Abstract: Rigid substrates having molded fastener projections, and methods of making the same are disclosed. A substrate has a beam stiffness, measured as a product of an overall moment of inertia of a nominal transverse cross-section and an effective modulus of elasticity of a material from which the substrate is made, that is greater than about 200 lb-in2 (0.574 N-m2). In situ lamination of hook, bands or islands on surfaces of a rigid substrate held in a planar orientation or presenting a planar surface.

Abstract: Fastenings, including stretchy or flexible “zebra-like” and “leopard-like” appearing materials, are disclosed having spaced bands or a distribution islands of molded loop-engageable hooks or molded pre-forms for hooks, between which are bands or regions of different character. Molding is by rigid molds filled from the base region of the stems. In embodiments, linear bands or islands of fastener elements are themselves inextensible in the direction of their extent and comprise multiple rows of fastener elements. For ease of forming a uniform, elastically stretchy or flexible product, the bands or islands of fastener elements extend in the machine direction during manufacture.
