This invention relates to a cushioned floor covering article wherein the mat includes a tufted carpet placed on the top side of a foam rubber sheet and at least one foam rubber protrusion integrated within at least a portion of the bottom side of the foam rubber sheet. Such an article provides effective removal of moisture, dirt, and debris from the footwear of pedestrians through the utilization of a carpet pile component. Furthermore, the utilization of a foam rubber backing also allows for either periodic heavy duty industrial-scale laundering in such standard washing machines or periodic washing and drying in standard in-home machines, both without appreciably damaging the inventive floor covering article, such as a floor mat. Additionally, the presence of integrated foam rubber protrusions within the mat structure provides an effective cushioning effect for pedestrian comfort as well as a means to prevent slippage of the article from its contacted surface. A method of producing such an inventive cushioned floor covering article is also provided.

1. A method of forming a cushioned floor covering article comprising the steps of(a) laying at least one rubber sheet optionally comprising a blowing agent to form a closed-cell foam rubber structure upon vulcanization on one side of a die having at least a first and second side, wherein said die has portions thereof removed to allow for the entry of molten rubber, wherein said removed portions of said die include openings within both of said first and second side, and wherein said die is comprised of a material which can withstand vulcanization temperatures and pressures; (b) laying a carrier fabric having a tufted pile surface extending from one side of the carrier fabric onto said at least one rubber sheet of step "a", wherein the side of said carrier fabric from which said tufted pile does not extend is in contact with said at least one rubber sheet; (c) optionally, placing solid rubber reinforcing strips around at least one of the border edges of the rubber sheet; and (d) subjecting the composite comprising the at least one rubber sheet, the die, the carrier fabric, and the optional reinforcing strips to vulcanization temperatures and pressures to (1) attach said at least one rubber sheet to the side of the carrier fabric from which the pile surface does not extend, and (2) to form at least one integrated rubber protrusion through the removed portions of the die.
