Two bagmaking and packaging machines are installed side-by-side. Each of the bagmaking and packaging machines includes a film supply unit in the rear portion, a former mechanism in the front portion, and a transverse sealing mechanism that transversely seals a top and a bottom of the film in the tubular shape into which a product supplied from a combination weighing apparatus is fed. Each of the bagmaking and packaging machines is disposed under a discharge chute of a corresponding combination weighing machine, which includes two combination weighing machines joined to each other substantially symmetrically in the left and right direction as viewed from above and a base member that supports the combination weighing machines. A maximum width of the bagmaking and packaging apparatus when viewed from the front is narrower than a width of the base member.
