Zusammenfassung:	CONTACT PLATE FOR HEAT-MASS EXCHANGE APPARATUS The present invention relates to contact plates for heat -mass exchange apparatus and may be used in various branches of industry and in production of polymeric materials. The plate has a base provided with at least one perforation widening in one direction, its edge with its widening end contacting the apparatus walls. With a plate having a plurality of perforations the edges of the perforations disposed along the periphery of the base contact the apparatus walls and the edges of adjacent perforations contact each other, thus reducing the development of stagnant zones on the plate, decreasing its hydraulic resistance and improving the efficiency of heat -mass exchange.
