A machine is disclosed for securing a closure system onto a discrete pouch. The machine includes first, second and third stations. The first station is capable of advancing discrete pouches and lifting and folding a portion of a first major surface of each pouch upon itself to form a lip, and exposing an inner surface of a second major surface. The second station is capable of positioning and attaching a closure system transversely across the exposed inner surface. The closure system includes a track having first and second legs each having an outer surface. The first and second legs are joined together by an opening/closing mechanism which includes a movable member capable of being moved back and forth. The third station is located downstream from the second station and is capable of unfolding the lip and securing opposite ends of the lip to the outer surface of the second leg.
