Abstract
A method and apparatus for packaging powder material includes feeding a continuous web of V-shaped heat sealable material to a first forming station to form longitudinally spaced upright seals to provide longitudinally spaced upwardly opening pouches. The pouches are filled with powder material at a filling station and then pulled through a downwardly curving path while the bottoms of the pouches are supported. The upper portions of the pouches are heated along the downwardly curving path and then snapped shut and pressed together to form a top seal with a set of nip rollers positioned at a lower portion of the downwardly curving path. Sealed pouches are then severed from the continuous web to form separate packages.
