A carton bottom end tucker-tacker assembly for folding over, closing and tacking the bottom ends of a pair of cartons mounted on a pair of mandrels at a tucker-tacker station on a carton packaging machine. The tucker-tacker apparatus includes a tucker apparatus for engaging a pair of opposed triangular bottom end closure members on the bottom ends of each of a pair of stationary cartons and breaking the bottom end closure members and folding them inwardly toward a closed position, after which the tucker apparatus recedes and a pair of swingably mounted tucker and tacker jaws then move under the partially closed bottom end members of each of the pair of cartons and complete the folding and tucking operations, and concluding with a tacking in place of the bottom end closure tuck-over panel on each carton to retain the bottom end closure members in a square condition for subsequent transferral to a carton bottom end pressure sealing station. The tucker jaws and the tacker jaws are each water cooled, and they are adapted to be operated by the same power drive means as used to operate the tucker apparatus. The tucker-tacker apparatus comprises a pair of swingably mounted tucker wings, for each of said pair of cartons, which swing inwardly and outwardly in planes transverse to the direction of movement of the pair of cartons in and out of the tucker-tacker station. The tucker and tacker jaws of each pair of said jaws are pivotally mounted on an axis that is disposed transverse to the direction of movement of a pair of cartons in and out of the tucker-tacker station. |
