Abstract
A bag making machine automatically cuts off and seals plastic from a web of film in register with regularly spaced eyemarks. A correction system is disclosed for use when the film gets out of register with the eyemarks. When the correction system is activated, the film is advanced to the next eyemark. The bag making machine resumes normal in-register operation without ever shutting off the machine. A method of correcting lengths of bags being formed from a web of material is further disclosed.
