An apparatus for dyeing leather has an application roller and a backup device defining a gap therebetween. The application roller has recesses, and dye is supplied to it to fill the recesses. Sheet articles, e.g. leather pieces, are fed through the gap. The apparatus is operated so that a uniform coating of dye is continuously spread over one surface of the article by the application roller. The dye can have a low viscosity comparable to that of water. |
