Abstract
1344348 Paper-making FELDMUHLE ANLAGEN-UND PRODUCTIONS GmbH 16 June 1971 [16 June 1970 28 May 1971 (2)] 28203/71 Heading D2A A dewatering unit of a paper-making machine comprises a plurality of sub-units disposed in contiguous side-by-side relationship across the width of the machine wire, the sub-units comprising carriers 6, 7 on which are mounted bar segments 12 of a wear-resistant sintered hard material, preferably having a hardness of 7 Mohs, e.g. aluminium oxide. The wire-contacting surfaces of the segments 12 are substantially coplanar, and the unit may be subject to a vacuum. The segments are secured by bolts 14 which pass through slots 11 permitting longitudinal adjustment of the segments, the bolts engaging with spiral springs disposed in tappings 13. In a second embodiment, Fig. 3 (not shown), the segments are secured to the carriers by notched pins driven into the carriers and extending into the segments where they are fixed by a twocomponent adhesive based on an epoxy resin. The segments may also be secured to the carrier by an adhesive. In a third embodiment, Fig. 4 (not shown), the carriers are bolts passing through the segments which have bushes extending beyond the sides of the segments for receiving the bolts and spacing the segments along the bolts. The segments may be secured to the bushes by an adhesive, and distance pieces may be disposed between adjacent bushes. Adhesive joints may be coated in acid-proof chlorinated rubber.
