An apparatus and process for molding the edges of a board-shaped blank with plastic material. A one-piece mold is provided made of a material with rubber-like elasticity and having a C-shaped cross section. Two free legs of the mold receive between themselves the edges of the blank and rest against the blank from the top and bottom. The mold is surrounded by a divided mold box, having upper and lower parts supporting the mold on all sides and being compressible perpendicularly to the plane of the blank. Upon compression, free legs of the mold are forced against the blank. In the mold box, spacing elements are arranged on top of and beneath the blank to limit the distance of movement of the parts of the mold box and the compression of the mold. |
