ABSTRACT:
The mechanical device used for carrying out the procedure consists of a reel (B), upon which is wound a conveyor sheet. Before the sheet is wound onto the said reel, the retroreflecting elements (A) are attached to it, maintaining a certain preestablished spacing between the elements. When the sheet is made to unwind from the reel (B) and passed over the sharp-edged body (C), the retroreflecting elements (A) are mechanically detached from the sheet and deposit themselves onto the road surface (S), maintaining the same preestablished spacing between them. The sheet, from which the retroreflecting elements have been detached, is then rewound onto the rewind reel (E).
The surface of the said sheet (B) can either be coated with an adhesive (sticky) substance, while the surfaces of the retroreflecting elements (A) are treated with a detaching polymer, or the sheet surface can be treated with the detaching polymer, with the surfaces of the retroreflecting elements coated with the adhesive (sticky) substance.
