摘要： The invention relates to an apparatus and a method for depositing synthetic fibers to form a non-woven web, in which method the synthetic fibers are guided in the form of a blowing stream through a drawing unit for being deposited on a deposit belt. For this purpose, inside the guidance distance between a blast opening of the drawing unit and the deposit belt, several guidance means are arranged, which form a guidance channel above the deposit belt, wherein the guidance means form a channel opening of the guidance channel at a distance from the blast opening of the drawing unit. In order to achieve constant strength in the deposition of the fiber strands in the non- woven web, the distance between the outlet of the drawing unit and the channel opening of the guidance channel is larger than half the guidance distance according to the invention, wherein the guidance width of an open space formed between the outlet of the drawing unit and the channel opening of the guidance channel is larger than that of the guidance channel.
摘要翻译：本发明涉及一种用于沉积合成纤维以形成无纺网的装置和方法，其中合成纤维以吹塑流的形式通过拉伸单元被引导以沉积在沉积带上。为此，在绘图单元的鼓风孔和沉积带之间的引导距离内布置有几个引导装置，其形成在沉积带上方的引导通道，其中引导装置形成引导通道的通道开口距离绘图单元的鼓风开口的距离。为了在纤维束在非织造网中的沉积中获得恒定的强度，拉伸单元的出口与引导通道的通道开口之间的距离大于根据本发明的引导距离的一半，其中在引导单元的出口和引导通道的通道开口之间形成的开放空间的引导宽度大于引导通道的引导宽度。
