Abstract of the Disclosure A process for manufacturing a slotted hole screen is suggested, wherein the slotted screen is particularly suited for use in devices for the sorting or cleaning treamtment of aqueous fiber suspensions, for example in paper manufacturing. In the process, cross bars are attached onto wire- or bar-shaped longitudinal members defining the screen slots. In order to substantially reduce the danger of the catching and thus the flocking and/or web formation of fibers in the suspension on the slotted hole screen during the subsequent operation of the screen, the joints between the longitudinal members and the cross bars are provided with coverings having a smooth surface out of a solder or another smoothly flowing, solidifying material on their exposed surfaces.
