Estimating the term…
The invention relates to a device and method for structuring the surface of floor coverings which have already been laid, comprising various floor coverings which may also consist of mineral materials such as natural or artificial stone. The object of the invention is to provide floor coverings which have already been laid with a structure on their surface, which structure makes it possible to at least increase the nonslip properties even in the presence of slippy media, e.g. water. To do this, the invention uses a device with which at least one laser beam can be moved with controlled intensity and in at least one dimension across the surface to be structured, the elements for guiding and shaping the laser beam(s) being accommodated in a mobile part of the device, so that this mobile part is guided intermittently or continuously across the floor surface which is to be structured and, in the process, the structuring can be formed by means of the laser beam.
A device for structuring the surface of floor coverings which have already been laid, comprising at least one laser beam which can be moved with controlled intensity in at least one dimension across the surface to be structured;
A method for structuring the surface of floor coverings which have already been laid using at least one laser beam, which can be moved with controlled intensity in at least two dimensions across the surface which is to be structured, wherein a mobile part of a device having an element which is arranged thereon and can be displaced with respect to the mobile part in two axes which are oriented perpendicular to one another, in which mobile part at least the elements for guiding and shaping the at least one laser beam are accommodated, is moved in a defined way over the surface to be structured or is positioned in that area, and the at least one laser beam is controlled as a function of the speed or position.
