摘要：
The present invention relates to a rolling mill (1) comprising:
- a rolling stand (2) comprising at least two rolls (3) between which a strip (N) to be rolled is made to pass;
- at least one reel (4A, 4B) comprising a mandrel (10) for winding and/or unwinding said strip (N) during the rolling operations, wherein said mandrel (10) comprises a clamping system (20) associated with a slot (11) of the mandrel (10) for clamping one end of the strip (N) in said slot (11) during a step of winding the strip (N) on the mandrel (10).
The invention is characterized in that the clamping system (20) comprises at least one grip (20A) forming a clamp together with an inner wall (11A) of said slot (11), said at least one grip (20A) being coupled to a closed hydraulic circuit (21, 22, 23, 24) of the clamping system (20), which allows said at least one grip (20A) to translate relative to the wall (11A), so as to switch from a first open position, wherein the strip (N) can be inserted into said slot (11), to a second closed position, wherein the strip (N) can be clamped in said slot (11), and vice versa.
