ABSTRACT:
The invention relates to a device for guiding a band-type product (1) especially a metal band, comprising at least two conical deflectors (2, 2′) arranged head to foot.According to the invention, each deflector (2, 2′) comprises a fixed base (3, 3′) whereon are mounted, in the manner of satellites, a plurality of rotating guiding rolls (4, 4′) forming the same angle (A) with an axis (30, 30′) of the deflector (2, 2′), and said deflectors (2, 2′) are oriented relative to the longitudinal running axis (10) of the band (1) so that the latter comprises successively, in the running direction, an upstream portion (1a) tangent and perpendicular to an input generatrix (5a) on a first deflector (2), a central portion (1b) tangent and perpendicular, upwardly to an output generatrix (5b) of the first deflector (2) and, downwardly, to an input generatrix (5′a) on the second deflector (2′) and a downstream portion (1c) tangent and perpendicular to an output generatrix (5′b) of the second deflector (2′).
