Abstract: A method and a machine for folding bags comprising a first conveyor for positioning a flat bag over a first support surface. A pair of sealer bars holds the bag stationary over the first support surface in predetermined alignment with a first folding device. The first folding device effects a first fold to the flat bag and a second conveyor positions the folded bag on a second stationary support surface. A second folding device effects a second fold to the folded bag, and a third conveyor positions the twice folded bag onto a third stationary support surface. A third folding device is provided for imparting a third fold to the twice folded bag, and it includes an orientation support frame to position the bag for transferring same to a collector trough. A predetermined quantity of bags are collected in the collector trough, and identified for transfer into a container.
