摘要: A method and apparatus for registration of a seal perforation on plastic bag include drum forming continuous film with respect to mark the perforator/cutting station location seal. This is used in making machine produce bags different lengths. detector locates printed diameter may be adjusted form at desired mark. detecting controller adjusts speed properly locate maintain skirt length.
