PROBLEM TO BE SOLVED: To reduce a quantity of films to be disposed of in a bag-making and packaging machine.SOLUTION: A bag-making and packaging machine 100 includes a carrier mechanism 10, a roll holding part 20, a printing mechanism 30, a former 60, a vertical seal mechanism 70, a lateral seal mechanism 75, a cutting mechanism 80, a first sensor 91, and a second sensor 92. The printing mechanism 30 prints information in a film F. The former 60 superposes two vertical lines of the film F. The vertical seal mechanism 70 makes a film cylinder FT by fastening the two vertical lines. The lateral seal mechanism 75 makes a lateral seal portion by sandwiching and fastening the film cylinder FT. The cutting mechanism 80 cuts the film cylinder FT in the lateral seal portion. The first sensor 91 detects a mark of the film F in order to specify a cutting position to be cut of the film cylinder FT. The second sensor 92 detects a mark in order to specify a printing position in which prescribed information of the film F is printed.SELECTED DRAWING: Figure 1 |
