Abstract: A screening device (e.g., screen plate or screen cylinder) is manufactured relatively inexpensively and easily yet has uniform screening openings (e.g., screening slots) even when of a width of less than 0.5 mm. A plurality of wires having first and second sections (the second sections having base portions and of smaller cross-section than the first sections) are mounted substantially parallel to each other, supported by at least one support bar or ring. The bars or rings have slots formed in a first side surface, and a cavity in open communication with the slots in a second side surface. The wires are fixed to the bars or rings by deforming the wires (e.g., by bending a flap, engagement by a reciprocating tool, welding, etc.) within the cavity, or by deformation of the support bar or ring in the cavity. The screen plate or cylinder is preferably used to screen or otherwise treat a cellulose pulp suspension, e.g.

Abstract: A screen, such as a drum screen or a flat screen, for screening or fractionizing pulp suspensions or the like suspensions of the pulp and paper industry. The screen comprises a reinforcement attached to the surface of the screen plate, such as a reinforcing ring (16, 18) attached to the surface of a drum screen (10). The reinforcement (17) is made of fiber-reinforced composite material. The invention also relates to a method of manufacturing the reinforcement of a screen plate of composite material. The composite material is preferably made of reinforcing fiber and plastic matrix material.
