Abstract
A separable fastener component for use with a complementary separable fastener component has a base member, having a nominal fastening face and a non-fastening face. Carried on the fastening face is a pattern of fastening elements, comprising a main region carrying fastening elements. Substantially surrounding the main region is a bald region that is substantially free of fastening elements; and substantially surrounding the bald region, is a perimeter region that carries fastening elements. The bald region may be a rectangular annulus, as may be the perimeter region of fastening elements. The bald and perimeter regions may also be non-rectangular. The sacrificial perimeter fastening elements may be hooks or loops. Anchoring elements may be provided on the non-fastening face of the base. Rather than the bald region being one that surrounds the main region, it may bound a portion of the main region and may be a pair of bald regions that are substantially free of fastening elements. Adjoining each of the bald regions is a bounding region that carries hook-type fastening elements, arranged such that each bald region is sandwiched between said main region and a respective bounding regi…
