装置。[Claims for Utility Model Registration] In a running shearing device that cuts a continuous long rod-shaped or linear workpiece into predetermined lengths while feeding it along its axial direction, a pair of rotating drums that are arranged facing each other in close proximity to each other and are driven to rotate in opposite directions with peripheral speeds matching the supply speed of the workpiece; and a pair of cutting blades disposed in L-shaped notches formed in opposite directions to each other, and the rotating drum has a semicircular cross section in the circumferential direction of the outer circumferential surface having a radius equal to or larger than the radius of the workpiece. A guide groove is formed therein, and the one cutting blade has an outer circumferential surface formed into a flat surface continuous to the circumferential surface of the rotary drum, and a semicircular groove continuous to the guide groove formed on the outer circumferential surface. The peripheral edge of the open end of the semicircular groove on the tip side of the drum is used as a cutting edge, and the other cutting blade has an outer circumferential surface formed into a curved surface protruding from the circumferential surface of the rotary drum, and the outer circumferential surface is provided with the guide groove. A rotary running shearing device characterized in that a series of semicircular grooves are formed, and a peripheral edge of an opening end of the semicircular groove on the tip side of the outer circumferential surface is used as a cutting edge.
