Abstract
A process for the application of tear resistant edge strip material to a rubber base sheet of a launderable dust control mat is provided. The process involves the in-line mating of first and second strips of carboxilated rubber to the longitudinal borders of a rubber sheet by means of a series of pressure rolls. The process permits separate rubber sheet and side strip materials to be joined in a continuous or semi-continuous operation immediately prior to assembly of a mat thereby enhancing material handling efficiencies. An apparatus for carrying out the invention is also provided.
