ABSTRACT:
An inlet table for a restrained mandrel mill includes a plurality of roll units arranged in the pass line direction and the roll units are mechanically swung in synchronism with the forward and backward movements of a mandrel bar, thereby supporting the mandrel bar and/or a shell to be rolled on the pass line and preventing the roll units from striking against a restrained bar for moving the mandrel bar.
