The invention relates to a process, a facility and a continuously operating stamping press for the manufacture of product board which is made from a mixture provided by a spreading station in a continuously operating production press through the application of pressure and heat, and subsequently undergoes a texturing process. The invention consists of the following process steps: a) The panel, which was just released from the pressing process and still hot, is sprayed with spray water to cool the cover-layer. b) Subsequently, an increasing steam pressure is built up in a stamping press with a circulating texture belt. c) The panel is subjected to stamping pressure and a plasticizing temperature within the next section of the pressing section L of the stamping press. d) Subsequently the panel undergoes a drying and texture-fixing section with decreasing stamping pressure and temperature until it reaches the end of the stamping press section L, whereby the duration of the passage of the panel through the texturing device is sufficient to permanently fix the imprint in the cover-layer of the panel.
