いない。[Problems to be Solved by the Invention] In the automatic packaging method of the above-mentioned conventional techniques (!41), a strip-shaped film is fed out from the original film to a folder via an intermediate roller, and a cylindrical package is made with the folder. Therefore, no technology has been disclosed regarding adjusting the film tension of the strip-shaped film.Therefore, if the strip-shaped film stretches and sag between this tape sealing device and the film base, the welding position of the opening tape may vary. This causes the problem that the tear tape is not placed at the desired position during packaging formation.Sagging of the strip film occurs when the film tension of the sealing film is low, and when the film tension is too high, the film does not stretch. This may deform and cause wrinkles.For this reason, it is necessary to maintain the film tension within a predetermined range, but as mentioned above, no prior art has disclosed any technology that focuses on this point.

The purpose of the present invention is to provide a method for adjusting film tension.

法である。In the present invention, tear tape is intermittently welded at predetermined positions on a continuous film strip, and the film is shaped into a cylinder, filled with contents, and sealed to create a package with tear tape attached. In the continuous bag making and packaging method, the film tension of the band-shaped film is measured between a sealing device that welds the original film of the band-shaped film and the opening tape, and a brake is applied to the unrolling shaft of the original film based on the measured tension value. This is a continuous bag making and packaging method in which the film tension of the film (i) is maintained within a predetermined range by adjusting the amount.

給装置９からの供給物が収納される。The drawing is a front view showing the overall structure of a continuous bag-forming and packaging machine used in the method of the present invention. In this packaging machine, a strip-shaped film 4 is unwound from an original film 5 (vinylidene chloride resin), passes through the rollers of a tension detection device 2, passes through a nip roller 3 and a group of rollers 6, and is delivered to a tear-tape sealing device 7.
and is sent to folder 8. The folder 8 is a cylindrical package containing the strip film 4. The supply from the supply supply device 9 is housed within the package.

以前の位置で、かつフィルム張力の測定が高積度に行わ
れる位置としてこの間が最も適切であるためである。Since the nip roller 3 is configured to be fed at a circumferential speed that is substantially the same as the feeding speed of the strip-shaped film 4, the speed of the 4jF-shaped film 4 between the original film 5 and the nip roller 3 is substantially constant. A brake amount adjusting device I is engaged with the film roll 5, and a feed-out shaft 13 of the film roll 5 is engaged with the brake amount adjusting device I.
Adjust the brake force applied to the brake. The tension detection device 2 measures the film tension between the film original 5 and the nip roller 3, and is configured to detect the film tension using a detection means such as a strange gauge that engages with its rotating shaft. The detection value of the tension detection device 2 is sent as a signal to the brake amount adjustment device 1, and the brake amount adjustment device 1 adjusts the brake force of the feeding shaft 13 based on this. If the braking force of the feeding shaft 13 increases, the film tension between the film roll 5 and the nip roll 3 will increase, and if this is decreased, the film tension will decrease. The tension detecting device 2 is placed in the illustrated position because this is the most appropriate position before it comes into contact with the sealing tape sealing device 7 and where the film tension is measured at a high density.

、シワの原因になり易い。It has been found in experimental civil engineering that the film tension is desirably in the range of 25 g to 50 g per width (cm) of the film 4. If it is less than 25 g, the strip film 4 tends to sag, and if it is more than 50 g, the strip film 4 tends to stretch and wrinkle.

ない値である。In any case, in the conventional method that does not employ a tension detection/adjustment device, the position of the opening tape of the package obtained during continuous bag making gradually shifts from the [14. However, according to this embodiment, the positional deviation of the l;il sealing tape position is large (
It has been demonstrated that both can be kept within 6 mm. This value is a value that does not pose a problem as a product of a package with a tear tape attached to the package.
