This relates to the manufacturing of reinforced materials, such as reinforced cellular materials or reinforced textiles, for example. Reinforcement is achieved by including a textile semi-finished product into the material to be reinforced, by providing the semi-finished product at the rear side of the material in a zigzag or wave-like manner and then pulling the semi-finished product through the material by a plurality of needles. Thus, the manufacturing process may be performed in a time saving manner.
