Abstract

ABSTRACT
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 are disposed on each of an upper frame and a lower frame. 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. A
plurality of the work rolls are each supported indepen-dently over substantially the entire length by one set of backup rolls in two rows, and the backup rolls in two rows are arranged in a zig-zag pattern such that shaft support portions of one set of the backup rolls in two rows will not overlap with each other.
