Abstract
An apparatus for joining two elements of a fastener element together with a sheet of compliant material sandwiched therebetween includes an apertured member whose opening is shaped to accept one of the fastener elements. The remote end of the fastener element has a recess therein with the material stretched taut across the opening to the recess. A prong member pierces the material and seats itself in the recess with the material immediately surrounding the recess lying in a wrinkle free condition.
