Abstract (en)
[origin: WO2013045997A1] A surface element ( 1 ) for friction increase comprises a lying portion ( 2 ) defining a reference surface, and engagement means ( 3 ) that can be extended and/or recessed relative to the reference surface and is suitable for interfacing with corresponding engagement means of a faced surface element for friction increase; the surface element further comprises a predetermined number of clusters ( 4 ) of the engagement means defined by respective confining edges ( 4a) and distributed on the lying portion, and in each of these clusters the engagement means is disposed along directrices ( 4b) having at least one predetermined curvature ( 4c ) and one corresponding centre of curvature, centres of curvature of directrices belonging to clusters separated from each other not being coincident.
