The plastic protector (5) covers only a limited region of the plastic sheet, lying opposite the injection inlet (4). Plastic injection-molding mass is injected into the mold (2), melting the protector. Protector melting is sufficient that the entire rear (1a) of the sheet is covered by it, or it becomes completely distributed into the injection molding mass. Preferred features: The protector, a plastic sheet, is at least lightly bonded to the plastic sheet before rear-injection. In a variant method, the protector in the form of a suitable molding, is plugged into the mold inlet for plastic mass.
