Abstract
A rolling apparatus is disclosed which forms a thin walled portion on part of a steel strip by allowing the steel strip to intervene between a pair of upper and lower rolling rolls, in which the upper rolling roll is vertically movable. The steel strip which has been pressed between a pair of upper and lower rolling rolls is repeatedly moved on a traveling table to upstream side and downstream side alternately, thereby forming the thin walled portion having a width corresponding to the movement quantity. In forming the thin walled portion, the steel strip is grasped on both upstream side and downstream side with a plurality of clamping means and is subjected to a tension due to tension imparting means, thereby facilitating formation of the thin walled portion.
