ABSTRACT:
The bag top folder and labeler includes bottom and side conveyor assemblies for conveying a filled bag to extend between a pair of folder subassemblies wherein, with the bag top extending above the subassemblies, a second subassembly is operable to in cooperation with a first subassembly reversely fold the bag top relative to the second subassembly center folder and flap tuckers to form a generally Z-shaped bag top closure including ears extending outwardly in opposite directions and elevator mechanism for elevating the bag relative to the first subassembly to compensate for different densities of product in filled bags. Thereafter labeler mechanism applies labels to the folded bag top including to the ears, folds the ears downwardly along the end walls and wipes the labels to adhere to the ears and the bag front and rear end walls below the ears.
