ABSTRACT:
A method of manufacturing a floor covering presses a bottom layer of a polymeric material into apertures in a top layer having a higher pressure-flow viscosity than the bottom layer. The pressure also joins the layers into the floor covering and forms a continuous pressure-vulcanization skin on the top thereof for more uniform soiling and wear characteristics. Selecting the size and arrangement of the apertures in the top layer produces a corresponding pattern of the bottom-layer material in the top of the joined layers which is independent of any surface configuration also imparted in the pressing.
