ABSTRACT:
Machine, in particular a tissue machine, for production of a web of tissue material. The web of tissue material is produced by supplying at least two stock grades to a multilayer flow box, winding up the tissue web on a reel of a reel-up, and maintaining a winding nip having a line pressure of less than or equal to 0.8 kN/m to influence the hardness of the reel produced, in a machine that includes a multilayer flow box structured and arranged to supply at least two stock grades, an endless supporting belt, a drying cylinder and an opposing unit arranged to form a press nip, wherein endless supporting belt guides the web through the press nip, a reel-up for reeling up the tissue web, and a device to influence, in a predefined way, a hardness of a reel produced as the tissue web is reeled. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
