Patent number: 8801880Abstract: The invention relates to ultrasonic gap welding of flat woven fabrics. Specifically, the invention relates to a method of ultrasonic welding the seam termination yarn ends of a fabric using a controlled gap. A mechanical stop may be employed to control the distance or gap between the horn and anvil to a predetermined level based on the depth of welding and amount of weld energy. By adding another degree of control, the ultrasonic gap welding technique of the present invention is able to achieve fabric seams that are stronger than conventional seams, and even those enhanced with gluing, and is conducive to formation of fabric seams by spot welding or along the termination yarn ends of the fabric.Type: GrantFiled: August 9, 2010Date of Patent: August 12, 2014Assignee: Albany International Corp.Inventors: John J LaFond, Jennifer L Bowden, Lynn F Kroll, Joseph Botelho

Patent number: 8202396Abstract: A clothing for structuring a wet fibre web (1?) in a press section of a tissue papermaking machine is described which has a three-dimensional woven structure forming elevations (62) and depressions (63), said elevations, like the depressions, are repeated and distributed to form a pattern of polygonal, geometrically similar smallest unitary surfaces (64), each of said unitary surfaces having an area a and covering a plurality of depressions with the mean depth d. According to the invention, the area a and the mean depth d of each unitary surface (64) are adapted in relation to each other in such a way that, calculated by the length unit mm, their ratio is equal to or greater than 30 mm, wherein a is selected within the range of 1.0-3.0 mm2 and d is selected within the range of 0.03-0.09 mm. The invention also relates to a method for manufacturing a creped tissue paper web by using said structuring clothing.Type: GrantFiled: November 14, 2008Date of Patent: June 19, 2012Assignee: Albany International Corp.Inventors: Magnus Hultcrantz, Ingvar Klerelid, Bo-Christer Aberg, Cary P.

Patent number: 7300554Abstract: A multi-layer tissue forming fabric constructed so that the top forming surface has topographical differences measured as a plane difference between at least two top weft yarns. The plane difference—the difference in height between the two weft yarns—must be greater than zero. Using at least two different diameter, size, or shape weft yarns positioned at the same contour in the forming surface creates this plane difference and defines pocket areas in the forming surface of the tissue forming fabric. The pocket areas act to generate bulk, cross directional tensile, absorbency, and softness in a formed sheet of tissue, napkin, or towel paper.Type: GrantFiled: September 11, 2003Date of Patent: November 27, 2007Assignee: Albany International Corp.Inventors: John J.
