Abstract:
1. A method of reducing thickness of unbroken rolling stock ( 14 ) by longitudinal rolling, comprising the steps of providing a plurality of rolls ( 22 to 25 ; 82 to 84 ) having sidewise offset deformation regions ( 26 to 28 ; 86 to 88 ) and arranging the plurality of rolls ( 22 to 25 ; 82 to 84 ) one after another in a rolling stock displacement direction (W); and deforming the rolling stock ( 14 ) in a width direction thereof with the sidewise offset deformation regions ( 26 to 29 ; 86 to 88 ) of the plurality of following one another, in the rolling stock displacement direction (W), rolls ( 22 to 25 ; 82 to 84 ), with the sidewise offset deformation regions of the rolls ( 22 to 25 ; 82 to 84 ) penetrating in the rolling stock to a same depth, whereby thickness of the rolling stock ( 14 ) is reduced.
