respectively molded integrally from a non-woven fabric which has the ability of self-sustaining and shape maintenance, and is moldable. The invention also relates to a press filter fitted with the connector assembly.

A filling shoe including a circular slurry opening extending between a filter plate side and a filter chamber side. A flange surrounds the slurry opening, and has an annular groove surrounding it and being arranged for receiving a filter medium. An outer edge of the body has a bevel towards the filter plate side on at least a part of the filling shoe. An outer edge of the flange is also provided with a bevel. Particularly, the filling shoe is formed as a single uniform piece of elastomer. A pin hole is provided so as to extend through the flange a position corresponding to the annular groove. A filling shoe arrangement, a filter medium assembly and a method for providing a filter medium with a filling shoe are also disclosed.

Cloth retention apparatus for retaining the edges of a filter cloth comprises an edge strip having which can engage with a channel in a frame member, and be retained therein by a wedging member. The wedging member may be separate or attached to the bead, or incorporated therein.

An assembly comprising a filter plate for filter press and at least one attachment part, wherein the filter plate has a filter chamber boundary surface, by means of which a filter chamber to be formed in the filter press can be bounded. At least one channel for a fluidic connection to the filter chamber boundary surface is formed in the filter plate, and the attachment part is detachably fastened to the filter plate at the channel by means of at least one detachable ball-type snap-in connection. The ball-type snap-in connection comprises at least one ball pin and at least one coupling. An assembly comprising such a filter plate for a filter press and at least one attachment part, in which the attachment part is detachably fastened to the filter plate by means of at least one ball-type snap-in connection and has an opening which is arranged in the channel.
