Abstract (en)

[origin: WO2011035782A1] The invention relates to a system and method for producing glass fiber fibrous non-woven fabric (FL), and to the non-woven fabric (FL) produced using same, in particular as a semi-finished product or final product, which is used preferably for damping and/or insulating purposes. The system for producing glass fiber fibrous non-woven fabric comprises a fiber opening device for dispersing the glass fibers and aligning the glass fibers in an oriented or non-oriented manner and forming a fibrous web (F), a first unit (3) for reorienting the oriented or non-oriented fibers of the fibrous web (F) into fibers that assume a random position, wherein the volume of the fibrous web (F) is increased/the density of the fibrous web is decreased, an elevating belt (2), which conveys the fibrous web (F) from the fiber opening device to the first unit (3), and a second unit (4), on which a homogeneous one-layer fiber non-woven fabric (FL) having fibers in a random position is formed from the fibrous web (F) of the first unit (3) on a laying belt (7), the weight per unit area of the homogeneous one-layer fiber non-woven fabric being a multiple of the weight per unit area of the fibrous web (F).
