Abstract (en)

Universal rolling-mill of the type with rolling rollers on planetary system, involving four opposite planetary wheels (1,2,3,4), identical and symmetric, each comprising a solar wheel that bears satellites rolling-mill rollers (r), characterized in that: two planetary couples of opposite rolling are used which rotation axis lie on the same orthogonal plane as or substantially adjacent to the laminate to be reduced; said satellites rolling-mill rollers of each planetary system, are spaced out with a value such to allow the orthogonal rolling-mill interferance to not be in the same plane as satellites rolling-mill rollers of the other couple; a planetary couple is in staggered synchronism in the rotation for the rolling; in such a way that in a single rolling phase one has the rolling alternation of the respective satellites rolling-mill rollers of the opposite couples as in a gear, causing the laminate to undergo some progressive reductions of orthogonal section in an orthogonal way also alternating, during the contemporary, but staggered, rotation of said opposite planetary couples. <MATH>
