Also in the bag making line, a sealing failure may occur. For this reason, a defective product is generated even in a bag-making line in which the articles to be packaged are properly supplied, and loss of the articles to be packaged properly is generated.

As a result, it is possible to increase the operating rate of the apparatus while suppressing the occurrence rate of defective packaging.

Since it is a bag making and packaging device that has a plurality of bag making lines and laterally seals on a tubular film, the bag and the tubular film are separated with a cutter, thus improving the operating rate while eliminating defective seals.
