Publication number: 20100253013Abstract: The present invention relates to a co-extruded sealing strip for a motor vehicle or building which is reinforced by at least one plastic carrier, to a method for manufacturing such a strip and to a device for implementing this method. This sealing strip includes at least one extruded reinforcing plastic carrier around which a flexible polymeric cover is co-extruded and which forms at least one continuous line having undulations extending lengthwise with a variable pattern, such as a variable undulations period, so as to locally impart a variable flexibility or compressibility thereto.Type: ApplicationFiled: March 30, 2010Publication date: October 7, 2010Inventor: Morgan Mills

Publication number: 20100221064Abstract: A joint comprising: a first component having a face and a bore defined by a bore wall; a second component; a fastener joining the first component to the second component, the fastener comprising a head and a shaft protruding from the head; and a polysulphide gasket comprising a ring which is compressed between the head of the fastener and the face of the first component; and a collar between the shaft of the fastener and the bore wall. The gasket comprises a ring of sealing material surrounding a hole for receiving a fastener, the sealing material comprising an at least partially cured polysulphide sealant. The gasket has a region of increased thickness positioned towards the inner periphery of the ring which flows to form the collar.Type: ApplicationFiled: October 20, 2008Publication date: September 2, 2010Applicant: AIRBUS UK LIMITEDInventors: Colin John West, David Alistair Sutton

Publication number: 20100150724Abstract: An elastomer material seal for an interleaved platform between two adjacent blades in a turbomachine rotor is disclosed. The seal is of elongate shape and includes transversely a contact part, an attachment part, and a flexible part between the attachment part and the contact part. The seal is noteworthy in that it further includes a local reinforcement of the flexible part, to avoid the tearing that would result from centrifugal forces on the seal. The local reinforcement of the flexible part includes at least one transverse rib on the flexible part.Type: ApplicationFiled: December 11, 2009Publication date: June 17, 2010Applicant: SNECMAInventors: Jean-Bernard FORGUE, Patrick Jean-Louis REGHEZZA, Carole STOCHMIL
