Abstract

In order to extend the roll nip pressure zone in the press section 1 of a paper machine it is proposed that an auxiliary strip 12, which has an elastically compressible hollow layer that will return to its original shape again, be applied between the press felt 4 and a press element 3. The hollow layer is composed of one or more elastic fabric layers 16, 17, which form a woven structure, on both sides of which there is a surface layer 15, 19, which retains liquid in the hollow layer. An auxiliary strip may contain multiple hollow layers, and where the surface layer is composed of impermeable material the hollow layers may be filled with various suitable liquids for regulating the elastic characteristics. Where an elastic fabric layer 16, 17, with a surface layer of gauze 19 is used in the layers nearest the web in order to produce a hollow structure, the auxiliary strip beyond the roll nip extension can also be used in order to remove greater quantities of water from the press or as so-called bulking felt. <IMAGE>
