Unveiling the Key Technical Points of Arc‑Roll Leveling: Jinlun Roller Industry Shares Practical Reference Standards for Substrate Wrinkle Removal.

Jiangsu Jinlun Roller Industry has publicly released practical guidelines for achieving optimal flattening with spreader rollers. To attain the desired stretching and wrinkle‑removal results, ensure that the material’s travel direction is perpendicular to the unfolding direction, and align the material’s centerline with the centerline of the curved roller’s surface.

Jiangsu Jinlun Roller Industry has publicly shared practical guidelines for achieving optimal flattening with spreader rollers. To attain ideal stretch‑and‑wrinkle‑removal results, ensure that the material’s travel direction is perpendicular to the unfolding direction and that the material’s centerline aligns with the centerline of the spreader roller’s surface. At the same time, select an appropriate wrap angle and carefully control the spacing between the spreader roller and the upstream and downstream guide rollers. Industry recommendations suggest setting the arc height to 0.6%–0.9% of the roller width, while also taking into account factors such as the smoothness of the roller’s curvature, rotational flexibility, surface runout, and resonance suppression. Only through the coordinated optimization of multiple parameters can defects like “figure‑eight” wrinkles and mid‑section edge slack be effectively eliminated.
