Method and related equipment for the production of filtering panels (8) made up of a filtering fabric (5) locked and tensioned inside a frame (7) consisting of two mutually coupled half frames (7a, 7b), wherein the moulding of said frame (7) of said panel (8), the unwinding of said fabric (5) from a feeding roller (4) and the tensioning of the same fabric (5) in the frame (7) are carried out, the latter being performed automatically during said moulding step. Compared to the solutions employed in the prior art, the equipment and the method of the invention offer the advantage of automating every operation for assembling the filtering panel, locking the fabric in a centered position on the frame in the making, tensioning it and cutting it out around the frame already moulded on the panel.
An equipment for the production of filtering panels (8) made up of a filtering fabric (5) locked and tensioned inside a frame (7) consisting of two mutually coupled half frames (7a,7b), said equipment including a press (6) and a mould half (2) movable with respect to a fixed mould half (3), characterized in that said moving mould half (2) is provided with a mould insert (9) sliding between a first position, for moulding the half frame (7a) of the panel (8), and a second position, for moulding the second half frame (7b) of the same panel (8) on said half frame (7a).
