Abstract:
A method for continuously molding fastener elements integral with a base web from a flowable resin, the method comprisingproviding a cylindrical mold roll rotatable about an axis of rotation and defining an array of fastener element-shaped mold cavities in a peripheral surface thereof; and applying operating pressure to force resin into said cavities at a mold gap defined adjacent the peripheral surface of the mold roll, to form said fastener elements, while supporting the mold roll with a support member on the side of said mold roll generally opposite the mold gap, the support member arranged to apply a force to the mold roll along its peripheral surface for resisting radial deflection of the mold roll caused by said operating pressure, to maintain the mold gap at a desired thickness profile across the width of the base web under said operating pressure.
