Abstract
A method and apparatus for making bags or pouches is disclosed. It includes a track, at least two sleds that move on the track, and operating stations mounted on the sleds. The film moves along the track, and the sleds move with the film while performing operations on the film. The system can have the sleds stationary while operating for an intermittent machine, and move to reconfigure when the film is moving. The operating stations include one or more of a sealer, a heater, a cooler, an inserter, a knife, a punch, a perforator, a static charger, and a printer. The track forms a continuous path or is linear. A controller controls the sleds and operating stations. The controller includes an operating time and/or a reconfiguration module. The operating time module is responsive to a user set material thickness or a sensed material thickness.
