Problems solved by technology

Although the fiber strips or fiber bundles obtained according to DE 103 12 534 B3 are laid as an infinitely long material, a change in speed also occurs here because the laying is carried out by means of a reciprocating movement of the conveyor chain, wherein at the deflection position may also be discontinued

Embodiment Construction

[0037] exist figure 1 The frame is marked with reference numeral 1, which can form a side structure on a multi-axial braiding machine, to which reference image 3 . The frame 1 has a track in the form of a guide rail 2 . On said rails is a moving element in the form of a trolley 3 which can be moved by means of pulleys 4 . The trolley 3 carries the creel 5 and the unrolling device 6 designed as a through element. The creel 5 consists of a large number of bobbins 7 on which are wound individual fibers 8 as yarn material, for example carbon fibers or nylon fibers.

[0038] The individual fibers 8 are drawn off from the bobbins 7 by deflection rollers 9 and guided through the spreading device 6 . The alignment criteria for the bobbins 7 and deflection guide rollers 9 is that the drawn individual fibers 8 cannot touch each other before entering the spreading device 6 . The bobbins 7 are equipped with brakes in order to be able to adjust and control the mechanical tension in ...

Abstract

Device for applying a strip-like unidirectional fibrous layer (17) on a support which moves in the longitudinal direction of the layer comprises a spool rack forming a single component with a spreading unit (6) to control the movement in the feeding direction to the fiber sheath (10) to the placing unit (13). Independent claims are also included for the following: (1) Method for applying a strip-like unidirectional fibrous layer on a support which moves in the longitudinal direction of the layer using the above device; (2) Method for producing a strip-like multi-axial clutch; and (3) Weaving loom for producing a fiber cloth consisting of the above device. Preferred Features: The placing unit places the fiber sheath as an endless material on the support.

Description

technical field [0001] The present invention relates to a method for laying a strip-shaped, strip-shaped or web-shaped unidirectional fiber layer to a moving support, said support moving longitudinally over the resulting fiber layer, said method having the features in claims 1 a to Features described in c. The invention also relates to a device in accordance with the preamble of claim 7 . [0002] Background technique [0003] Such methods and devices belong to the prior art. It is usually used to produce multiaxial fabrics, in which a certain number of unidirectional fiber layers are placed one on top of the other in different fiber directions one after the other. The support mentioned in claims 1 and 7 is a kind of circulation conveying device for the fibrous layer placed initially, said conveying device is in the longitudinal direction of the formed fibrous layer, and thus also constitutes afterwards the multiaxial cloth Move vertically. The conveying device generally...
