The apparatus includes a longitudinal jointing device (13) for overlappingly joining side edges of a belt-shaped film (F) to form a cylindrical film (F1) and a pressing device (40) in the longitudinal direction of the tubular film. The content-less portion of the content is formed flat at a predetermined interval; the portion overlapping with the cylindrical film filled with the content (C) is stored on the sheet The tape overlapping device (50) overlaps the tape (51) covering the overlapping portion of the content-free portion in the direction intersecting the longitudinal direction, and the lateral bonding device (61) welds the tape to the tubular film. And a primary seal cross-section of the aforementioned content-free portion is performed. Summarizing the Claims 1. A package manufacturing apparatus comprising: a vertical bonding device for overlappingly joining side edges of a strip-shaped film to form a cylindrical film; and a pressing device for longitudinally extending the cylindrical film. The content-free portion is formed flat at predetermined intervals so that the above-mentioned overlapped portions are accommodated on one side with respect to the cylindrical film filled with the contents; and the tape overlapping device is along the aforementioned length on the content-free portion. The tapes overlap each other in the intersecting direction. In the lateral welding apparatus, the tape is welded to the tubular film and a primary seal is performed across the content-free part.
