Abstract: A method for reusing loose, rejected or scrapped mats (1) of the type having a compact rubber-cloth backing (2) with a textile pile (3) incorporated therein, as well as a circumferential, pile-free backing edge portion (4, 4'), is disclosed. After optionally shaving off pile to produce the circumferential, pile-free backing edge portion, two such mats of essentially the same size, or one such mat and a pile-free rubber cloth of essentially the same size, are put together with the pile sides facing one another, or with the pile side facing the rubber cloth. Then, the edge portions (4, 4') are attached to one another throughout the entire circumference in an air-entrapping manner, whereby to obtain a mat especially suited for use on working sites or in industry.
