- a method for producing a bag in which a three-dimensional design is imparted to the laminated film 11 using a molding die using the bag making and packaging machine is as follows. First, the laminated film 11 is supplied to the bag making and packaging machine 20 while winding the laminated film 11 from a supply roll around which the laminated film 11 is wound. The laminated film 11 is conveyed by the pull-down belt 24c of the bag making and packaging machine 20 and heads toward the shoulder portion 23a of the former 23.
- the laminated sheet 11 is pasted on the inner surface of the laminated film 11 at a predetermined position at a predetermined interval by the reinforcing sheet pasting mechanism. .
- the reinforcing sheet 14 is not attached to the position where the vertical seal and the horizontal seal are performed in the subsequent process.
- the laminated film 11 is subsequently formed into a tubular shape in the process of being conveyed from the shoulder portion 23a of the former of the bag making and packaging machine 20 to the cylindrical portion 23b, and moves downward while moving along the former surface. Both ends of the film are overlapped in the running direction, and vertical sealing is performed by the vertical sealing mechanism 21.
- the vertical seal can be in the form of envelopes, joints V, or misalignment.
- Table 1 shows the flowchart when molding is performed using the molding die 26 (26A, 26B, 26C) shown in FIG. 5 in the apparatus shown in FIGS. 4A and 4B.
- the mold 26 provided in the former 23 is the male mold 26A
- the mold facing the mold 26A is the female mold 26B.
- the female die 26B has a built-in heater (not shown) for heating the laminated film 11, and a blower 26C for evacuating the molding die during molding and a female die toward the male die 26A.
- a moving mechanism (not shown) for moving forward and backward is provided.
- Laminated film 11 is A registration mark is detected by a sensor (not shown) in the process of being supplied to the machine 23, and the position of the laminated film 11 on which the three-dimensional design is to be formed is specified based on information from the sensor.
- the female mold 26B moves forward so that the three-dimensional design is formed at the specified position, and the operation of the vacuum blower 26C is started, whereby the inside of the mold 26 is evacuated and molded. After the three-dimensional design is formed, the operation of the blower 26C stops and the female die 26B moves backward.
- the lower end of the laminated film 11 is sealed at an appropriate interval by the horizontal sealing mechanism 22 to form an unfinished bag with the upper end of the laminated film 11 being opened, and the product C is a cylindrical tube with a form. It is fed into the unfinished bag through the inner cavity of part 23b. Finally, the upper end of the unfinished bag is sealed by the horizontal sealing mechanism 22 and cut into individual bags by the knife of the horizontal sealing mechanism 22 to give a three-dimensional decoration on the surface, and the item C is A sealed and filled bag 10 is produced.
- the force indicating the step of forming the three-dimensional design is the step of performing the vertical sealing before and after forming the three-dimensional design.
- the method of manufacturing the bag 10 having a three-dimensional design using the three-dimensional sheet 16 is slightly different from the method described above.
