Variable number of threads in braiding machines

A new embodiment of a braiding machine was developed at the Institute of Aircraft Design (IFB) of Stuttgart University. It features a thread positioning unit which forms a secondary ring of horn-gears close to the braiding point. This secondary ring moves synchronously with the primary horn-gears of the braiding machine. Therefore, the position of each thread, that is close to the mandrel, is clearly defined. This is a basic requirement for manipulation of specific threads during the braiding process, which in turn permits the automated production of components with highly varying diameters at a constant braid angle.
