Structured Surface Hook Caps for Peel Strength

The patent changes the geometric parameters of the hook elements by modifying the orientation of distal caps through mechanical deformation. Implements are passed between adjacent rows to turn overhanging portions of distal caps, changing their spatial configuration from extending outward to turning downward or sideways. This parameter change in cap orientation directly increases peel strength while maintaining attachment reliability

The patent creates asymmetric hook elements by selectively orienting distal caps in different directions. Rather than uniform symmetric caps, the implementation process creates caps that extend in varied orientations, with some turning downward and others maintaining original extension. This asymmetric configuration enhances interlocking with loop materials, improving both peel strength and overall attachment performance

The patent employs self-service by using the implements to simultaneously perform multiple functions: they guide, deform, and orient the distal caps in a single pass. The implements are designed to automatically engage with the overhanging portions and turn them in the desired direction without requiring separate positioning or fixing steps. This self-service approach simplifies the overall process despite the complexity of shape modification

The patent applies preliminary action by pre-configuring the implements with specific geometries that match the desired final shape of the distal caps. The implements are designed beforehand to perform the deformation action in a single pass, eliminating the need for multiple subsequent shaping operations. This preliminary design of the implements reduces overall process complexity while achieving the desired cap orientation
