APPARATUS AND METHOD FOR CLOSING RECLOSABLE BAGS ABSTRACT OF THE DISCLOSURE A machine automatically applies a tin tie strip across the top of bags in a predetermined series of steps wherein the bag top is closed downwardly twice in a double fold after the tin tie strip is affixed to one of the bag side walls. Glue applied to the exposed, outside surface of the first fold holds the bag top closed in the double fold condition. Bendable lengths of the tin tie strip projecting from the leading and trailing edges of the bag side wall are sequentially bent around the bag top through full 180° turns into snug engagement with the other bag side wall as bays are moved through the machine by conveyor means. ¦
