ABSTRACT:
A method and apparatus for unclosing and enclosing the flaps of a package carton, so that cartons can be transported along the transportation path without shifting backward or shifting away from the transportation path. The method consists of (a) disposing a package carton on a first transportation slab with the opening of the package carton facing downward; (b) continuously guiding the package carton in the longitudinal direction of the first transportation slab; (c) folding the leading first flap in an upward and forward direction, and guiding the leading first flap to lap on a second transportation slab, then urging the lagging first flap to lap on the second transportation slab; (d) folding the second pair of flaps to trap the second transportation slab between the opening of the package carton and the second pair of flaps; (e) guiding the second pair of flaps to skip from underneath the second transportation slab and to lap on a third transportation slab; (f) folding the leading first slap in a downward and backward direction to trap the third transportation slab between the opening of the package carton and the leading first flap, and guiding the leading first flap to lap on a fourth transportation slab; (g) folding the lagging first flap in a downward and forward direction to trap the fourth transportation slab between the opening of the package carton and the lagging first flap; and (h) guiding the lagging first flap to lap on a fifth transportation slab.
