<p>Non-slip covering sheet (1) for covering surfaces overlaid with fabric that on its lower surface (4) to be connected with the fabric overlying the surface to be covered, on the entire surface or on its one or more parts, has antislip protrusions (5) for the antislip engagement with the free fibres of the fabric overlying the surface to be covered, and its antislip protrusions (5) are constituted by suitably rigid and strong roughening particles (7, 5) fixed with a random orientation to its lower surface (4) and at least some of the antislip protrusions (5) are such that their height is between 40 microns and 3000 microns and their perpendicular projection to the lower surface (4) is bigger than their section with the lower surface (4). The non-slip covering sheet (1) is wound up in a reel (2) around a winding core (16) and/or has a size smaller than or equal to 20 square metres.</p> |
