徴とするクロス圧延装置。 A pair of upper and lower rolls in which roll sectors that share the rolling process of the wire material to be rolled and roll relief parts that allow movement of the wire material are formed alternately on the circumference, and a longitudinal direction of the wire material. and a wire guide device for feeding in the direction and reciprocating in the width direction, and rotates both rolls in opposite directions so that the upper and lower roll sectors face each other on a line connecting their centers. At the same time, the wire material guide device is reciprocated in synchronization with the operation of this roll sector, so that the wire material is moved across the line connecting the centers and stretched in the width direction between both roll sectors. In a cross-rolling machine that rolls and returns it to its original position in the width direction and moves it in the longitudinal direction between the relief parts of both rolls, the shape of the roll sector is changed from the radius of curvature of the end of rolling to the radius of curvature of the beginning of rolling. A cross rolling device characterized in that it is formed to be smaller than the radius.
