ABSTRACT:
For the marking of gas-permeable fabric or cloth webs and other material webs, especially for the automatic marking in a marking station, the invention proposes to contact the fabric web within the marking station with a film including the pattern to be marked off in the form of perforations and acting as a stencil, and to suck atomized paint (paint mist) through the perforations and the contacting fabric web, wherein this atomized paint is an aerosol produced by atomization of a liquid containing a dye or pigment dissolved therein. Advantageously, a fluorescent dye is used to this end. A corresponding apparatus comprises, below the fabric web, an atomizing chamber equipped with nozzles for producing the atomized paint, with the film being positioned on the gas-permeable upper side thereof, as well as, above the fabric web, a vacuum compartment having a gas-permeable lower side in the form of a grate, and a resilient, gas-permeable (pressure) cushion attached to the grate and acting to hold down the fabric web on the film, and, further, means for generating a vacuum, and a control unit controlling the cooperation of the functions.
