Patent number: 6711858Abstract: Pile weatherstripping is provided by a flat pile of strands which are tensioned to spring outwardly to straight condition to provide a pile weatherstrip, when bent and inserted into a T-slot or other kerf in a member such as a window or door frame or sash. The tendency of the bent parts of the pile to spring away from each other facilitates retention of the pile after insertion into the slot. A locking fin, more rigid than the pile, is preferably used. This locking fin engages steps or edges in the throat of the slot thereby impeding withdrawal of the weatherstripping from the slot. One or more barrier fins may also be assembled with the strands constituting the flat pile. The pile can be operated in bending mode or in columnar compression (crushing mode). Bending mode operation can be over a bending range so as to accommodate a large range of clearance between a sash and a frame or other members which are sealed by the pile weatherstripping.Type: GrantFiled: September 7, 2000Date of Patent: March 30, 2004Assignee: Ultrafab, Inc.Inventors: James V. Albanese, David N. Hawkins

Patent number: 6670018Abstract: A net fabric to be processed into a net product capable of simplifying processing during manufacturing of a net product, leading to a reduction in manufacturing cost of the net product is disclosed. The net fabric is so constructed that the side edge portions of the net fabric, which are subjected to processing such as cutting, vibrational welding or the like, have a higher compressibility in the thickness direction than the middle portions of the net fabric. This ensures that the net fabric exhibits a better workability during the manufacturing of the net product using the net fabric in order to simplify the manufacturing process, and to lead to a reduction in manufacturing cost, even though the net fabric has a three-dimensional structure.Type: GrantFiled: May 22, 2001Date of Patent: December 30, 2003Assignees: Delta Tooling Co., Ltd., Suminoe Textile Co., Ltd.Inventors: Etsunori Fujita, Yumi Ogura, Masaki Nishino, Eiichi Koyama, Yoshio Tsumura, Kazuhiro Ueda
