APPARATUS FOR MANUFACTURING CYLINDRICAL FILM-FORMED BODY, AUTOMATIC FILLING AND PACKAGING MACHINE FOR CYLINDRICAL PACKAGED BODY, AND INTERNAL HEATER

摘要

PROBLEM TO BE SOLVED: To provide an apparatus or the like capable of easily manufacturing a cylindrical film-formed body and a cylindrical packaged body having excellent seal strength and excellent appearance.

SOLUTION: The apparatus for manufacturing the cylindrical film-formed body includes a cylinder manufacturing means for forming a cylindrical body in which a strip-like synthetic resin-made film is curved in a cylindrical shape, and both side edges of the synthetic resin-made film overlap each other, and a hot air sealing means for forming the cylindrical film-formed body by blowing hot air to an overlapped portion of the cylindrical body and executing the heat-bonding of the overlapped portion. A hot air applying nozzle for blowing hot air from an outer circumferential surface side of the cylindrical body to the overlapped portion, and an internal heater for applying the heat from an inner circumferential surface side of the cylindrical body to the overlapped portion are used in the apparatus.
