Patent number: 8562885Abstract: Disclosed are multilayer film structures having annular profiles, and methods and apparatus of making the structures disclosed. The annular multilayer articles have a uniform thickness, at least four layers and comprise overlapped and non-overlapped circumferential areas; wherein the layer structure of the non-overlapped area is doubled in the overlapped layer. A method of making the structure includes providing a multilayer flow stream with at least four layers of thermoplastic resinous materials; feeding the multilayer flow stream to a distribution manifold of an annular die to form an annular multilayer flow stream; and removing the annular multilayer flow stream from the annular die to form the annular multilayer structure.Type: GrantFiled: February 16, 2010Date of Patent: October 22, 2013Assignee: Dow Global Technologies Inc.Inventors: Joseph Dooley, Jeffrey M.

Patent number: 8496460Abstract: A method and apparatus is provided for distributing material through a multilayer pipe extrusion die. A first flow passageway, having a first cross-sectional area and extending along a first flow direction, may be connected to a second flow passageway, having a second cross-sectional area substantially the same as the first cross-sectional area of the first flow passageway, to provide a second flow direction different from the first flow direction of the first flow passageway. A conical passageway may extend from the second passageway toward a dispensing outlet. Material may be distributed from the first flow passageway into the second flow passageway. The method and apparatus may generally maintain the same flow properties of the material at a point before and after the connection of the first flow passageway and the second flow passageway. The flow properties of the material may be altered proximate to the outlet.Type: GrantFiled: February 25, 2008Date of Patent: July 30, 2013Assignee: Advanced Drainage Systems, Inc.Inventor: Gerald S. Sutton

Patent number: 8465272Abstract: Apparatus and methods for fabricating food items include extruding a first hot plastic food mass through multiple passages (14) and co-extruding a second hot plastic food mass through a feed stem (22) received in each of the multiple passages (14) and through nozzles (42). Each nozzle (42) includes a first portion (42b) in communication with the feed stem (22) but not the passage (14) and a second portion (42a) in communication with the passage (16) but not the feed stem (22). The nozzles (42) are rotatable in gearing relation with the drive gear (70) of a servomotor (72). The co-extruded ropes are conveyed at a linear speed rate less than or equal to the discharge speed from the nozzles (42), cooled, and cut into individual pieces in the form of peelably separable strands.Type: GrantFiled: September 28, 2007Date of Patent: June 18, 2013Assignee: General Mills, Inc.Inventors: James N. Weinstein, James M. Olive, Peter A. Huberg, Laurie Burgess, Thomas Leuhrs, Jennifer M. Mcaab

Patent number: 8398908Abstract: A method for the production of a plastics pipe (9) comprising an inner core and an outer removable skin bonded thereto, which method comprises co-extruding molten polymeric materials forming the inner core and the outer removable skin layer from one or more extruder dies, bringing the polymeric materials together and allowing them to solidify, and conditioning the solidified polymeric materials at a temperature and for a time sufficient to influence the adhesion of the outer skin layer to the inner core, such that on cooling the adhesion of the outer skin layer to the inner core is sufficient to prevent substantial undesired relative movement between the skin layer and the core during installation of the pipe (9), but insufficient to prevent the outer skin layer from being clearly removed by peeling, at least at the ends of the pipe (9), and insufficient to cause a substantial reduction in the impact strength of the inner core.Type: GrantFiled: December 23, 2005Date of Patent: March 19, 2013Assignee: Radius Systems LimitedInventor: Lawrence Richards
