Claims

[Scope of utility model registration request]

A core metal of an edge decoration material that is integrally embedded inside a resin molded body extruded from a mouthpiece set in a die of an extrusion molding machine and is bent into a substantially U-shape by bending. comprises a large number of core tubes arranged in rows perpendicular to the longitudinal direction thereof, a first connecting piece repeatedly formed to alternately and integrally connect every other adjacent core tube, and the first connecting piece. and second connecting pieces that are repeatedly formed to alternately and integrally connect adjacent core tubes, and in the center of the second connecting piece, there is a connecting piece that connects the core tubes to each other. A core bar for edge decoration material, characterized by forming a narrow part that can be easily pulled and torn off when biasing pressure is applied in the direction of opening and separating the core bar.
