Abstract
The invention relates to a method for the production of a web composed essentially of a granulate and a polymer. In order for the web to have good suction against the substrate after it has been laid on a floor, the interstices between the granulate particles are not allowed to be filled with the polymer. According to the invention, this is brought about in that the polymer is applied to the top side of the granulate. After the polymer melts, the polymer seeps down through the granulate. By means of targeted control or regulation, this sinking process is influenced before the polymer reaches the underside of the web. The invention also comprises a sensor and the product as such.
