Abstract: The method envisages that groups of articles (2,22) to be packaged, arranged orderly with a lateral narrowed dimension oriented in the forward movement direction (A), are fed along a feeding line (1). Single packaging sheets (3) are carried beside the feeding line (1), in suitable phase relation with the forward movement of the articles (2,22). The groups of articles (2,22) are transferred crosswise to the feeding line (1), so as to hit the sheets (3) with the lateral narrow extension of the groups of articles (2,22) in order to fold the sheets (3). The folded edges of the sheets (3) are joined along the opposite side of the groups of articles (2,22), presenting a corresponding lateral narrow extension.

Abstract: According to a method for packaging one stack of multiply articles made of paper, a presser receives and compacts the stack of articles to be packaged and a pusher moves longitudinally the stack so as to make the stack hit a wrapping foil, previously placed vertically. The stack, partially wrapped within the wrapping foil, is introduced between a pair of belt conveyors. The presser and the pusher are carried by a slide moving longitudinally between a backward position with respect to the wrapping foil, where the stack is received and compacted, and a forward position, in which the presser hit the wrapping foil and move close to the belt conveyors, so as to transfer and introduce the stack between the belt conveyors.

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.
