The lid of the edge is a basic cover will die out of roll edge into a circular shape. Now usually has three kinds: one kind is the punch mould pressure out of the circular arc edge is to have a dedicated to the edge of the punch or pressure on the same press have two step mode, the first step in blanking, the second step blank-holder. This form is more complex, investment is large, but the edge size is stable, the cover image quality is higher. The second form is similar to roll in the form of sealing machine, formed by pressure roller modeling and the lid to roll edge. This form because of its complex structure, adjustment difficulties, has been gradually abandoned by people. The third form is the most widely used simple: the crimping machine is mainly consists of rotating disc, outer mould and plate. External formwork generally have 5 ~ 8 pieces of installation on the base can be adjusted and in turn into mould of the distribution of involute. When the cover into the crimping machine rotates along the outer mold due to the rotating disk drive after rolling, turning this mode has a circular arc shaped groove. Because the outer mold and rotation plate spacing gradually decreases, and deformation of compression mold cover GouYan inside and outside circular trough realization of edge. Plate in the process of the role is to ensure that the cover edge is not downward bending deformation.
