Abstract: A bagmaking and packaging device includes a transverse sealing unit, a first tube member, and a gas flow path member. The first tube member is disposed above the transverse sealing unit and extends in an up and down direction. The first tube member allows a packaging material to become wrapped around it to thereby form the packaging material into a tubular shape. At least part of the gas flow path member is disposed inside the first tube member. The gas flow path member delivers nitrogen into the packaging material formed into the tubular shape. The first tube member includes a cutout portion that extends in the up and down direction. The cutout portion is formed so that the nitrogen can move between a space between the packaging material formed into the tubular shape and the first tube member and the inside space of the first tube member.

Abstract: A bagmaking and packaging machine forms a packaging material in a tubular shape and packages packaging articles. The bagmaking and packaging machine includes a former, a wraparound member, and a support member. The former folds and guides the packaging material. Around the wraparound member is wrapped the packaging material folded by the former. The support member supports the former and the wraparound member. The former includes a collar member that guides the packaging material and a first tube member for forming in a tubular shape the packaging material guided by the collar member. The first tube member has one end to which the collar member is connected, and includes a first mating portion that is mated with the support member.
