Abstract
A method is provided for triple extrusion of a foam material, a coating and one or more flexible flanges attached to the coating or foam material. All three materials are coextruded through a common die and are useful for forming window sashes.
Claims15
A method of forming a solid, elongated frame member of predetermined profile having a coating on at least a portion of the surface of said member and at least one flange attached to said member, said flange being of a flexible material, comprising the steps of:
- compressing an extrudable foam material at a compression stage by passage through an orifice, said orifice having at one end thereof said predetermined profile;
- applying to at least one surface of said foam material at a coating stage within said orifice subsequent to said compression stage, a fluid coating material;
- applying to said foam material at a flange-forming stage within said orifice a flexible material in fluid form whereby said flexible material is extruded through at least one slot in said orifice to form a flange, one edge of which is in contact with said foam material, thereby forming said member;
- withdrawing said member from said orifice and setting said foam material, coating material and flexible material whereby said coating solidifies and is securely bonded to said foam material and said flexible material solidifies to a flexible flange forming a part of said member.
