PROBLEM TO BE SOLVED: To provide a bag-making apparatus which can prevent an article from being caught in a seal part.SOLUTION: In a bag-making apparatus, a bag body 100A, of which an upper part is opened and a lower part is sealed, is filled with an article. Then, pressing members 72, 72 press a predetermined range including a range of the bag body 100A filled with the article from both sides to start degassing of the bag body 100A. Then, the bag body 100A is sealed laterally at an upper part than the predetermined range. The bag-making apparatus includes: restriction members 61, 61 which are arranged between a lateral seal part which is sealed laterally and the pressing member 72, and are oppositely arranged on both sides of the bag body 100A; and restriction member moving means 62, 62 of moving the restriction members 61, 61 toward the bag body 100A to a predetermined position where a mutual distance of the restriction members 61, 61 becomes a distance at which the article in the bag body 100A is not passed upward and air in the bag body 100A can be discharged upward. The restriction member moving means 62, 62 move the restriction members 61, 61 to the predetermined position in starting the degassing.SELECTED DRAWING: Figure 3 |
