Abstract
A bag-making and packaging machine including a bag-making apparatus 1, a bag-filling (packaging) apparatus 2, and a bag transfer apparatus. The bag-making apparatus 1 of a bag-making and packaging machine, while releasing a film F from a film roll disposed in the horizontal direction and feeding the film lengthwise, folds and overlaps the film in two in a horizontal attitude, performs sealing in locations corresponding to the bag bottom portions and side portions of the film in the horizontal attitude, and separates bags by cutting. The line corresponding to the bag bottom ends of the folded and overlapped film F (this position indicated by S) is set in the same position regardless of the bag length, and the respective apparatuses such as the forming apparatus 5, sealing apparatuses 8, 9 and 11, and cutting apparatus 14, etc. are disposed with reference to this position.
