Abstract
In a horizontal form-fill-and-seal (FFS) machine, a continuous length of packaging film is folded lengthwise over the consumer products to be packaged. The lateral edges of the packaging film are separately and independently aligned with one another by edge sensing and control devices. A zipper is fed between the aligned lateral edges of the packaging film. The lateral edges are sealed to one another, and the zipper sealed to the folded packaging film, by a pair of sealing sections, each of which includes a pair of parallel sealing devices. Side seals are produced by conventional means, which also separate completed packages from one another.
