For both economical and technical reasons, the widths of the paper machine have reached their limit which can be estimated at 11 meters. Contrary to this, the speeds of the paper machine keep rising,: the machines run faster and faster, and no one can predict where it will stop. This significant increase of the paper machines performances is indeed linked to the improvements achieved by the paper machine builders; each of the main components of the production tool is at the center of more and more sophisticated research. This is how the Allimand Company, after having developed a large range of new products such as the S hydraulic headbox with control profile by dilution, the E former, the A.Sizer, the soft calander or the G reel, has just launched on to the market it's new Naos shoe press. This shoe press has been validated on a brand new pilot plant installed in Allimand's workshops, in Rives. Designed for linear pressures up to 1400 kN/m, the Naos shoe press can be integrated into various sorts of press sections and used for as many different grades of papers as printing writing, Iwc, newsprint or linerboard. The goal of this document is to explain the design of the Naos shoe press and to highlight the key-parts of an equipment the papermakers should derive maximum benefit from.
