Filter comprising a continuous belt, and a filtering cloth supported by the belt, wherein the belt is a composite belt (1) which comprises a band (26) of rigid material which is made flexible by a profile of waves which are transversal or skewed to the direction of displacement (F), and at least two support belts (27, 28, 29) of elastic material, said support belts having a width which is substantially smaller than that of the profiled band sliding on stationary supports (30-33) during the displacement and being capable of cooperating with the profiled band (26) so as to mechanically drive the latter. |
