METHOD AND APPARATUS FOR COATING A SURFACE WITH A THIN PLASTIC SHEET

摘要

The invention relates to a quality control for coating the surface of an object, especially the surface of a car bumper (1) with a plastic film (2). During and/or after application of the plastic film to the surface, said coating is irradiated with infra-red radiation in order to heat at least parts of the coating and/or optionally residual moisture between the surface and the plastic film (2). This enables slight inequalities of the plastic film to be compensated, the adhesive coating is distributed in a homogeneous manner and the optionally residual moisture is collected in the form of bubbles following infrared radiation. Defects or irregularities in the coating can thus be identified during or shortly afterwards radiation.
