    摘要： The invention relates to a method for manufacturing vacuum insulation panels with a fiber core, comprising the steps of: providing a core blank of fibers, compressing the core blank to a predetermined final thickness for forming the core, evacuating a foil sleeve enclosing the core up to a pressure of ≦1 mbar, and sealing the foil sleeve. The method according to the invention is characterized by the fact that, in the compression step, the core blank is arranged between two cover elements and is mechanically compressed therebetween, that the core is kept under compression pressure until the foil sleeve is sealed, and that the compression step is performed at the place of manufacture at room temperature without thermal impact. Thus, a method for manufacturing vacuum insulation panels with a fiber core can be improved such that it can be performed with reduced energy requirement and yet the insulating effect of the vacuum insulation panels does not suffer therefrom.

    摘要翻译： 本发明涉及一种用于制造具有纤维芯的真空绝热板的方法，包括以下步骤：提供纤维的芯坯料，将芯坯料压缩至预定的最终厚度以形成芯部，将包围芯的铝箔套筒抽空 压力为1毫巴，并密封箔套筒。 根据本发明的方法的特征在于，在压缩步骤中，芯坯布置在两个盖元件之间并在其间被机械地压缩，芯被保持在压缩压力下，直到箔套被密封，并且 压缩步骤在室温下在没有热冲击的地方进行。 因此，可以提高具有纤维芯的真空绝热面板的制造方法，从而能够以较低的能量需求进行，但绝缘面板的绝缘效果不会受到影响。

    摘要： The invention relates to a binderless needle felt (1) of mineral wool, comprising a plurality of fibers arranged predominantly in parallel to the large areas of the needle felt (1), and individual fibers at needling points which arranged predominantly transversely to the large areas by a needling process and by which the fibers of the needle felt (1) are felted such that the needle felt (1) is adapted to be handled as one element. This needle felt (1) is characterized in that the density of the needling points at a first large area (2) is at least 15 needling points/cm2, that the number of the fibers arranged transversely to the large areas decreases from the first large area (2) toward an opposite second large area (3) of the needle felt (1), and that a near-surface region at the second large area (3) is substantially free from fibers arranged transversely to the large areas. Thus, an improved needle felt is achieved which avoids the drawbacks in prior art and comprises an improved insulating effect with at least equivalent handling properties.

    摘要： The invention relates to a device for forming mineral fibres, comprising: a centrifuge (1) adapted to turn about an axis of rotation (9), the centrifuge (1) comprising an annular wall (10) drilled with a plurality of orifices (11), the annular wall (10) having for axis of symmetry the axis of rotation (9); a first annular inductor (2) adapted to heat the upper part of the annular wall (10); and a second annular inductor (5) adapted to heat the lower part of the annual (10). Thus, the invention allows efficiency to be increased and emission of carbon dioxide to be very greatly decreased or even prevented.

    摘要： This winding device for the formation of fibrous rolls comprises: - a first conveyor belt (3) and a second conveyor belt (4), - a movable compression roll (52) which delimits, together with guiding surfaces (37, 47) of the conveyor belts (3, 4), a winding zone (10), - a movable precompression belt (7) having an upstream roll, and a downstream assembly (74, 75, 76) having a curved downstream end (76) and a strip (71) which is wound around the upstream roll and the downstream assembly (74, 75, 76). The strip (71) held taut against the downstream assembly (74, 75, 76) forms, opposite the guiding surface (37) of the first conveyor belt (3), a moving precompression surface (79) of a fibrous mat to be wound, this precompression surface (79) being the precompression element closest to the winding zone (10).
