Patent number: 11214039Abstract: A process for producing a textured laminate sheet includes a) positioning a substrate material adjacent a barbed face of a metal sheet. The barbed face has a plurality of barbs, and the metal sheet has an opposed face opposite the barbed face. The process further includes b) forcing the metal sheet and the substrate material together to impale the substrate material on the barbs and secure the substrate material and the metal sheet together as a laminate sheet, and c) debossing the opposed face to form a plurality of depressions in the laminate sheet and texture the laminate sheet.Type: GrantFiled: April 26, 2019Date of Patent: January 4, 2022Assignee: GRIPMETAL LIMITEDInventor: Ray Arbesman

Patent number: 11198170Abstract: A material including a metal sheet, a first plurality of raised and pointed structures, and a second plurality of raised and pointed structures is provided. The metal sheet includes first and second opposed sides, and a thickness between the first and second opposed sides. The first plurality of raised and pointed structures are gouged out of the first side of the metal sheet. The sheet is not perforated, and the raised and pointed structures of the first plurality have a height of between 150% and 300% of the thickness. The second plurality of raised and pointed structures are gouged out of the second side of the metal sheet.Type: GrantFiled: May 13, 2019Date of Patent: December 14, 2021Assignee: Gripmetal LimitedInventors: Ray Arbesman, Nghi Pham, Winston MacKelvie

Patent number: 11059267Abstract: The present invention is a laminate sheet having two laminae. The first lamina is a relatively hard material having first and second surfaces. The first surface has a plurality of raised and generally pointed piercing structures, each structure having a tip. The second lamina is graphite foil material, which is mated to the relatively hard material, such that at least some of the piercing structures pierce the graphite foil material. In one embodiment, the first lamina has no performations and is uniformly smooth. In another embodiment, the second surface also has a plurality of piercing structures and a third lamina comprising graphite foil is mated to the second surface.Type: GrantFiled: June 18, 2018Date of Patent: July 13, 2021Assignee: Gripmetal LimitedInventor: Ray Arbesman

Patent number: 11045860Abstract: A material includes a sheet of metal having a first face and an opposed second face, and a metal grain direction. The first face is textured with a first set of texturing features. Each texturing feature of the first set includes, respectively, a groove cut into the first face and extending along a groove axis, and a barb extending from the groove and away from the first face. The texturing features of the first set are arranged in a plurality of rows, and the groove axes of the texturing features in a given row extend generally parallel to the given row. The rows are generally non-perpendicular to the grain direction.Type: GrantFiled: May 31, 2018Date of Patent: June 29, 2021Assignee: GRIPMETAL LIMITEDInventor: Ray Arbesman
