US 8,187,402 B2 · Method for producing a multidirectional fabric web

Abstract

The invention relates to a method for the continuous production of a multidirectional fabric web. The object of the invention is to create a method for the continuous production of a multidirectional fabric web that has a material layer running in a longitudinal direction and thus has sufficient stability against distortions in the fabric. This object is achieved according to the invention in that a continuous fold-winding process of at least one fiber layer running at an angle to the direction of extension of the fabric web to be produced takes place with the enclosing of at least one material web (1) running freely in the spread-out state in the production direction at least in the fold-winding zone. The invention can be used in the production of fabric webs that are used for example as a reinforcement of high-strength plastics.

Dependent claims

A method for the continuous production of a fabric web, comprising:

feeding at least one fabric layer having a spread-out flat fiber structure at an angle to a production direction;
and
converting the at least one fabric layer to a multilayer, multidirectional fabric in a continuous fold-winding process that encloses at least one material web running freely in the production direction,
wherein the continuous fold-winding process includes the at least one fiber layer being folded before being placed on the respective edge of the material web.
