Patent number: 11964821Abstract: Apparatus comprising a process belt includes a woven rectangular planar structure with opposed longitudinal ends that are joined together to form an endless belt. The exemplary woven planar structure includes metal and glass warp fibers that extend in the longitudinal direction, and metal and/or glass weft fibers which extend transversely of the warp fibers. The diameter of the glass warp fibers is substantially greater than the diameter of the metal warp fibers which causes the outer surfaces of the glass fibers to extend outwardly of the metal warp fibers on the outer surface. This configuration causes items engaged with the outer surface to be operatively engaged with only the glass warp fibers. In exemplary arrangements a coating comprised of fluoropolymer extends on the fiber surfaces which comprise the entire outer surface of the planar structure and the belt.Type: GrantFiled: March 12, 2021Date of Patent: April 23, 2024Assignee: GKD - Gebr.

Patent number: 7072567Abstract: In order to provide a metal fabric of a design which reduces or even completely compensates for the effect of darkening which is intrinsic to the metal fabric at a predetermined fabric density, a metal fabric having an optical waveguide element penetrating a core fabric area is suggested. In addition, a metal fabric having multiple optical waveguide elements and/or optical waveguide elements integrated structurally into the fabric is suggested. In addition, a method for manufacturing a metal fabric is presented.Type: GrantFiled: June 10, 2004Date of Patent: July 4, 2006Assignee: GKD - Gebr. Kufferath AGInventor: Michael Hammers

Patent number: 6379817Abstract: A metallic fabric for manufacturing a hollow body is welded at two edge areas and according to the present invention a metallic strip is welded on in the vicinity of the welded seam, whereby the width of the welded seam is narrower than the width of the metallic strip. An elastic material which flattens out vibrations of the hollow body and ensures protection of the welded seam is arranged between the metallic strip and the metallic fabric.Type: GrantFiled: August 15, 2000Date of Patent: April 30, 2002Assignee: GKD Gebr, Kufferath GmbH & Co., KGInventor: Ingo Kufferath

Patent number: 5158171Abstract: A woven wire belt for an apparatus in which the belt runs in the direction of its warp wires over rotatable rollers has weft wires which have lower projections which protrude at the lower side of the belt, for lateral guidance of the belt. Upper projections in the weft wires or inserted guide lines protrude beyond the upper side of the belt and serve for the punctiform support of a conveyed product or engage as carriers behind the conveyed product if the latter is conveyed by a belt running obliquely upwards or obliquely downwards.Type: GrantFiled: September 19, 1991Date of Patent: October 27, 1992Assignee: GKD Gebr. KufferathInventor: Wilhelm Graff

Patent number: 4944716Abstract: Wire netting belt, more particularly for conveyors, screen belt presses or the like, which is closed at its belt ends by an insert-type join to constitute an endless belt and is strengthened in its plane in its end regions with reinforcing strips consisting of a solidifying composition, to obviate arching of the belt at its central zone in the end regions.Type: GrantFiled: August 4, 1989Date of Patent: July 31, 1990Assignee: GKD Gebr. Kufferath GmbH & Co. KGInventor: Wilhelm Graff

Patent number: 4318469Abstract: A wire mesh band or belt for a conveyor having downwardly extending protuberances for engaging peripheral grooves in rollers of a conveyor system to maintain the band in proper transverse position. The protuberances are formed on guide wires woven into the band at lateral and longitudinal intervals in the weft direction. The guide wires have at least one flattened surface so that they cannot rotate about their longitudinal axis. In a second embodiment, instead of continuous guide wires, a plurality of guide wire sections may be arranged at intervals transversely across the band.Type: GrantFiled: December 28, 1979Date of Patent: March 9, 1982Assignee: GKD Gebr. Kufferath GmbH & Co. KGInventor: Karl Kufferath-Kassner

Patent number: 4249653Abstract: A wire mesh band or belt with mutually crossing warp wires and weft wires for a conveyor system with grooved support rollers is provided with downwardly extending protrusions. The protrusions are warp wire free providing great flexibility for the band in the longitudinal direction. The protrusions can be formed in all the weft wires or only in selected strengthened weft wires with the remaining weft wires woven into the fabric after the protrusions are formed.Type: GrantFiled: December 28, 1979Date of Patent: February 10, 1981Assignee: GKD Gebr. Kufferath GmbH & Co. KGInventor: Karl Kufferath-Kassner
