Abstract
A cleated dust control mat having a rubber or rubber-like backing in which the longitudinal edges of the rubber-like backing projecting outward from the pile surface thereon is smooth and thicker than the body of the rubber or rubber-like backing material. The thicker edges are produced by using a perforated silicone pad which is narrower than the desired width and has beveled edges thereon to provide a curved transition therein between the body and the longitudinal edges of the backing material.
