Forming fastening projections on rigid substrates
First Claim
Patent Images
1. A method of forming fastening projections on a rigid substrate, the method comprising:
- delivering a resin to an outer surface of a rigid substrate;
molding from the resin an array of discrete stems in cavities defined in a peripheral surface of a mold roll rolled over the surface of the substrate, the stems withdrawing from their cavities by continuous rotation of the mold roll while the substrate remains rigid, leaving the stems projecting from the surface of the substrate;
bonding the resin to the outer surface of the substrate; and
forming fastening heads at distal ends of the stems,wherein the substrate comprises one or more members selected from the group consisting of a wallboard, a window frame, a wall panel, a floor tile, and a ceiling tile.

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.

28. A method of forming fastening projections on a rigid substrate, the method comprising:
-
delivering a resin to an outer surface of a rigid substrate; molding from the resin an array of discrete stems in cavities defined in a peripheral surface of a mold roll rolled over the surface of the substrate, the stems withdrawing from their cavities by continuous rotation of the mold roll while the substrate remains rigid, leaving the stems projecting from the surface of the substrate; bonding the resin to the outer surface of the substrate; and forming fastening heads at distal ends of the stems, wherein the resin is delivered directly into the cavities in the mold roll and the resin is then bonded to the substrate, and wherein the discrete projections are individually bonded to the surface of the substrate without any additional resin bonded between the projections to the surface of the substrate.
