<p>The present invention pertains to the field of techniques for recycling industrial waste and more precisely relates to techniques for recycling used tyres. The purpose of this invention is to increase the volumetric compacting density of the materials to be recycled, i.e. the rubber and metallic cord, during the transportation and recycling processes of used tyres. To this end, the method of the present invention first comprises separating the tyres into tread and side-wall portions. The tread portions of the tyres are cut in the radial plane and wound into a spiral-shaped strip. In one aspect of this method, the spiral-shaped strip comprises a plurality of tread portions which are sequentially wound one after the other. In another aspect of this method, the side-wall portions are arranged one onto the other with the convex part on the same side so as to form a pack in the shape of a cylindrical ring.</p> |
