Abstract
An impact resistant provided PMMA moulding material according to DE 195 44 563 is process into a surface-hardened film which is highly glossy, essentially free of gel bodies and can be processed in the “in-mould-film-decoration” method. The melted mass is generated by means of an extruder and fed to the inventive glazing rolls via a flexible lip nozzle, saild rolls being configured in order to generate an especially high locking pressure in the roll slit. The smoothing rolls are cambered. The films are used for decorating surfaces of high-value thermoplastic moulded parts.
