Abstract
A disclosed method for manufacturing a floor covering includes the steps of vulcanising a support layer made of an elastomer and assembling an intermediate layer to the support layer during the step of vulcanising, wherein the intermediate layer is made of a material selected from the group that includes polyester, polyetheretherketone, polyetherimide, polysulfone, polyimide, polyamide, fluoropolymer, polyurethane, and paper. A print layer is printed either the intermediate layer or a transparent protective layer. When the print layer is printed on the intermediate layer, the protective layer is assembled to the print layer of a set that includes the print layer, the intermediate layer, and the support layer. When the print layer is printed on the protective layer, the print layer of a set that includes the print layer and the protective layer is assembled to the intermediate layer of a set that includes the intermediate layer and the support layer.
