Abstract
The subject matter of this invention relates to a method of making glass fiber mat reinforcement material with a thermoplastic adhesive powder. Fiberglass strands are chopped and randomly air dropped onto a Teflon.RTM. coated conveyor belt to form a loose mat. A water mist is then applied to the loose mat and transport belt, before a powdered adhesive is dispensed. Heat is applied to plasticize the adhesive and finally the adhesive is solidified by cooling. The adhesive will then release from the transport belt and is adhered to the material forming the fiberglass reinforcement mat.
