Claims (10)

A deflector roll for changing the threading direction of a metal strip being threaded,
The deflector roll comprises a roll body rotatably supported on a roll base, and a slide member provided movably with respect to the outer surface of the roll body,
A deflector roll, wherein the slide member is configured to be movable along the axial direction of the roll body while the metal strip is wound around the slide member while maintaining the wound state. The slide member includes a plurality of plate-like bodies, and each plate-like body has its longitudinal end faces located on the roll end face side of the roll body and its width direction end faces facing each other. 2. The deflector roll according to claim 1, wherein the deflector roll is arranged along the entire circumference of the roll body. 2. The deflector roll according to claim 1, wherein each of the plate-like bodies has an arcuate surface forming a circular winding circumferential surface in an arrangement state over the entire circumference of the roll body. 4. A deflector roll according to claim 2 or 3, wherein each plate-like body is capable of moving individually along the axial direction of said roll body. 4. A deflector roll according to claim 2 or 3, characterized in that each plate-like body has a cross-sectional profile in which the longitudinal central portion protrudes outwardly beyond its opposite ends. The roll pedestal is provided facing the longitudinal end surface of the plate-like body in a region other than the region where the metal strip is wound around the roll body, and is arranged in the longitudinal direction of the plate-like body in a moving state. 4. The centering guide according to claim 2 or 3 , which is brought into contact with the end surface of the metal strip to return the plate-shaped body to its original position and center each plate-shaped body on the center of the threading of the metal strip. deflector roll. The centering guide comprises a base held by the roll mount and a guide plate cantilevered on the base,
The guide plate has a guide surface whose free end is the farthest from the roll end face of the roll body and whose distance from the roll end face of the roll body gradually decreases toward the fixed end. A deflector roll as described in Item 6. 3. The roll frame according to claim 1 , wherein the roll mount has guide rollers positioned at both ends of the metal strip in the width direction to prevent roll-out of the metal strip while the metal strip is being passed. deflector roll. The slide member has an elastic member that elastically supports the slide member so as to be movable along the axial direction of the roll body and returns the slide member to its original position by its urging force. A deflector roll according to Item 1. At least one deflector roll according to claim 1 or 2 is installed in a looper device, and a metal strip that has undergone an upstream manufacturing process is passed through the looper device and conveyed to a downstream manufacturing process. A steel plate manufacturing method for manufacturing a steel plate,
While passing through the looper device, the sliding member of the deflector roll is moved along the axial direction of the roll body together with the metal strip wound around the deflector roll by the frictional force resulting from the meandering of the metal strip. A method for manufacturing a steel plate using a deflector roll, characterized in that
