Embodiment Construction

[0030] exist figure 1 shows a part of a device 1 for producing fibrous nonwovens with a known card 20 having an input side 21 for fiber bundles and one or more outputs for fiber webs 30 side 23. Arranged upstream of the input side 21 of the card 20 is a feeder 10 , for example a vibrating vertical feeder (Rüttelschachtspeiser), with which the fiber bundles are deposited onto the conveyor belt 11 . In addition to the vibrating vertical feeder, the card 20 can also be equipped with a card feeder with an integrated nonwoven thickness measuring device, in which the weight is determined via the nonwoven thickness measuring device .

[0031] In the carding machine 20, the fiber bundle is fed on the input side 21 of the device and is guided to the main cylinder (Tambour) 22 by elements not depicted in more detail, such as feed rollers, pre-combing cylinders and transport units, so that the fibers are The bundles are opened into individual fibers and oriented. During the conveying...

Abstract

The invention relates to a device and a method for making a multi-layer nonwoven fabric from at least one loose fiber web. The device is provided with at least one carding machine (20) used for manufacturing a fiber web, and is provided with at least one device used for stacking loose fiber layers on a conveyor belt along a conveying direction of a material. The loose fiber layer can be conveyed to a fiber web (30).The device and the method are advantageous in that the loose fibers are conveyed to the area of the fiber web (30), which is provided with a fixing device (40), and the fixing device is used for fixing the fiber web (30) by using a first pressing part (42) and a first fixing part (43).

Description

technical field [0001] The invention relates to a device and a method having at least one card for producing a fiber web and downstream in the material conveying direction at least one device for depositing loose fiber layers on a conveyor belt , wherein the loose fiber layer can be transferred to the fiber web. The invention also relates to an inclined screen forming machine. Background technique [0002] During the production of wet-laid fibers, these fibers are often combined with different fiber qualities. For this reason, according to prior art (document EP 1929080B1) syncline screen forming machine A spunbond or card nonwoven is conveyed, which is unwound by an unwinder arranged upstream of the inclined screen forming machine in the flow direction of the material. The spunbond or carded nonwoven is usually prefixed so that it does not cause confusion when the wet-laid fibers are deposited on the nonwoven and further processed together. [0003] Furthermore, it is ...
