Abstract
Abstract An improved carpet runner for self-service sales in discount stores or the like without the need for assistance of a clerk. The runner includes an elongated web of flexible, liquid-impervious plastic material having on one side thereof a plurality of projections for gripping the nap of an underlying carpet. The improved runner includes a plurality of substantially equally spaced, liquid-impervious, transverse lines of weakening extending across the web so that a desired predetermined length of the web may be easily separated from the remainder of the web along a desired one of the lines of weakening without the use of a tool.
