Claim Text:
1. A method for manufacturing a reinforced cellular material, the method comprising: variably aligning a needle relative to a perpendicular axis of the cellular material by an arbitrary angle between 0 and 90 degrees; producing a through-hole in the cellular material comprising foam material, by piercing the cellular material with the needle, wherein the through-hole extends from a first surface of the cellular material to a second surface of the cellular material; making available at least one fiber bundle on the other side of the second surface of the cellular material; reaching through the through-hole from the first surface to take hold of the at least one fiber bundle with the needle; and pulling the at least one fiber bundle with the needle into the through-hole in the cellular material; wherein the pulling step comprises pulling the at least one fiber bundle through a funnel-shaped nozzle prior to pulling the at least one fiber bundle through the cellular material, wherein the through-hole is produced with a cross-sectional surface such that the at least one fiber bundle is compressed while being pulled through; and wherein an orientation of the through-hole is configured to be individually adapted by varying the alignment of the needle such that the at least one fiber bundle is pulled into the cellular material with the needle at the arbitrary angle.
