    • The invention relates to an apparatus for compacting a material web made of fibers and/or filaments, comprising a first revolving endless belt which carries the material web and is tensioned around guide rollers, and a second endless belt which is tensioned around guide rollers and revolves counter to the first belt at the same speed, wherein the first and second endless belts form a conical compacting region in a first region in the conveying direction of the material web and run at an angle with respect to each other, whereby the material web located between the belts is increasingly pressed, wherein subsequent to the first region a first nozzle beam is disposed for a first fluid application onto the material web still located between the two endless belts, wherein the two belts in this region of the first fluid application are in each case guided to run in a tensioned manner in a straight direction. According to the invention, the following is provided: the two belts (1,2) are guided in the region of the first fluid application (D,W,A) such that they do not run parallel to each other, or: the two belts (1,2) are guided in the region of the first fluid application (D,W,A) such that they run parallel to each other in a first section (AB1) and not parallel to each other in a subsequent second section (AB2).
    • 本发明涉及一种用于压缩由纤维和/或细丝制成的材料网的设备,包括:第一旋转环形带,其承载材料纤维网并且围绕导向辊张紧;以及第二环形带,其围绕导辊和旋转张紧 以相同的速度与第一带相对,其中第一和第二环形带在材料幅材的输送方向上的第一区域中形成锥形压实区域,并且相对于彼此成角度地延伸,由此材料幅材位于 在带之间越来越多地被按压,其中在第一区域之后,设置第一喷嘴梁以将第一流体施加到仍然位于两个环形带之间的材料纤维网上,其中在第一流体应用的该区域中的两个带处于 每个壳体被引导以直线方向张紧地运行。 根据本发明,提供以下内容:两个带(1,2)在第一流体施加(D,W,A)的区域中被引导,使得它们不彼此平行地延伸,或者:两个 带(1,2)在第一流体施加(D,W,A)的区域中引导,使得它们在第一部分(AB1)中彼此平行并且在随后的第二部分中彼此不平行( AB2)。
