Abstract

The apparatus comprises a continuous path, divided into a first rising section and a second substantially horizontal section, having a conveyor extending there along and carrying one or more pushers adapted to withdraw individually folded and flattened cartons from a container magazine provided and arranged at the top of the rising section. At the junction location between the two sections, movable supports are provided which receive, when at a first position arranged in continuation of the rising section, individually folded and flattened cartons and transfers the latter, when arranged at a second position in which said supports are arranged parallel to the conveying along the substantially horizontal section, again on the conveyor without said cartons being left by the one or more pushers. This assures a correct arrangement of said cartons on said conveyor downstream of the junction location.
