The invention relates to a method and a system for producing a multi-layer thread or fibre arrangement (GF) which is pre-fixed by means of a loop structure and is used a s a strip-type semi-finished product for reinforcing elements consisting of plastic or resin. Said fibre arrangement (GF) comprises layers consisting of stationary weft yarns (K) and layers consisting of thread or fibre warps (S, D,D') which are stretched between conveyor chains in such a way that they are oriented in different directions. The aim of the invention is to reduce the costs and the required surface mass, simultaneously maintaining defined, required flexural strength. To this end, the method is designed in such a way that the stationary weft layer (KR) consisting of fibre or thread warps and oriented parallel to the working direction is located directly adjacent to the needle loops (WN) of the loop structure, and needle loops (WNv) of the loop structure cross the threads or fibres of the stationary weft layer, in the knock-over phase, before the knitting needles () penetrate the thread arrangement (G) in order to create a successive row of loops.

Method and system for producing a multi-layer, pre-fixed thread or fiber arrangement

The invention is directed to a process and a device for the production of textile net-like fabrics by various bonding processes, e.g., the warp knitting process or stitch bonding process. Based on the object of the invention--to provide a process and a device for carrying out the process for producing textile net-like fabrics with threads which are continuous in the working direction and transversely thereto and which form mesh sides of the net, with large mesh widths, a high variability of structure, and product widths extending beyond the working width --a plurality of adjacent groups (4) of mesh side threads forming the mesh sides in the working direction are produced, a function thread (12) is guided from one longitudinal side of the fabric to be produced to the opposite longitudinal side of the fabric to be produced in order to form the other mesh side lying transversely to the working direction, the function thread is temporarily set in its position transversely to the working direction at least at two setting points arranged adjacent to one another transversely to the working direction, the function thread is formed into at least one loop in order to form function thread reserves (13) between two setting points arranged transversely to the working direction, the function thread which is provided with at least one function thread reserve and is temporarily set transversely to the working direction is tied on or tied in at the same time at least at two adjacent groups of mesh side threads, and the temporary setting of the function thread is canceled.
