Abstract
A spout sealing method and apparatus using a spout insertion and temporary-sealing apparatus, a primary sealing apparatus, a secondary sealing apparatus and a cold-sealing apparatus that are installed in a row; and transfer apparatuses being installed between these sealing apparatuses. Each apparatus has a continuously rotating rotor. A plurality of spout holding members which hold and convey spouts are disposed at equal intervals on the circumferences of the rotors, and spouts are continuously transferred between the spout holding members of adjacent rotors. In the spout insertion and temporary-sealing apparatus, bags and spouts are supplied from different sources; and the bags are fitted over the spouts held by the spout holding members, and the bags and spouts are temporarily sealed by a temporary-sealing apparatus. Then, main sealing is performed by the primary sealing apparatus and secondary sealing apparatus, and the main sealing area is cooled by the cold-sealing apparatus.
