The base 60 can be cut in any predetermined lengths and widths at a cutting station during the fabrication process as the formed roll leaves the forming stations. However, the base 60 can consist of any other material that can satisfy the condition of rigidity on a Rockwell C scale like polyethylene, polypropylene, vinyl, nylon, various impregnated or laminated fibrous materials, various plasticized materials, cardboard, paper, etc. The thickness of the base 60 can be typically 2 mm to 4 mm and the overall dimensions depends of the applications. The color of the base 60 can be clear, semi-transparent or colored plastic to give ornamental variations to the carpet 68. The outer four corners of the base 60 are typically beveled or rounded to avoid snagging and personal injury. The base 60 can be cut in various shapes for example rectangular, trapezoidal, circular, semi-circular, elliptic, semi-elliptic, etc. The runner 51, shown partially peeled back, is a common carpet, a short or deep pile carpet, a foot cloth or felt and can be cut in the same various shapes like the gripper.
