Self-Exposure Shutter Rolling Conditions
The reliability of the «breathing» shutter depends both on its geometric parameters and on the rolling conditions. When the tin cover is rolled in by a seaming roller, the rubber ring is compressed, which can be considered as a preliminary tightening of the check valve spring. In canneries, rollers of various profiles are used to break in the SKO tin cover. This paper presents a study of the conditions for rolling a self-exhausting shutter with rollers of characteristic profiles common in factories.
