The reinforcement structure is produced by the lay up of a single roving. This roving is fixed by stitching to the base material.

The base material can be a 2D-textile such as a woven fabric or for thermoplastic composites a matrix-compatible foil material.

During the process, the stitching unit is stationary and the base material is moved using numerical control. To became economic we use up to 30 working units and a high stitching speed.
