ABSTRACT:
A method of providing net bags with wicketing flaps at their mouth ends. A series of net bags are fed forward in a path with the bags extending transversely of the path and spaced longitudinally with their mouth ends aligned. As the bags are fed forward, a tape is secured to one wall of the mouth ends of the bags, extending from bag-to-bag and projecting beyond the mouth edge of the bag wall to a free edge spaced outwardly of the mouth edge of the bags. The tape is severed between the bags to provide a flap, the flap being adapted to receive a wicket for holding a plurality of the bags in stacked assembly.
