Abstract: A device for removing the gaseous laminar boundary layer from at least one of the two sides of a material web moved in transport direction preferably at high speed, for example said web being made of paper, characterized by at least one corona-charging electrode provided with at least one elongate tip, and connectable to a positive (+U) or negative high-voltage source, and characterized by at least one counterelectrode associated with the latter and connectable to a negative (−U) or positive high voltage or ground, with corona-charging electrode on the side of material web having the boundary layer to be removed, and the associated counterelectrode being located on the other side.

Abstract: A device for stacking objects, such as newspapers, magazines, or other stackable paper objects, on a transport table for further conveyance to another processing station, whereby the device includes a blocking device with at least one blocking device on each side of the stack and at least one charging device upstream of the blocking device for charging each object before it is stacked.

Abstract: The invention concerns a device for forming, on a conveyor table (7), a stack (6) of stacked objects, such as, for example, newspapers, magazines or the like, which stack is to be conveyed in the conveying direction. The stack is to be conveyed in the conveying direction. The stack is conveyed to a further, different workstation, for example, whilst being conveyed from a cross boom to a shrink-wrapping unit. The invention is characterized in that the stack has a blocking arrangement which comprises at least one charging electrode (11, 12) disposed in the conveying direction on both sides adjacent the stack and at least one contact roller (16) above the stack.
