Abstract:
1. A guiding system of a metal strip exiting from a rolling mill, defining a longitudinal feeding direction, comprising: at least one roller table, comprising a plurality of feeding rollers having at least in a central part thereof, in cross section to the feeding direction, a curvilinear profile, wherein there are provided at least one lead-in and containment means of the strip, arranged on said at least one roller table and provided with a blowing system of a fluid which is suitable to issue jets of fluid onto the moving strip in order to deform the strip on said feeding rollers so that the strip displays, in cross section with respect to the feeding direction, a profile corresponding to that of said feeding rollers, wherein there are provided guiding tables, arranged between the feeding rollers of at least one roller table, in order to support a head of the strip, wherein in order of said feeding direction, one or more pinch rolls, adapted to drag the head of the strip along said feeding direction are disposed prior to said at least one roller table, and wherein one of said pinch rolls comprises a pair of stiffening rollers for stiffening the strip, where the lower roller has, in cross section to the feeding direction, a profile corresponding to that of at least the central part of the feeding rollers, said stiffening rollers being suitable to deform the strip so that it displays, in cross section to the feeding direction, the aforesaid curvilinear profile, and wherein along a cross direction with respect to the feeding direction, an upper surface of the guiding tables has a curvilinear profile, at least in a central part thereof, conjugated to the profile of the feeding rollers in order to further minimize instabilities upon the passage of the strip head on said feeding rollers.
