  • Publication number: 20130299113
    Abstract: A headbox is provided that comprises at least one first inlet channel adapted to receive furnish comprising fibres, at least one turbulence generator connected to the first inlet channel, a second inlet channel adapted to receive a non-fibrous high consistency composition, and a sliced cone connected to the turbulence generator and the second inlet channel. The first inlet channel and the turbulence generator are arranged so that the furnish is passed through the first inlet channel and further to the turbulence generator and thereafter to the sliced cone. The second inlet channel is arranged so that the non-fibrous high consistency composition is passed through the second inlet channel and directly to the sliced cone bypassing the turbulence generator.
