Abstract

PURPOSE:To decrease the fishtail amount formed at the leading end part of plate materials by taper-forming the trailing end part of a preceding plate material and the leading end part of the succeeding plate material simultaneously then subjecting the plate materials to broadside rolling. CONSTITUTION:The trailing end of a preceding plate material 3 and the leading end of a succeeding plate material 1 are simultaneously pressed by one operation of a pair of pressing tools 8, 8', whereby they are formed to a taper shape. At this time, stopper devices 12 are provided so as to prevent the preceding material 3 from being pushed forward, whereby the stopping accuracy of the plate material 3 is enhanced. The plate material 4 having been pressed at the leading end part is sent to next V-mills 6, whereby it is subjected to predetermined broadside rolling. With this method, the fishtail amount formed in the broadside rolling becomes small and the yield of broadside rolling is improved.
