Abstract
A suction control apparatus is adapted to be used in a packaging machine for conveying and packaging a belt-shaped film while the film is being suctioned by a suction-type film conveyor. The suction control apparatus includes a proper vacuum-degree determination section and a vacuum-degree control unit. The proper vacuum-degree determination section is configured and arranged to determine a proper degree of vacuum of the suction-type film conveyor, which is less than a reference value set in advance. The vacuum-degree control unit is configured to set the degree of vacuum to a first value corresponding to the proper degree of vacuum determined by the proper vacuum-degree determination section.
