Assembly to wind-unwind thin slabs which cooperates with a continuous casting plant (11) producing thin slabs (12) and is positioned on the same axis as that plant (11), a heating and temperature-equalisation furnace (17) being included upstream of the winding-unwinding assembly (10), at least one pair of drawing rolls (23) cooperating with the winding-unwinding assembly (10), which comprises two coiling-uncoiling units (20a-20b) positioned circumferentially equidistant from, and on, a base plate (21) able to rotate about a substantially central vertical axis, one of the units (20a-20b) taking over alternately the position and function of the other unit (20a-20b) and viceversa, each coiling-uncoiling unit (20a-20b) being equipped with its own lead-in guide (26) and powered rolls (28), the powered rolls (28) being coplanar and positioned below the thin slab (12) and cooperating with a curvature-imparting roll (29), which can be moved from a position of cooperation with, and between the powered rolls (28) to an upper position when a coiled roll (33) has been fully coiled, the curvature-imparting roll (29) cooperating with actuator means (32) that adjust its pressure towards the powered rolls (28), the actuator means (32) being associated with arm means (30) that supports the curvature-imparting roll (29), the lead-in guide (26) lying on the same plane as the plane of feed of the thin slab (12) and as the upper side of the powered rolls (28). <IMAGE> |
