Spout sealing method and sealing apparatus

A spout sealing apparatus comprising:

• a spout insertion and temporary-sealing apparatus in which:
• a plurality of spout holding members that hold spouts are disposed on a circumference of a continuously rotating rotor,
• insertion means that fit bags over said spouts that are held by said spout holding members are disposed so as to correspond to said respective spout holding members, and
• a temporary-sealing apparatus is disposed near said rotor so as to temporarily seal said bags and said spouts held by said spout holding members;
• a spout main-sealing apparatus in which:
• a plurality of spout holding members tat hold spouts are disposed on a circumference of a continuously rotating rotor, and
• main-sealing means that perform a main sealing of said bags with attached spouts that are held by said spout holding members are disposed so as to correspond to respective said spout holding members, and
• a rotating transfer apparatus in which a plurality of spout holding members that hold spouts are disposed on a circumference of a continuously rotating rotor, and wherein
• said rotating transfer apparatus is disposed between said spout insertion and temporary-sealing apparatus and the spout main-sealing apparatus, so that said rotating transfer apparatus continuously transfers bags with attached spouts from said spout insertion and temporary-sealing apparatus to said spout main-sealing apparatus.
