A vertical bag-manufacturing and packaging machine includes a feeding unit having an upstream tube portion, an opening/closing mechanism, and a downstream tube portion. The upstream tube portion is configured and arranged to downwardly convey the article. The opening/closing mechanism is disposed on a downstream side of the upstream tube portion with a gap being formed between a downstream end of the upstream tube portion and an upstream end of the opening/closing mechanism, and configured and arranged to selectively open or close to selectively discharge or hold the article discharged by the upstream tube portion. The downstream tube portion is disposed on a downstream side of the opening/closing mechanism, and configured and arranged to downwardly convey the article discharged by the opening/closing mechanism, the downstream tube portion having an internal diameter that is larger than an internal diameter of the upstream tube portion. |
