Abstract
A bed plate (13) for a fluidized bed apparatus is made from a plate (23) from sheet metal and comprises openings (22) for fluidizing air or gas of the so-called "gill-type". In order to reduce or prevent fall-through of product, at least one of the edge portions (24,34) defining the opening (22) has been deformed so as to increase the extension thereof along the plane of the bed plate, and so as to thereby reduce or eliminate the orthographic projection on said plane of the opening (22). Such deformation may comprise compression and/or stretching. The edge portion or portions (24,34) are preferably deformed to such an extent that a partial overlap is obtained.
