  • Patent number: 8635969
    Abstract: A device for guiding a strip through a liquid contained in a tank, includes an immersed diverting roller, in particular a roller immersed in a bath of liquid metal such as zinc, mounted rotatably about an axis on two aligned supporting shafts extending through two respective side walls of the tank, and each rotating in a centering bearing positioned outside of the tank. Each bearing of one shaft of the roller includes two rotary supporting members mounted in a fixed housing and spaced apart from each other, namely an outer supporting member and an inner supporting member. The housing of the bearing is held against a support plane formed on the wall and perpendicular to the axis of a hole through which the shaft passes. The wall has measures for centering the housing on the axis.

  • Patent number: 5152333
    Abstract: The roll comprises a core (6) and a sleeve (7) in which latter are provided ducts (8) for the circulation of a cooling fluid. According to the invention, the sleeve (7) is rigidly connected to the core (6) in its axially median part and substantially throughout its circumference by an assembly which prevents any axial and radial displacement in this median part of the sleeve relative to the core, such as a dovetail assembly (9, 10) or a T-way assembly. The sleeve is in contact with the core throughout its width and is maintained by its edges (7', 7") on the core by maintaining means (11, 12, 13, 14) which allow an axial displacement but prevent a radial displacement of the edges of the sleeve relative to the core.
