Abstract
A method for realising ceramic slabs or tiles, comprising the following steps: laying a soft layer (SL) of granular or powder ceramic material on a support plane (P); pressing the soft layer (SL) in order to obtain a compacted layer (CL); firing the compacted layer (CL); prior to the pressing, applying an identification mark (M) onto the soft layer (SL), the identification mark (M) having an optical contrast with respect to the soft layer (SL), so as to enable an optical detection of the mark (M); subsequently to the pressing, acquiring an image of the mark (M); processing the image of the mark (M) detected so as to control one or more operating steps subsequent to the pressing.
Claims16
A method for realising ceramic slabs or tiles, comprising the following steps:
- laying a soft layer (SL) of granular or powder ceramic material on a support plane (P), the laying of the soft layer (SL) comprises a step of laying an edge zone (E) of the soft layer;
- pressing the soft layer (SL) in order to obtain a compacted layer (CL);
- firing the compacted layer (CL);
- wherein,
- prior to the pressing, applying an identification mark (M) only onto the edge zone (E) of the soft layer (SL), the identification mark (M) having an optical contrast with respect to the soft layer (SL), so as to enable an optical detection of the mark (M);
- subsequently to the pressing, acquiring an image of the mark (M) and removing the edge zone (E) and the entire identification mark (M) from the compacted layer (CL);
- processing the image of the mark (M) detected so as to control one or more operating steps preceding and/or subsequent to the pressing of the soft layer (SL).
