Document Type and Number:
Japanese Patent JPS61501461
Kind Code:
A
Abstract:
It is a known phenomenon that the web during the drying moment in a paper machine shrinks. The shrinkage in the machine direction can be controlled by arranging the different driving groups in the drying section to operate at different speeds. The shrinkage in cross direction, however, heretofore was not brought under control. The present invention has the object to solve thos problem.
According to the invention, the problem of shrinkage is solved in that the web during a certain drying interval is subjected to outward directed forces, which are applied during a suitable drying interval and preferably at a low dry content, for example directly after the press section.
