Abstract
A hook-type fastener product for engaging loop elements is disclosed, having parallel rows of hooks having differently constructed first and second sides. The hooks are arranged such that, when engaged with loops, they resist disengagement from the loops more strongly when pulled in one sideways direction than when pulled in the opposite sideways direction. The product has a common base from which the hooks, which are not limited to J-type hooks, extend. The first sides of the hooks may be flat and the second sides convex. Methods and an apparatus for producing the product are also disclosed.
