Abstract
Touch fastener products, as well as apparatus and methods for manufacturing such products, are described. The methods and apparatus feature certain mold cavity shapes that are designed to facilitate demolding of hammer hook touch fastener elements exhibiting desirable fastening properties. Such mold cavity shapes can be combined with particularly soft molding resins to produce useful fastening products.
