<p>The invention relates to a device for guiding a ribbon (1) through a liquid (M) contained in a trough (11), comprising an immersed deflector roller (2) mounted rotatably about an axis (20) on two aligned supporting shafts (3) extending through the two respective side walls (14) of the trough (11), and each rotating in a centring bearing (4) positioned outside of the trough (11). According to the invention, each bearing (4) of one shaft (3) of the roller (2) comprises two rotary supporting members (42, 42') mounted in a fixed housing (5) and spaced apart from each other, namely an outer supporting member (42) and an inner supporting member (42'), the housing (5) of the bearing (4) being held against a supporting plane (P) formed on the wall (14) and perpendicular to the axis (10) of the orifice (15) through which the shaft (3) passes, said wall (14) having means (61) for centring the housing (5) on said axis (10). The invention applies especially to a roller immersed in a bath of liquid metal such as zinc.</p> |
