Abstract

A woven fabric for a fiber web producing machine has a defined machine direction, a cross machine direction, a web facing side, and a machine side. The web facing side is formed by MD yarns that extend substantially in the machine direction and by CD yarns extending substantially in the cross machine direction of the woven fabric. The MD yarns and CD yarns are interwoven with each other and the woven fabric is configured to structure the fiber web produced on the woven fabric. A plurality of adjacent long flotations of MD yarns on the web facing side form together a discrete element that is raised on the web facing side for allowing the woven fabric to structure the fiber web. The term “long flotation” means that the MD yarn passes over at least six adjacent CD yarns on the web facing side of the woven fabric.

Dependent claims

A woven fabric for use in a machine for producing a fiber web, the woven fabric having a machine direction, a cross machine direction, a web facing side, and a machine side, the woven fabric comprising:

mutually interwoven machine direction (MD) yarns and cross direction (CD) yarns forming the web facing side with said MD yarns extending substantially in a machine direction of the woven fabric and said CD yarns extending substantially in a cross machine direction of the woven fabric;
wherein the woven fabric is configured to structure the fiber web produced on the woven fabric;
a plurality of mutually adjacent long flotations of said MD yarns on the web facing side together forming a discrete element that is raised on the web facing side of the woven fabric for enabling the woven fabric to structure the fiber web, with long flotations being formed by an MD yarn passing over at least six mutually adjacent CD yarns on the web facing side of the woven fabric.
