Abstract:
A filter sector for a filter disk of a rotating filter, said filter disk comprising a plurality of such filter sectors, said filter sector including two inter-connected plate-shaped elements (2,3) formed from a sheet material and each plate shaped-element having planar portions defining a main plane (13) protrusions (14) shaped in the material of the plate-shaped elements extending outwardly from the respective main plane and being adapted to keep a filter cloth at a distance from the respective main plane, characterized inthat mutually spaced, substantially parallel ridges (15) are shaped in the material of the plate-shaped elements and continuously extend in a first direction over the filter sector,that said protrusions (14) discontinuously extend over the filter sector in a second direction substantially perpendicular to said first direction, each protrusion lengthwise spanning over at least two adjacent ridges (15), and laterally adjacent protrusions (14) being lengthwise displaced in relation to each other by at least a spacing between adjacent ridges (15),that said ridges (15) have a height above the main plane (13) less than said distance, andthat the main planes of the plate-shaped elements are adjoined.
