Abstract: Method and apparatus for producing a scrim. The method includes depositing several band sections next to one another on a conveyor device that at least temporarily moves in a direction of transport. The direction of transport is oriented at a predetermined angle to a band direction and each band section has a front edge running in the band direction and a rear edge running in the band direction. The method also includes placing the band sections so that the rear edge of a first band section is adjacent the front edge of a second band section, calculating a rear-edge shape of the first band section and a front-edge shape of the second band section and placing the second band section on the conveyor device relative to the first band section as a function of a relation between the front-edge shape and the rear-edge shape.

Abstract: Method and device for producing a unidirectional (UD) layer with a predetermined layer width from a predetermined number of filament strands. The method includes spreading the filament strands out transversely to a longitudinal direction of the UD layer to form bands that are arranged next to one another. A first width of the bands is greater than a dividing width, which corresponds to the predetermined layer width divided by the predetermined number of filament strands.

The method includes supplying a web having a main direction, a plastic matrix, and a plurality of fibers fixed in a unidirectionally oriented manner enclosing an angle of about 0° to the main direction, separating segments from the supplied web, arranging the separated segments next to one another so that longitudinal edges of adjacent segments are parallel to the main direction and to one another, and enclose the predetermined angle (a) to the longitudinal direction, and connecting the adjacent segments in a region of their longitudinal edges.

Abstract: Method and device for producing a composite material. The method includes feeding at least two semi-finished webs in their respective longitudinal direction, placing one of the at least two semi-finished webs on top of an other of the at least two semi-finished webs, and connecting the at least two semi-finished webs to one another. Each semi-finished web has fibers fixed in a unidirectionally oriented manner, and, in at least one of the at least two semi-finished webs, the fibers enclose a predetermined angle greater than 0° to the longitudinal direction.

Abstract: The invention relates to a method for the continuous production of a multidirectional fabric web. The object of the invention is to create a method for the continuous production of a multidirectional fabric web that has a material layer running in a longitudinal direction and thus has sufficient stability against distortions in the fabric. This object is achieved according to the invention in that a continuous fold-winding process of at least one fiber layer running at an angle to the direction of extension of the fabric web to be produced takes place with the enclosing of at least one material web (1) running freely in the spread-out state in the production direction at least in the fold-winding zone. The invention can be used in the production of fabric webs that are used for example as a reinforcement of high-strength plastics.

Abstract: Process and apparatus for laying fiber bands of filaments by changeably moveable weft or diagonal layers to form fiber arrangements stretched in different laying directions between two transport chains having guide hooks and retainer needles. Fiber bands are spread individually, guided by guide elements for forming a direction change fold, such that strands of each direction change fold are fixed in gaps between guide hooks. Apexes of direction change folds spread out by the guide elements execute racking and are hanged and fixed in a row of densely arranged retainer needles. Upper strands of direction change folds forming between retainer needles and guide elements of weft or diagonal layers are spread horizontally and guided under tension by a stitch spreader moved from outside inwards. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
