Abstract

The present invention relates to a method for the continuous production of laid staple fiber fabrics with aligned fiber orientation, in which method the laid fabrics are produced by continuous plaiting down of carded fiber web at defined laying angles onto a synchronized transport belt (1), wherein the carding machine (2) and plaiting means (3) arranged downstream of it are arranged at an acute angle with respect to the advancing direction of the transport belt. Said laid staple fiber fabrics are used for producing high-strength fiber-reinforced plastic composites, as are used in wind power plants, aircraft construction and the automotive industry. In particular in the loading direction, said composites have high composite strengths and rigidities, to which end a defined fiber orientation is required. In addition to a defined orientation of the finite fibers, the laid fabrics also have a defined mass per unit area.
