Abstract (en)

A tension roller leveler which will produce neither abnormal noise nor flaws called chatter marks even in a high-speed treatment line. A plurality of work rolls (1,2) are disposed on each of an upper frame (7) and a lower frame (8). The upper frame and/or the lower frame can be regulated to adjust opening degrees of the work rolls in the inlet side and the outlet side for a strip (S). A plurality of the work rolls are each supported independently over substantially the entire length by one set of backup rolls (3,4) in two rows, and the backup rolls in two rows are arranged in a zig-zag pattern such that shaft support portions (5,6) of one set of the backup rolls in two rows will not overlap with each other.
