Embodiment Construction

[0036] figure 1 A top view of a first embodiment of the invention is shown. figure 1 And the following figures are only schematic diagrams, which should show important parts. according to figure 1 Place the unidirectional fiber layer onto support 1. Carriage 1 moves in direction 2 , ie in the illustration from top to bottom. The carrier 1 can generally be formed by two conveyor chains 3 , between which the individual sections 18 are clamped in clamping devices (not shown) and thus also supported. The next processing station is indicated with reference numeral 4 . For example, the reference numeral 4 may designate a bobbin on which the finished unidirectional fiber layer is wound in this respect. However, the reference numeral 4 can also designate the next section supply station, in which, for example, a next unidirectional fiber layer is laid on an already existing fiber layer. if in figure 1 The unidirectional fiber layer shown in is the uppermost and last fiber layer ...

Abstract

The invention relates to a device for laying a unidirectional fiber layer formed by a plurality of segments 18 on a mobile bracket 1, wherein the mobile bracket 1 is provided with two segment-feed stations 5a, 5b along the movement direction; each segment-feed station comprises a storage unit 6a, 6b and a paving device 12a, 12b; yarn clampers 10a, 10b are used for extracting parallel fibers from the storage units 6a, 6b; the fibers are cut out based on a fixed length and are paved on the bracket 1 by the paving devices 12a, 12b; the bracket 1 is formed by two annular conveying chains 3 in an ordinary mode; a station 4 is used in the following process, such as winding the produced unidirectional fiber layer on a yarn roller; the two segment-feed stations 5a, 5b are arranged along the movement direction and longitudinal direction of the bracket 1 one by one and are paved above clearance; a first segment-feed station is paved with a segment 18 having a clearance 19; and a second segment-feed station 6b is accurately filled in the clearance 19 by matching with the paved segment. In such a manner, the production rate is greatly increased.

Description

technical field [0001] Method and device for laying unidirectional fiber layers as well as method and multiaxial weaving machine for producing multiaxial cloth. [0002] The invention relates to a method for applying a strip-shaped, strip-shaped or web-shaped unidirectional fiber layer consisting of individual segments to a mobile support according to the preambles of claims 1, 13 and 16. Background technique [0003] Such methods and devices belong to the prior art, eg from EP2003232A1. The unidirectional fiber layers described in the present invention are generally used to make multi-axial cloths, wherein a certain number of unidirectional fiber layers are stacked segment by segment with different fiber directions. A carrier in the sense of the present invention is an endless conveying device for the initially deposited fibrous layer which is moved in the longitudinal direction of the formed fibrous layer and thus of the subsequently formed multiaxial cloth. The conveyin...
