ABSTRACT:
A rolling stand with tie-rods, having extremely high strength to axial stresses, which includes a stand base supporting at least two rolling rolls supported by carriers which can be vertically moved in order to be approached or moved away from each other by means of four vertical tie-rods having screw-threaded portions. The screw-threaded portions are provided on opposite sides of at least one pair of support feet arranged between the stand base and the carriers which support and contain a central smooth portion of the tie-rods. A contoured portion extends from at least one of the support feet upwards and downwards in a parallel direction to the tie-rods. The contoured portion houses and guides a vertical rib protruding outwards from the carriers. Both contoured portion and the vertical rib engage, on mutually opposite surfaces, freely removable adjustment/sliding elements.
