ABSTRACT:
A vat paper machine is disclosed, the machine including a cylinder-vat unit having a rotatable cylinder mold, a vat and a headbox for providing a continuous supply of stock to the vat. The vat has a special wall structure and is arranged upstream of the cylinder mold in such a manner that the wire gauze covered cylinder mold is brought into contact with stock in the vat to form a web by draining water from the stock through the wire gauze covered surface of the mold. An outer wire is also provided which runs in a loop over a breast roll, through the vat at the wall structure thereof and then over and around a portion of the circumference of the cylinder mold. The wall structure comprises an endless liquid-impervious belt forming an endless loop located on the inner side of the loop defined by the outer wire. The belt and the outer wire run together in close surface contact with each other at least within the area between the breast roll and the cylinder mold, whereby the liquid-impervious belt forms a liquid barrier for the stock in the vat.
