摘要

PPROBLEM TO BE SOLVED: To prevent any trouble attributable to burrs formed on an edge of a core piece part when a space part is formed in a core embedded in a weather strip. PSOLUTION: A plurality of space parts 24 are formed by the punching at predetermined intervals in the longitudinal direction of a core material, and a core 16 having the shape with a core piece part 22 and a space part 24 being alternately provided in the longitudinal direction is fed to straightening rollers 38. The straightening rollers 38 are rotated and the core 16 is held between the straightening rollers 38 and continuously moved in the longitudinal direction while being pressed. Straightening for executing the plastic deformation of burrs 26 projected in the thickness direction along an edge of the core piece part 22 to the inward of the space part 24 when forming the space part 24 is achieved to prevent the burrs 26 from being projected from the surface of the core 16. In this condition, the core 16 is held between the straightening rollers 38 while the core is curved in the longitudinal direction so that the burrs 26 are on the outer circumferential side, and the burrs 26 are effectively deformed to the inward of the space part 24.

要解决的问题：当在密封条中嵌入的型芯中形成空间部分时，防止由于型芯部分边缘上形成的毛刺引起的任何麻烦。

解决方案：通过在芯材的纵向上以预定间隔冲压而形成多个空间部24，并且具有交替地设置有芯件部22和空间部24的形状的芯16。在纵向方向上，矫直辊38被送入矫直辊38。矫直辊38旋转，并且芯16被保持在矫直辊38之间，并在被按压的同时沿纵向连续移动。为了防止毛刺26从表面突出，实现了矫直，该毛刺用于在壁厚部24的厚度方向上沿着芯片部22的边缘向空间部24的内侧突出的毛刺26的塑性变形。在这种状态下，在芯子沿纵向弯曲的同时，芯子16被保持在矫直辊38之间，使得毛刺26位于外周侧，并且毛刺26有效地向内变形。空间部分24的
