Publication number: 20010008676Abstract: Elongated apertures each having a major axis and a minor axis, are formed in a stretchable film having a predefined direction of stretch. The apertures are oriented in the film with the major axes of the apertures disposed perpendicular to the predefined direction of stretch. The apertures are also disposed in the film with greater separation between the apertures in the direction parallel to the major axes of the apertures than the separation between adjacently disposed apertures in a direction parallel to the minor axes of the apertures. The elongated openings, when positioned with the major axes perpendicular to a predefined direction of stretch, has better breathability and elastic properties than comparable symmetric aperture shapes when both are subjected to cross direction elongation.Type: ApplicationFiled: June 24, 1998Publication date: July 19, 2001Inventors: JAMES E. PELKIE, GREGORY M. RIEKER

Patent number: 5945196Abstract: A method for the manufacture of a screen useful for forming three-dimensional films, the screens and the three-dimensional films produced using those screens are disclosed. In forming a screen, a substrate material is applied to a base. A predetermined amount of portions of the substrate are removed to form a predetermined pattern in the substrate. A screen material is applied to the patterned substrate material. A predetermined amount of portions of the screen material are removed to form a predetermined pattern in the screen material. The predetermined pattern in the screen defines a plurality of first perforations in the screen material. The substrate material is removed from the screen material, such that second perforations are formed in the screen, whereby each first perforation is in communication with an adjacent second perforation.Type: GrantFiled: January 30, 1997Date of Patent: August 31, 1999Assignee: Tredegar Industries, Inc.Inventors: Gregory M. Rieker, Edward R. Cook

Patent number: 5718928Abstract: A cylindrical screen for perforating a thermoplastic film or sheets has an outer surface and an inner surface. A plurality of outer apertures extend from the outer surface and terminate at a corresponding inner aperture on the inner surface of the screen. The apertures in the outer surface can have the same or a different geometrical shape as the apertures in the inner surface. The apertures form a passageway through the screen. The passageways are disposed at least one angle from about 5.degree. to about 60.degree. with respect to a plane that is disposed substantially perpendicular to the outer surface of the screen to prevent a direct line of sight through the screen.Type: GrantFiled: June 14, 1996Date of Patent: February 17, 1998Assignee: Tredegar Industries, Inc.Inventor: Gregory M. Rieker

Patent number: 5591510Abstract: The invention is directed to a layered fabric material that is breathable and has resistance to fluid penetration. The fabric has a lightweight, breathable outer layer and a layer of non-woven material. The non-woven material is breathable and fluid resistant. The fabric also includes a thermoplastic film having a plurality of perforations. The perforations form capillaries that extend from a surface of said film. The capillaries are disposed at an angle from about 5.degree. to about 60.degree. with respect to the surface of said film. The capillaries formed by the perforations allow the film layer to be breathable while resisting direct flow of liquid through the film.Type: GrantFiled: June 14, 1994Date of Patent: January 7, 1997Assignee: Tredegar Industries, Inc.Inventors: Stephen G. Junker, Gregory M. Rieker, Paul E. Thomas

Patent number: 5562932Abstract: A cylindrical screen for perforating a thermoplastic film or sheets. The screen is formed from a relatively thin sheet that is secured together to form a cylindrical shape. A plurality of apertures are positioned in the sheet and the apertures in the sheets forms a passageway through the screen. The passageways are disposed at an angle from about 5.degree. to about 60.degree. with respect to a plane that is disposed substantially perpendicular to the surface of the screen.Type: GrantFiled: June 14, 1994Date of Patent: October 8, 1996Assignee: Tredegar Industries, Inc.Inventor: Gregory M. Rieker
