(54) | Paper making machinery |
(57) A paper making machine includes a dryer section which constitutes 50% or more of
the length of.the paper machine. It has been proposed to reduce or obviate this dryer
section by subjecting the paper sheet simultaneously to high nip pressures and temperatures,
but conventional wet press felts are not suitable in a press drying system. The invention is concerned with an endless permeable belt for releasing moisture from fibrous paper making dispersions or sheets formed therefrom in which the belt is formed from a flexible corrosion and stretch resistant sheet having a high tensile strength and which is formed from metallic fibres laid randomly in a sheet and bonded together. Such a belt can be used in press drying or can also be used in other parts of the paper machine as well as the press drying section. |
