Fiber web surface finishing, to give a matt paper, imposes a regular and isotropic pattern by an embossed roller or metal band or particle blasting and the like

摘要

To form a matt surface on a fiber web, in a papermaking or finishing machine, the web surface is brought into contact with a roller (1,3) or a milled wheel (2) or the metal band of a calender, which imposes an isotropic and regular pattern on it. The web can be coated or uncoated, with a low gloss. The web surfaces can also be blasted with particles to roughen it and give a matt effect.
