a textile a nonwoven fabric etc especially made of glass fibers polyester natural fibers etc the process according to the invention advantageously comprises a pregelling step between the step b of sprinkling particles onto the layer of liquid plastisol and the step c of applying pressure and heat the time necessary for the various steps of the process depends on the nature and on the amount of plastisol and particles deposited but also on the temperature and the pressure used as the pressure is relatively low and as the gelling temperature should not exceed a certain threshold in order not to completely melt the granules it is possible to adapt the speed of the conveyor belts and or their length as a function of the other parameters another aspect of the invention relates to a device in particular for carrying out the process for manufacturing a thermoplastic floor covering as described above comprising a a lower conveyor belt b an upper conveyor belt placed above a portion of the lower conveyor belt a and at a distance from the latter which corresponds to the thickness of the floor covering and that makes it possible to exert a pressure on this.
