Abstract: An object of the present invention is to provide a control method for a box motion type end-sealing carried out by a longitudinal type or lateral type bag forming, filling and packaging machine, which can permit the end sealing time period to be set as long as possible even if a linear section (a sealing length of a predetermined stroke) is made constant. There is provided a method of controlling an end-sealing time period for a bag forming, filling and packaging machine.

Abstract: An automatic packaging system comprising a container fabricating mechanism for forming a tubular structure from laminated paper capable of heat sealing, marking folding guidelines for forming rectangular-prism-shaped containers, cutting individual pouched containers from the tubular structure, and shaping one end of each pouched container, and a packaging mechanism for filling the shaped containers with a filling material and sealing the openings of the containers. The container fabricating mechanism includes a rotating mandrel mechanism formed of a plurality of radially arranged pairs of forming plates to receive the cut pouched containers.
