Abstract: An installation and a method for selectively producing a single-ply or alternatively a multi-ply nonwoven includes an inclined wire former configured to deposit a sheet of wet-laid fibre material on a first circulating belt, a further belt configured to receive the sheet of wet-laid fibre material from the first circulating belt, a roller card arranged downstream in the material transport direction and configured to introduce a roller card web into the installation, a hydroentanglement arranged downstream in the material transport direction and including at least one water beam configured to entangle, bond and/or structure a single sheet of fibres or a plurality of sheets of fibres, and a dryer arranged downstream in the material transport direction

Abstract: A building element for a toy building set comprising a plurality of such building elements, said building elements comprising a box-shaped body part having a surface with a top side and an underside, and a plurality of side faces extending downwards from the underside of the surface, a plurality of coupling flanges being arranged between the side faces, said coupling flanges extending downwards from the surface at a distance which is smaller than the distance at which the side faces extend from the surface, a plurality of coupling studs being arranged on the top side of the surface, each of said coupling studs having a top face positioned at a height above the top side of the surface which is greater than the difference between the distance at which the coupling flanges and the side faces extend from the surface, said coupling studs, coupling flanges and side faces being shaped such that the coupling studs of a building element engage, face-to-face, both the coupling flanges and the side faces of another buil
