Abstract: In a rotating filter a filter cloth (18) is arranged outside a filter skeleton (34, 36). The filter cloth is provided with at least one bending resistant element (37, 38) extending through a pocket (49) arranged in or on the filter cloth (18) to restrain bulging of the filter cloth due to forces perpendicular to the plane of the filter cloth. The filter sector skeleton (34, 35, 36, 45) is provided with radially outer support and guide means (43, 44) and radially inner support and guide means (45, 46). The bending resistant element (37, 38) is at its ends adapted for detachable engagement with said means such that the ends are undisplaceable perpendicularly to the support and guide means (43, 44, 45, 46). Preferably, at least one end of the bending resistant element is displaceable in the circumferential direction of the filter sector.
