Most of the existing methods for rolling pattern processing of the cap are to support it from the inside and then add rolling patterns to it. When the force for supporting the inside of the cap is relatively large, it is easy to cause the cap to deform, resulting in the scrapping of the cap, thus reducing the production rate and affecting the economic benefits.
