Abstract: A supporting structure of plastic construction for a formwork panel, comprising a supporting structure and a formwork skin which is positioned on the front side of the supporting structure and attached to the supporting structure, wherein the supporting structure has two longitudinal edge supports and two transverse edge supports, characterized in that the supporting structure comprises a main body made of plastic, to which the two longitudinal edge supports and the two transverse edge supports belong, and, in the region of the front sides of the two longitudinal edge supports and/or of the two transverse edge supports, has an edge protection provided for protecting at least part of the edge of the formwork skin after attachment thereof to the supporting structure, wherein the edge protection is made of a material different from the material of said supports of the supporting structure and has a portion projecting forward from the respective said support; and/or in that the supporting structure has a main bod

Abstract: The present invention concerns a device for regulating the flow of a liquid used for the manufacture of ceramic products and which may be used in plants (2) with at least one elastically deformable pipe (3), for supplying/draining the liquid to/from a mould for the manufacture of the products; the device (1) comprises: an actuator (5), placed in contact with an outer surface (3a) of the pipe (3), to generate a controlled pressure (P5) on the outer surface (3a) of the portion of the pipe (3) with which it is in contact; fixed contrast elements (6) fitted to and acting on at least the outer surface (3b) of the pipe (3) opposite to the surface (3a) in contact with the actuator (5) and for a length (L6) comparable with the length (L5) in contact with the actuator (5), to enable the portion of the pipe (3), when the actuator (5) is activated, to be deformed in a controlled and uniform manner.
