Method for producing a rotationally symmetrical screening device with a plurality of profile bars and screen basket for a pressurizable screen. The method includes producing bent bar holders having a radius of curvature of smaller than a radius of curvature of a finished screening device and having cut-outs open at an edge of an exterior circumference of the bent bar holders. The method also includes inserting profile bars parallel to one another into the cut-outs, and forming rings from the bar holders with inserted profile bars by enlarging the radius of curvature of the bar holders, thereby narrowing the cut-outs and clamping the profile bars. The forming of rings includes transferring bending forces to at least two locations on sides of the bar holders not provided with the cut-outs. The method also includes fixedly connecting respective ends of the bar holders to one another.
