Abstract
In a station for forming stacks of layers of articles, a horizontal supporting surface has a window for allowing a layer to pass freely therethrough. First pushing bars drive the layers along the support surface. A stationary descending ramp starts from the initial part of the window and extends downstream. A horizontal lower surface is situated after the ramp and under a horizontal upper surface, and forms a part of the support surface situated downstream of the window. An additional conveyor is associated to the window to restore cyclically a continuity in the support surface in the region of the window for the odd layers, and consequently to direct each odd layer toward the upper surface, and to allow the even layers to pass cyclically through the window. The even layers are consequently directed, due to gravity, onto the ramp. Second pushing bars move each even layer to the ramp and convey the even layer to the lower surface. Third pushing bars move then each even layer on the lower surface, situated below. The even layer moves with the same speed as the corresponding odd layer, pulled by one of the first pushing bars on the upper surface.
