Embodiment Construction

[0092] figure 1 A winding device 1 is depicted, which can be used in a method for continuously producing a multiaxial fabric web. In the winding device 1 there are two winding rollers 2 and 3 , from which the fiber material 4 is unwound and formed into a multiaxial fabric 5 . The winding rollers 2 and 3 are arranged stationary, which means that they do not move in space, but otherwise rotate about their own axis in order to be able to unwind the fiber material 4 . Parallel to the extension of the multiaxial fabric 5, two tensioning elements 6 and 7 are tensioned in the winding device 1, which are unwound from rollers 8 and 9 and serve as a boundary for a plane which passes through the two tensioning elements 6 and 7 form. The synchronously rotating tensioning elements 6 and 7 by means of rollers 8, 9, a calendering and separating device 10 and a winding device 11 rotate about an axis parallel to the two tensioning elements 6 and 7 and extending centrally.

Abstract

The invention relates to a method for the continuous production of a multiaxial contexture web, in which a uniaxial contexture (4, 102, 103, 302, 303, 402, 403) is shaped to form a multiaxial contexture (5, 101, 301, 401) by winding about a plane (104, 306, 406), and to a corresponding apparatus for carrying out the method according to the invention. According to the invention, in order to accelerate the production method and for improved handling of the contextures (4, 5, 101, 102, 103, 301, 302, 303, 401, 402, 403) during the production process, there is provision for clamping elements (6, 7) to be used as delimitation of a plane (104, 306, 406), around which the uniaxial contexture (4, 102, 103, 302, 303, 402, 403) is wound. Furthermore, in order to reduce the friction during the production of the multiaxial contextures (5, 101, 301, 401), there is provision for at least one belt or band drive (105) to be used which runs along two side edges (106, 107) which lie opposite one another. Furthermore, there is provision according to the invention for a unidirectional contexture (4, 102, 103, 302, 303, 402, 403) to be wound at an angle around a plate (201) to form a reel, wherein the plate (201) is provided with an apparatus for compensating for friction and the reel (245) is pulled off from the plate (201). In addition, it is proposed to set the winding plane (104, 306, 406) in mechanical oscillation during the winding operation, in order to pull off the multiaxial contexture (5, 101, 301, 401) from the winding plane (104, 306, 406) with a low frictional resistance as a result of the oscillations. Furthermore, it is proposed to select an oblique position of the longitudinal axis (407) of the winding plane (104, 306, 406) in relation to the direction of gravity (408).

Description

technical field [0001] The invention relates to a method for continuously producing a multiaxial fabric web, in which a fabric is formed into a multiaxial fabric by winding around a plane, and to a device for carrying out the method. Background technique [0002] Fiber composite components reinforced with long fibers are an important field of application for technical textiles. The structure and organization of the reinforcing fabric in combination with the manufacturing process and the applied matrix material decisively determine the properties of the subsequent composite component. The above-mentioned multiaxial fabrics, likewise MD or multidirectional fabrics, play a special role here, because compared with other fabrics, they allow a planar structure, which provides a higher degree of characteristic properties of the fibers used. Utilization, while reducing manufacturing costs and thus component costs. [0003] Different techniques are used for producing multiaxial fab...
