Patent number: 10577744Abstract: A fabric is treated by applying a nanoparticle type coating to improve their resistance to contamination by foreign matter. The coating is applied during fabric manufacture and cured during heat setting. Alternatively, the coating applied or renewed by utilizing an existing shower or locating a spray boom or other suitable coating application device to apply the coating to the fabric in a controlled, uniform manner. Prior to application of the coating, the fabric is first thoroughly cleaned such as by showering or spraying, and then dried. Following controlled application of the coating, any excess material is removed by a suitable means, such as by vacuum, and the remaining coating on the fabric is then cured, either by utilizing the ambient heat of the equipment or by a portable bank of heaters. In this manner, the fabric does not have to be removed from the machine in order to apply or renew the contaminant resistant coating.Type: GrantFiled: February 6, 2017Date of Patent: March 3, 2020Assignee: AstenJohnson, Inc.Inventors: Samuel M. Baker, Rex Barrett, Bud J. Chase, Bruce W. Janda, Ian Gerald Lang, Dietmar Wirtz, Larry Anderson

Publication number: 20030190451Abstract: An industrial fabric comprising at least two separate continuous layers. Each layer includes at least one segment (1) fabricated as a plastics extrusion, such as a strip or panel. The layers are joined by means of cooperating linear interlocking structures (10) located on contiguous planar faces of the segments in the layers. After engagement to form a joint, the cooperating linear interlocking structures provide and maintain a void volume (30) between the layers, and resist compressive loading of the fabric in a more or less predictable manner. The segments may be fabricated from differing thermoplastics so as to impart differing physical properties to each layer. The segments may be porous or non-porous. The industrial fabrics are suitable for use in filtration, membrane, geotechnical and like applications, and find particular utility in continuous filtration applications such as pulp and paper making, sludge dewatering and the like.Type: ApplicationFiled: December 20, 2002Publication date: October 9, 2003Inventors: Samuel M. Baker, Graham V. Jackson

Patent number: 6462145Abstract: A polymer blend consisting essentially of 80% to 95% by weight, based on the total weight of the composition, of polytrimethylene terephthalate and from 5% to 20% of an elastomeric polyester. Fibers and extrusions produced from the polymer blend are durable under repetitive compressive stresses, exhibit mechanical properties comparable to neat polyamide-6, and provide moisture stability similar to yarns and extrusions comprised of polyamide-6/10 or polyamide-6/12. These fabrics find use as forming fabrics, and press felt fabrics for paper making machines.Type: GrantFiled: July 20, 2000Date of Patent: October 8, 2002Inventors: Paul C. Fleri, Samuel M. Baker

Patent number: 6124015Abstract: A substantially planar jointed multi-layer industrial fabric, assembled from at least one segment comprising at least one woven or nonwoven ply, in which the joints utilize jointing yarns or formed structures. The jointing yarns or formed structures are placed at selected locations, such as the lateral edges, of at least one planar surface of a ply of the at least one, or first, fabric segment, and interlock in mating engagement with corresponding jointing yarns or formed structures either in at least one surface of a ply of a second segment, or in another location on the first fabric segment, to provide an integral joint. The joints are comprised of shaped yarns and formed structures which in any combination form mating engagements substantially within the plane of the fabric, such as in hook-and-loop or slot-and-rib type joints, and the like.Type: GrantFiled: April 9, 1997Date of Patent: September 26, 2000Assignee: JWI Ltd.Inventors: Samuel M. Baker, Eugene Fekete, Rajat K. Chakravarty

Patent number: 6030908Abstract: A multilayer porous fabric which comprises a porous core fabric provided with hook means, and at least one layer of pre-needled nonwoven fibrous batt attached by entanglement onto the hook means by pressing the core fabric and batt together. The entanglement is sufficient to anchor the batt reliably to the core fabric, so that the multilayer fabric is ready for use without further processing. The porous core fabric may be formed by weaving or as an extruded sheet, with a plurality of suitably located hook means structures on at least one of its surfaces. The hook structures engage with and entangle sufficient fibers from the pre-needled nonwoven batt to provide adequate attachment preventing the batt from separating from the core fabric enabling the multilayer fabric to be handled before use, for example for installation in a papermaking machine press section. The batt is pre-needled to a desired density before attachment to the core fabric.Type: GrantFiled: March 16, 1998Date of Patent: February 29, 2000Assignee: JWI Ltd.Inventors: Samuel M. Baker, Eugene Z. Fekete, Graham W. Jackson, Kurt Wiebe

Patent number: 5819811Abstract: A flat woven, pin seamed, papermakers' fabric, comprising primary warp monofilament yarns, primary weft monofilament yarns and secondary weft monofilament yarns located between and adjacent to the primary weft yarns. The secondary weft yarns are located beneath, and in contact with, the primary warp. The thickness and width of the secondary weft yarns are chosen at the weaving stage so as to control finished fabric air permeability and increase the paper side surface contact area. The fabrics are of a lower caliper, and provide increased cross direction stiffness at lower yarn counts. Formation of the pintle receiving loop yarns in a low marking woven back pin seam, or of a streamline seam, is also facilitated, without compromising fabric properties, by selection of the appropriate dimensions of the secondary weft yarns.Type: GrantFiled: April 25, 1997Date of Patent: October 13, 1998Assignee: JWI Ltd.Inventors: Samuel M. Baker, Marc P. Despault, James D. Harrison
