Patent number: 8172171Abstract: An adjustable doff core device for installation in the hollow center of a center-pull doff has a tubular core with a fixed internal diameter configured for engagement on a processor configured to dispense material from the outside of a doff. An adjustable outer press bar portion is adjustably mounted on the outside of the tubular core by an adjustment mechanism and is movable between an inner, contracted position and outwardly expanded positions spaced outwardly from the tubular core to define an adjustable outer diameter of the device. The press bar portion is configured for substantially non-slip engagement with an inner diameter of a hollow center-pull doff. A locking device releasably locks the press bar portion in a selected adjusted position.Type: GrantFiled: January 5, 2011Date of Patent: May 8, 2012Assignee: Ebert Composites CorporationInventors: David W. Johnson, Scott G. Moyers, James M. Hook

Patent number: 7846528Abstract: A method and apparatus for forming an improved pultruded and clinched Z-axis fiber reinforced composite laminate structure. The upper and lower skins and the core are pulled automatically through tooling where the skin material is wetted-out with resin and the entire composite laminate is preformed in nearly its final thickness. The preformed composite laminate continues to be pulled into an automatic 3-dimensional Z-axis fiber deposition machine that deposits “groupings of fiber filaments” at multiple locations normal to the plane of the composite laminate structure and cuts each individual grouping such that an extension of each “grouping of fiber filaments” remains above the upper skin and below the lower skin. The preformed composite laminate then continues to be pulled into a secondary wet-out station.Type: GrantFiled: May 7, 2007Date of Patent: December 7, 2010Assignee: Ebert Composites CorporationInventors: David W. Johnson, Scott A. Garrett, Stephen G. Moyers, James M. Hook

Publication number: 20090071594Abstract: A method of inserting z-axis reinforcing fibers into a multi-layer composite laminate. Layers of material made up of z-axis fiber and y-axis fibers are automatically transported into a z-fiber deposition machine having a housing with upper and lower surfaces. Z-axis apertures are formed in the respective upper and lower surfaces. An elongated solid rod having a tapered front tip is aligned in close proximity to the aperture in the bottom surface. The rod is first rotated by a motor and then actuated upwardly completely through the thickness of the layer of x-y material by an actuator. A first hollow tube having a z-axis is axially aligned with the aperture in the top surface and a fiber bundle is threaded downwardly through a first hollow tube to a position adjacent its bottom end.Type: ApplicationFiled: June 16, 2008Publication date: March 19, 2009Applicant: EBERT COMPOSITES CORPORATIONInventors: David W.
