Abstract: A pulper for comminuting and suspending fibrous material includes a container and at least one rotor arranged in the container for circulating a fibrous material suspension located on the container and at least one rigid sieve. The rotor at least predominantly passes over the sieve surface which is provided with round sieve openings. As high a throughput as possible and as low an energy consumption as possible are to be achieved by limiting the cross-section of the sieve openings exclusively defined by circle segments.

Abstract: Process for manufacturing screens and screens suitable for use in wet screening fibrous paper suspensions, in which the screens include at least one screen plate having a number of sorting apertures. The process includes providing a number of fastening openings in the at least one screen plate, and inserting profiled pieces into the fastening openings. At least a portion of the profiled pieces are arranged to project beyond a screen surface.

Abstract: The invention is directed to arrangement wherein an object is scanned by a columnar light spot traveling in a first coordinate direction (x). The light scattered or transmitted from the object is directed to a linear detector whose individual, sequentially scanned elements effect the resolution of the object in the second coordinate direction (y). The object is scanned via a first layer of mutually adjacent light-conductive fibers which are placed directly on the object. A second layer of fibers overlaps the first layer in crosswise fashion and directs the scattered light toward the detector. In the region where the fiber layers overlap, the cores of the fibers are exposed on the side thereof facing the object and are covered with diffraction gratings to couple the light into and out of the fiber cores.
