Abstract (en)
[origin: EP0023980A2] 1. A device for radiating the surface of a workpiece having a fan blowe (4) and having at least two supply tubes (1, 2) for a radiation medium, which tubes open off centre substantially perpendicular to the fan blower (4), characterised in that the angle in each case between the aperture of the first (1) and the second (2) supply tubes is selected with respect to the direction of rotation of the fan blower (4) such that radiation areas which vary in size and position and which have adjustable boundaries are obtained, and in that the supply tubes (1, 2) may be actuated separately or together at will.
