Method and apparatus for the marking of gas-permeable fabric of cloth webs and other material webs, especially for the automatic marking in a marking station
First Claim
1. A method for the marking of a gas-permeable fabric or cloth webs or other material webs for a marking station comprising:
- guiding the fabric web including inserting the fabric web in marking apparatus and severing marked fabric sections;
contacting the web with a film as a stencil positioned on the gas-permeable lower side of the fabric and including the pattern to be marked off in the form of perforations;
sucking an atomized paint through the perforations in the film from below to above the fabric web and through the contacting fabric web by a vacuum compartment having a gas-permeable lower side comprising a grate;
interposing between the grate and the fabric web a resilient gas-permeable material layer as a cushion;
abutting the vacuum compartment and the atomizing chamber against each other with the fabric web interposed therebetween and pressed down by the grate and cushion.

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.
