VERFAHREN UND VORRICHTUNG ZUM BESCHICHTEN VON SUBSTRATMATERIAL

摘要

In a process for coating substrate material, coating material (168) is ablated in an ablation region by a laser beam in a coating chamber (160) under partial vacuum, and spreads in the form of a coating particle stream (170) in the direction of the substrate material (24), on which it is deposited in the form of a coating (172). Large quantities of substrate material can be coated. To this end, the substrate material is flat cloth, the flat cloth is passed in a continuous strip through the coating chamber, in which the partial vacuum is substantially maintained, and coated, and the coating material required is introduced into the coating chamber, in which the partial vacuum is substantially maintained.
