The invention relates to a method for producing a gasket on a component using a shaping tool, wherein the material used for the gasket is a UV-curable sealing or gasket material, and wherein the shaping tool comprises an upper face and a lower face and at least one cavity which is open toward the lower face of the shaping tool and which is provided for filling with the gasket material, and wherein furthermore the shaping tool is made of a UV-transparent material at least in the region of the cavity, comprising the following steps in the order indicated: 1. introducing the gasket material into the cavity of the shaping tool; 2. placing the component onto the lower face of the tool provided with the gasket material; 3. pressing the component onto the tool; 4. curing the gasket material by way of UV irradiation; and 5. removing the tool from the component and the gasket joined thereto. The invention further relates to a shaping tool for use in such a method.

A molding apparatus includes an extrusion die having an extruding orifice and a projection forming orifice, and a rotor rotatably installed in a middle portion of the extrusion die and having a forming recess adjacent to the projection forming orifice.

An apparatus for making hollow, form-in-place gaskets is disclosed. The apparatus includes a nozzle and a forming surface. The nozzle comprises an extrusion orifice for extruding a gasket onto the forming surface. The apparatus further includes means for the nozzle to separately communicate with an air supply and a liquid elastomer supply. The nozzle configuration maintains the separation between the supplied air and the supplied liquid elastomer proximate to the extrusion orifice.

A foam twin-sheet formed air filled gasket is provided. The foam sheets need not be covered with one or more layers of air impermeable materials before, during or after the twin-sheet forming process. Methods for manufacturing the air filled gaskets are also disclosed.

The object of the present invention is to provide a gasket forming mold with a structure in which curling of the reversing section of the gasket molding does not occur easily. To achieve said object, the forming mold for integrally forming an endless shaped gasket has forming grooves as cavities in the parting surfaces of the forming mold and the forming grooves have a reversing section in a part thereof. The reversing section has two linear portions and the ends of the two linear portions are connected by an arc-shaped curved section. The two linear portions are arranged at literally-symmetrical positions and are arranged so that a distance therebetween is enlarged little by little from one end toward the other. The ends where said distance is enlarged are connected by the circular arc-shaped curved section.

An apparatus for detecting a weather strip seam includes a sensing roller connected to one surface of a weather strip and rotating along with movement of the weather strip, a load cell unit sensing a signal corresponding to force transmitted to the sensing roller in the weather strip, and a controller that senses a seam formed in the weather strip using the signal sensed by the load cell unit.

An assembly for use on an aircraft wing having an aircraft skin and a fuel tank, the assembly comprising a metal access door for accessing the fuel tank, a metal retainer ring for engaging the wing and the access door. Fasteners removably couple the access door to the retainer ring. A lip, which may be on the wing surface, is configured to receive a perimeter of the access door when the access door is coupled to the retainer ring. A polyurethane elastomeric gel gasket having a metallic skeleton is configured to lay between the access door and a lip of the metal wing surface. Under compression, the polyurethane will deform and squeeze out the edges and flatten so as to provide metal-to-metal contact between the access door and the lip.

The weather strip configured to be attached to the automobile body opening portion is an elongated member having a length configured to correspond to a side portion and a corner portion of the automobile body opening portion and includes a hollow sealing portion. A surface of the sealing portion corresponding to a floor-side side portion and a surface of the sealing portion corresponding to a floor-side corner portion are continuous to each other. A wall thickness of the sealing portion corresponding to the floor-side side portion is set to be smaller than a wall thickness of the sealing portion corresponding to the floor-side corner portion. The sealing portion corresponding to the floor-side side portion includes a portion having a smallest wall thickness among the entire sealing portion.

A laminated gasket (13) to be used for a medical syringe is provided, which includes a main body (14) made of an elastic material, and a film (15) provided on a surface of the main body (14). The gasket (13) has a circumferential surface portion (17) to be brought into contact with an inner peripheral surface (16) of a syringe barrel (11) of the syringe. The gasket (13) further includes a projection (22) provided on a surface portion of the film (15) present in the circumferential surface portion (17) as extending circumferentially of the gasket. The projection (22) has a height of not less than 15 m and not greater than 55 m and a width of not less than 30 m and not greater than 75 m. With this arrangement, the laminated gasket is excellent in sealability.

An apparatus suitable for extruding curable polymers for forming elastomer articles using additive manufacturing, and curable fluorine-containing polymer compositions suitable for use in such an apparatus are disclosed along with an additive manufacturing method for forming a fluorine-containing elastomer including providing a curable fluoropolymer composition, comprising at least one curable fluoropolymer; providing an additive manufacturing printer apparatus comprising a ram material extruder, wherein the ram material extruder comprises a ram device operable for extrusion under pressure and a printer nozzle; introducing the curable fluoropolymer composition to the ram material extruder; applying heat to the ram device, including the printer nozzle thereof; and applying pressure to the ram device to extrude the curable fluoropolymer composition; and printing, using the additive manufacturing printer apparatus, at least one layer of the extruded curable fluoropolymer composition exiting from an outlet of the printer nozzle onto a substrate to form the fluorine-containing elastomer article.
