Method of removing dents from sheet-metal parts, in particular from lacquered parts of an automobile body, wherein the metal part ( ) in the region of a dent (B) is warmed locally in a substantially non-contact manner, in such a way that a mechanical tension gradient produced by the local warming causes the dent to spring back so as to restore the original shape of the metal part.

Method and device for removing dents from sheet metal parts

Method and apparatus for coating the surface of an object, especially the surface of a car bumper ( ) with a plastic film ( ). During and/or after application of the plastic film to the surface, the 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 ( ). 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.

Method and device for coating a surface with a plastic film

A method and an apparatus for drying a substance that is being rapidly conveyed in a conveyor apparatus, in particular for drying layers of printing ink on rapidly transported paper, wherein in a drying zone by means of incident electromagnetic radiation a moisture component, in particular a solvent, is separated from the substance to be dried. The separated moisture component is transported away from the drying zone by means of a transport gas current. Efficient and rapid drying of in particular printed newsprint or thermal printing paper is attained at high conveyor velocities.
