Abstract
An apparatus for manufacturing a trapezoidal wire using two-set shaping rollers has a body rotating about a central axis at a predetermined speed, a plurality of first shaping roller sets installed along an outer circumference of the body, each first shaping roller set including an upper roller and a lower roller and a shaping portion, into which a wire is inserted to be processed, between the upper roller and the lower roller, and a plurality of second shaping roller sets arranged after the first shaping roller sets along the outer circumference of the body and in a direction in which the wire moves, each second shaping roller set comprising an upper roller and a lower roller and a shaping portion, into which the wire is inserted to be processed again, between the upper roller and the lower roller, wherein wires processed by the first and second shaping roller sets while passing therethrough are stranded by the rotating body. The apparatus can significantly improve a wire processing rate while reducing a defect rate.
