ABSTRACT:
A longitudinal sealer for a bag maker-packaging machine is controlled such that when an abnormal condition is detected and the operation of the machine is stopped temporarily and then restarted after the abnormal condition is removed, the mechanism for moving the film and the heater for heating edge parts of the film to seal them together are deactivated and reactivated, but not both at the same time. Deactivation of the heater is delayed after that of the mechanism for moving the fill and/or reactivation of the movement of the film is delayed after that of the heater such that the film is certain to be longitudinally well sealed in spite of the interruption of the sealing operation.
