Abstract: A trimming device for metallic sheets including: an upper knife, comprising a central circular face having a diameter D1 and a thickness T1, mounted on an upper shaft, a lower knife, comprising a central circular face having a diameter D2 and a thickness T2, mounted on a lower shaft, wherein said upper knife and said lower knife are vertically shifted with an overlap (DOVERLAP) so as to define a shear of said metallic sheet and wherein at least one of said upper or lower shaft is able to be moved vertically, a first distance sensor, able to measure a vertical distance to the upper end of said upper knife, a second distance sensor, able to measure a vertical distance to the lower end of said lower knife, a computer able to compute the overlap.

Abstract: A continuous caster to cast a metal product has a plurality of upper and lower segment frames bearing rolls, the upper and lower segment frames being located respectively above and below the cast metal product. At least one bending measurer is located on at least one of the upper segment frames and able to emit a bending measurement signal indicative of a bending of the at least one of the upper segment frames. A processor is disposed to receive the bending measurement signal and to calculate a location Pmes of the crater end based on the measured bending signal, the crater end location being the location
