A conventional method for producing pile carpet, e.g. pile carpet whose pile fibers are tufted into a support layer, consists in providing the back side of the support layer with a non-woven and in linking said nonwoven with the support layer and with the dorsal fibers of the pile fibers by hydrodynamic needle-punching. The aim of the invention is to provide the support layer with a back of its own which preferably consists of a fusible fiber. The support layer may also contain said fibers. The pile fibers are tufted into the composite support layer, the back of the intermediate product is covered with an additional fleece which consists preferably of the fusible fibers, all the components are hydrodynamically needle-punched, and the product is heat-treated in order to melt the fibers.
