A laminate comprising a support component in the form of a first web of fibres and/or filaments, and a component with loops in the form of a second web of fibres and/or filaments, the two components being fixed to one another, wherein the fixing causes S-shaped calendering islands to appear on the exterior surface of the component with loops in the shape of an S with two symmetrical heads, characterised in that each S-shaped calendaring island consists of two sub-islands forming said symmetrical heads and an intermediate, non-fixed region separating the two sub-islands forming said symmetrical heads, each sub-island being delimited by a respective closed peripheral line all the points of which being in contact with said sub island.

A laminate comprising a support component in the form of a first web of fibres and/or filaments, and a component with loops in the form of a second web of fibres and/or filaments, the two components being fixed to one another, wherein the fixing causes so-called calendering islands to appear on the exterior surface of the component with loops in the shape of an S with two symmetrical heads, characterised in that each S-shaped island with two symmetrical heads comprises two sub-islands forming said symmetrical heads and an intermediate, non-fixed region separating the two sub-islands forming said symmetrical heads, each sub-island being delimited by a respective closed peripheral line all the points of which being in contact with said sub island, a shortest distance between the two sub-islands being smaller than a largest distance to be measured between any two points of each of said closed peripheral lines.
