摘要： A form-fill-seal machine is configured to adjust for changes in the thickness of bags within a short time, and is provided with seal jaws, gas removal members, an air cylinder, and a control unit. The seal jaws transverse-seal a cylindrical film in a widthwise direction forming a bag. The gas removal members come into contact against the bag prior to transverse sealing of an upper edge part, discharging a gas upward from the bag. The air cylinder moves the gas removal members, switching the position of the gas removal members between a first position and a second position with respect to the seal jaws. The control unit, in a time slot just prior to the start of a transverse sealing action performed by the seal jaws, changes the timing of switching between the first position and the second position, and adjusts the amount of gas discharged from the bag.

摘要： A bag making and packaging machine includes a cutter fixed to a sealing member that cuts a laterally sealed portion of a film using pressure force with which a pair of sealing members sandwiches the film during lateral sealing. The bag making and packaging machine further includes a pair of sealing jaws, a knife, a pressurization mechanism, and a pressurization mechanism control part. The knife fixed to one sealing jaw, fusion-cuts the laterally sealed portion of the film. The pressurization mechanism exerts pressure force on one sealing jaw towards the other sealing jaw so that the pair of sealing jaws sandwiches and laterally seals the film therebetween, and the knife comes into contact with a laterally sealed portion and fusion-cuts the laterally sealed portion. The pressurization mechanism control part causes the pressurization mechanism to cease exerting pressure force based on error information pertaining to the film or the goods.
