Title: Paper coating blade - has less bending resistance at end zones to reduce roller wear
Inventor: MADRZAK ZYGMUNT
IPC: D21H23/34
Filed: 1991-06-15
Abstract: The scraper blade for paper or cardboard coating, at a roller, has a structured bending resistance at the end zones where the roller is not covered by the paper web, which is less than in the centre section. Or the bending resistance, constant over the web width, decreases at a steady and/or a slight shift to the end sections of the blade. Pref. at the changing zone for the bending resistance, the decrease towards the ends of the blade is continuous or abrupt through rows of weak points, parallel to the longitudinal edges of the blade, such as openings or slits or notches and nicks, equidistant within the rows. The weakened points in each row are displaced from those in neighbouring rows, or they can be in an increasing number towards the narrow end sides of the blade, or the interval between weakened points can increasingly become smaller towards the ends of the blade. The line defining the end of the weakened zone can be a continuous logarithmic curve or segment of a parabola or hyperbola originating near a longitudinal edge and a narrow side of the blade. The opening width has a dia. of 0.3-8.0mm or a slit width of 0.3-2.5 mm. Triangular holes can be used, with a tongue pressed out from it at an angle of max. 30 deg. to the blade. Parallel slits/notches/nicks can be pitched at an angle of 30-45 deg. to the longitudinal edges of the blade, using uninterrupted slits/cuts. The opening interval (c) in a row is smaller than the division there. The edge zones of the scraper blade can also be thinner than in the remainder of the body, or of a different material which bends more readily. The scraper blade works with a roller with a metal core and a rubber mantle with a max. hardness of 80 Pu.J. ADVANTAGE - The blade structure reduces wear on the roller through a worn blade.

Inventor: SERRE YVES
IPC: F16C17/04
Filed: 1991-07-13
Abstract: A curved semicircular bushing (2) that forms the bearing surface of an axial plain bearing is outwardly enlarged at its apex area and narrows down to its base line, forming an angle of approximately 45 DEG . In addition, the semicircular bushing (2) has at its ends lateral enlargements (8) that extend in a prefered embodiment up to the outer radius of the vertex of the bushing.
