The invention relates to a bar screen device (1, 1', 1''), especially for treating fibrous suspensions in the paper industry. Said device comprises a plurality of bars (2, 2', 2", 2" ) which are fixed to at least one reinforci ng element (3, 3', 3", 3" ) in such a way that they extend parallel at a pre- determined mutual distance which is defined by spacer elements (4*, 4*', 4*" , 4*" ), the mutual distance between the same defining the width of the slits in the bar screen device. The spacer elements (4*, 4*', 4*", 4*" ) are also embodied as connecting elements (4, 4', 4", 4" ), especially in order to avo id notch-induced resistance variations, and fix the bars (2, 2', 2", 2" ) to th e reinforcing elements (3, 3', 3", 3" ) in such a way that they are distanced, in all three dimensions, in a positively and force locking manner, from the base of the bars to as close as possible to the neutral fibres of the bars ( 2, 2'; 2", 2" ) impinged upon. In this way, the bars can be fixed to the reinforcing elements without welding, and the separated, spatially positivel y locking connections between the bars (2, 2', 2", 2" ) and the combined space r and connecting elements (4*, 4*', 4*", 4*" ), and between the combined space r and connecting elements (4, 4', 4", 4" ) and the reinforcing elements (3, 3' , 3", 3"), are largely free of any notch effect, such that the component resistance remains unlimited.
