Abstract
The invention relates to a method for reinforcing a predetermined edge region of a hole in a hole region of a workpiece, the edge region comprising an edge of the hole, the hole region comprising thermoplastically bound fibers, preferably a thermoplastically bund fiber tangle, comprising the steps: providing the workpiece with a softened thermoplastic binder at least in the hole region, penetrating the hole region of the workpiece in a penetration direction with displacement of fibers with a spike, after penetration: scraping fibers from the spike contrary to the penetration direction by a scraper part mobile relative to the spike, and compacting the predetermined edge region surrounding the spike with a pressing surface of the scraper part relative to workpiece regions of the hole region located radially outside the edge region.
