ABSTRACT:
A method of supplying cartons to a carton-packaging machine, comprising the steps of providing flattened cartons stacked in a line in a container package so that two cutouts on the cartons are lined to form two grooves on two parallel sides of the cartons; inserting two bar-shaped forks into the grooves respectively in the stacking direction of the cartons; pressing the cartons to be together along the inserting direction of the bar-shaped forks by pressers, which are adjustable for a different stacking amount of the cartons, so that the cartons are placed at the central portion of the bar-shaped forks; pulling out the cartons from the package with the bar-shaped forks; and supplying the cartons to the carton-packaging machine with the bar-shaped forks.
