Patent number: 9381712Abstract: A system and method are presented in which a flow of plastic is extruded to obtain nano-sized features by forming multiple laminated flow streams, flowing in parallel through the non-rotating extrusion system. Each of the parallel laminated flow streams are subjected to repeated steps in which the flows are compressed, divided, and overlapped to amplify the number of laminations. The parallel amplified laminated flows are rejoined to form a combined laminated output with nano-sized features. The die exit is formed to provide a tubular shape.Type: GrantFiled: December 23, 2011Date of Patent: July 5, 2016Assignee: Guill Tool & Engineering Co., Inc.Inventors: Richard Roy Guillemette, Robert G. Peters, Christopher J. Hummel

Patent number: 9056406Abstract: A method for the creation of a plurality of continuously folded layers. This approach for creating multilayered products begins with a typical flow channel for a product in which the cross-section of this flow channel is an annular ring. The flow channel is then morphed to create folds in the flow channel. Fold patterns are manufactured into the channel walls so as to gradually modify the contour of the stream. These folds are oriented and propagated in such a way so that the flow can be converged back to a flow passage with a typical cross section but now with a multiplied number of layers. This process may be repeated to multiply the number of layers. The number of folded layers can include 3-10 layers, ten to hundreds of layers and ten to thousands of layers. The layers remain continuous around the product.Type: GrantFiled: November 19, 2013Date of Patent: June 16, 2015Assignee: Guill Tool & Engineering Co., Inc.Inventor: Robert Peters

Publication number: 20130344271Abstract: A multi-layer extrusion die assembly includes a body, a main bore extending longitudinally through the assembly, a core tube, and a plurality of dies. The extrusion die assembly is configured to receive an input stream of material and divide the input stream into a plurality of material streams. Each die is configured to receive one or more of the material streams and to form a single continuous layer of material about the core tube. The layer formed by each die has one or more weld lines running longitudinally along the layer. The dies are arranged along the core tube such that a plurality of concentric layers of material is formed around the core tube. Each die is rotated axially with respect to adjacent dies such that the weld lines of the layer formed by one die.Type: ApplicationFiled: April 26, 2013Publication date: December 26, 2013Applicant: GUILL TOOL and ENGINEERING Co., Inc.Inventor: Roger GUILLEMETTE
