Abstract
A pouch machine continuously forms a series of multi-pitch, multi-product pouches in a continuous web of pouch material by folding the web and then forming spaced side seals to define a pouch closed on three sides with an initially unsealed mouth on top. The pouch is opened to its maximum volume prior to filling by pressurizing the pouch. Pressurization is achieved by introducing a curtain of compressed air under a plate and passing the mouths of the pouches adjacent the plate and thus through the air curtain. First and second plates engage the front and back panels of the pouches to assure correct pressurization of the pouches.
