  • Patent number: 8658068
    Abstract: A touch fastener including an elongated base having multiple segments connected by articulable joints. Each segment has an upper surface, a lower surface, and a plurality of touch fastener elements extending from the lower surface of the base. A flexible barrier extends across at least one articulable joint between adjacent base segments. The fastener may include a magnetically attractable material disposed along a center region of the upper surface of the base. The fastener base may define a pair of first and second notches in opposite longitudinal edges of the base at the articulable joint to allow bending of the base. The base may also define a slit extending through the base from a longitudinal edge thereof at the articulable joint.
