Method for pressing creases into metal panels with a main initial crease to grip the panel followed by secondary pressing of other creases

摘要

A method for pressing a pattern of several creases into a metal panel (1) presses an initial main crease (2) by virtue of the shape of the press halves, followed by a secondary press process in which separate press heads inside the main press form apply the secondary creases (3, 4) while the panel is securely held without lateral displacement.
