Abstract
An extruded-in fabric hinge comprised of a fabric hinge member extruded-in with a first member and a second member such that at least some of the fibers of the fabric hinge member are embedded within the first and second members. An extruder apparatus with an extrusion cavity comprised of a first surface with a first adjustable mandrel, a second surface, a third surface, and a fourth surface integrated to form the extrusion cavity is used to make the extruded-in fabric hinge. A fabric hinge member is captured between the first adjustable mandrel and the second surface, and an extrusion material is extruded through an extrusion inlet of the extruder apparatus and into the extrusion cavity. The extrusion material integrates with the fabric hinge member such that at least some of the fibers of the fabric hinge member are embedded into the first and second members of the extruded-in fabric hinge.
