Abstract
Abstract An apparatus for continuously forming containers, filling the containers with material and packing the containers containing material includes a heating device for heating a bottom sheet of thermoplastic resin supplied intermittently thereto, a forming device for forming container portions from the heated bottom sheet while keeping the latter continuous, a filling device for filling said container portions with material, a sealing device for sealingly covering the container portions with a cover sheet bearing pitch marks corresponding to symbol marks printed thereon, a punching device for removing the sealed containers from the continuous bottom material sheet, and is characterized by that a mark reading device is disposed at a position separated from the sealing device by a distance equal to a distance between the forming device and the sealing device, that a device is associated with at least one of the sealing device and the punching device for forwardly or reversely moving at least one of the sealing device and the punching device in the direction of the bottom sheet supply and that another mark reading device including a pair of mark detectors is provided for reading marks each within one pitch of the cover sheet.
