The aim of the invention is to provide a one-step method for producing panels, in particular floor panels for motor vehicles, with insulating fibres/water-absorbent nonwoven fabrics, and possibly additional absorbent layers, which can have different mechanical, physical and acoustic properties in areas (in parts) over the area and thickness of the insulating material. The main object is to provide a non-woven fabric structure in which the fiber orientation is perpendicular to the floor panel surface/wear layer.

    本发明的目的是提供一种生产镶板、特别是用于机动车辆的地板镶板的一步法方法,用隔热纤维/吸水性无纺布,以及可能的另外的吸收层,其可以在区域上(部分)在隔热材料的面积和厚度上具有不同的机械物理和声学性能。主要目的是提供无纺布结构,其中,其纤维方向与地板镶板表面/耐磨层垂直。
