Abstract:
A device for creasing paper, comprising:a first drum with an axis and having an outer surface comprising around circumferences of the surface one or more first grooves of a first width and a first depth; a second drum with an axis and having an outer surface comprising around circumferences of the surface, one or more receiving grooves of a width greater than the first width; and one or more first resilient creasing rings for location in the grooves of the first drum to project radially outwards from the outer surface of the first drum to a first height; such that, when the first and second drums are located adjacent to one another, with their axes parallel, first resilient creasing rings projecting from the first drum can lie within the receiving grooves of the second drum to form creases in a sheet of paper fed between the first and second drums.
