Abstract
A sandwich structure reinforcement carried out by a gripper, which pierces the sandwich structure or the core material, only at one side, thereby obtaining a hole penetrating through, e.g., a polymer rigid foam. At the opposite side, the gripper catches the reinforcing structure (for example a sewing thread, pultruded fiber-plastic composite rods) and inserts the reinforcing structure into the sandwich structure during back movement thereof. The through hole is additionally enlargeable by the reinforcing structure, thereby making it possible to obtain an important fiber volume part in the through hole of the core material.
