A device producing a weather strip is shown, which includes (a) leading a first uncured pasty material into a certain shaping passage to produce an uncured shaped molded strap; (b) applying continuously a second uncured pasty material onto a given portion of the uncured shaped molded strap while the latter is being moved in the certain shaping passage thereby to produce a layered uncured shaped molded strap; and (c) curing the layered uncured shaped molded strap.

Device for producing weather strip

A structure and process for forming a window guide integrally formed with a window run applicable to an automotive vehicle in which the window guide is formed by means of injection molding with a molten resin. The window guide has an extended portion of a substantially U-shaped cross section, the extended portion may be made uniform in thickness without sinks and/or weld marks by provision of a thickness reducing portion during moulding. An end edge of the extended portion extends toward the outside of the vehicular body.

Structure of window run-integrated guide applicable to an automotive

A weatherstrip system disposed on a body flange of a vehicle at a location facing the door system of the vehicle to establish a seal between the body flange and the door system when the door system is closed comprises a frame member formed of a resin material adapted to clamp the flange of the frame member, an additional layer formed of co-extrudable material laid on a surface of the frame member, and a sealing member joined to the surface of the additional layer for contacting the door system for establishing the sealing between the body flange and the door system. The additional layer is co-extruded with the frame member. An edge line of the sealing member is presented on the additional layer and is colored with the color of the layer to enhance the outer appearance of the edge line.

Welt system for automotive vehicle

A welt with a fabric covering for a vehicle is disclosed. This welt includes a U-shaped portion for covering an edge of an opening of the vehicle, a rubber seal elastically deformable against shock caused by closing doors, and a fabric sheet wrapping about an area ranging from the U-shaped portion to the rubber seal. Both sides of the fabric are bonded tightly by one adhesive while another area is bonded by a different, pressure sensitive adhesive so as to allow the fabric to be deformed flexibly when the welt is bent.

Covered welt for vehicle

Method for making a window weather stripping having a rough surface including extruding a rubber weather strip material, curing and coating the vulcanized strip with a nylon-based adhesive containing nylon particles.

Method for making weatherstripping having a rough, low-friction surface

Window weather stripping for sealing a gap between a movable glass and a window frame having less frictional sliding resistance and longer life time at relatively lower manufacturing cost. The window weather stripping according to the present invention comprises at least one microscopically rough surface on which the window glass slides, the rough surface being formed by applying a colloidal paint thereon. The colloidal paint is prepared by mixing a synthetic resin paint with a solvent the solubility of which is smaller than that of the synthetic resin or by mixing the colloidal paint obtained as described above with a non-colloidal paint. The synthetic resin is vinyl chloride, urethane-based resin, acryl-based resin, nylon-based resin, polyolefine chlorination-based resin, etc., and the poor solvent is isopropyl alcohol or methanol.

Window weather stripping and the manufacturing method

Window weather stripping for sealing a gap between a movable glass and a window frame having less frictional sliding resistance and longer life time at a lower manufacturing cost. The window weather stripping according present invention comprises at least one microscopically rough surface on which the window glass slides, the rough surface being formed by first painting a bonding agent onto a surface and next spraying particles onto the painted bond or by simply applying a bonding agent mixed with particles. The diameter of the particles is from 5 to 500 micron and the hardness of the particles is from 2 to 7 on the Mohs scale. Talc, nylon, silica, graphite molybdenum, etc. are used as the particles.
