Abstract
A web is folded upon itself and transversely sealed. The web is cut into individual pouches which are fed into gripper units, on an endless conveyor, each having a fixed leading jaw and a movable trailing jaw which grip the leading and trailing edges of the pouches. To open a pouch, the trailing jaw is moved toward the fixed jaw by a cam and held in position by friction. Each opened pouch is carried around a filler unit where it is filled. Thereafter, a cam causes said jaws to spread apart, stretching the mouth of the pouch, where it is sealed in a heat sealer.
