Process for rolling open profiles made of metal strips comprises initially rolling the deformed profile in the longitudinal direction after the first process step

摘要

After the first process step the deformed profile (1) is initially rolled in the longitudinal direction and in the base section (2) and in the side sections (3) up to the neutral fiber (4) of the profile cross-section, and then the second process step is carried out. Process for rolling open profiles made of metal strips comprises deforming metal strips in a first process step using a roller to produce an actual profile mold, especially having a base section and side sections, and bending in a second process about a bending axis directed across the profile axis and parallel to the bending axis. After the first process step the deformed profile (1) is initially rolled in the longitudinal direction and in the base section (2) and in the side sections (3) up to the neutral fiber (4) of the profile cross-section, and then the second process step is carried out.
