ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to the field of underlays for rugs; and more particularly to the field of underlays for area rugs as distinguished from carpets that are fastened to the floor.
2. Description of Related Art
U.S. Pat. No. 4,504,537 to applicant, Charles S. Mussallem, Jr. teaches a rug underlay having a fiber batting needle-punched to a central stiffening lattice of heavy synthetic filamentary material; one of the two outside surfaces being treated to heat-fuse the fibers and rolled to a corrugated appearance and the other side being coated with a rubbery latex and rolled to provide an embossed grid pattern on the rubber coating.
BRIEF SUMMARY OF THE INVENTION
The present invention is an improved rug underlay made from a needle-punched fiber batting that does not include a stiffening lattice. The central core of the needle-punched batting is heat fused on one side and rolled to produce a pattern of ridges and valleys in a chevron formation, while the other side is coated with a rubber latex and embossed with a roller to impart a grid pattern onto the rubber. The heat-fused fibers of the first side are rolled to provide an overall checker-board design of ridges arranged in the style of chevrons oriented in the direction of travel of the users of the rug which is generally lengthwise of the underlay. Alternate squares of the checkerboard design exhibit the chevrons rotated 180 degrees from the direction of the neighboring square. Preferably, the central axis of each chevron corresponds to the general direction of travel of persons walking on the rug.
