摘要： Reclamation of vulcanized rubber is effected by a method which comprises heating powdered vulcanized rubber to a temperature for desulfurization of the rubber and, on completion of the desulfurization, quickly cooling the desulfurized rubber to a temperature at which substantially no oxidation of desulfurized rubber proceeds. This method obviates otherwise indispensable incorporation of process oil or other similar additive to the powdered vulcanized rubber for the purpose of retarding the oxidation of rubber molecules. When the reclaimed rubber obtained by this method is blended with newly supplied rubber, the resultant vulcanized rubber shows sparing degradation of physical properties.

摘要翻译： 硫化橡胶的回收是通过将硫化橡胶加热至橡胶脱硫的温度来进行的，在脱硫完成时迅速将脱硫橡胶冷却至基本上不脱硫硫化橡胶的温度。 为了阻止橡胶分子的氧化，该方法避免了与粉末状硫化橡胶不同的工艺油或其它类似添加剂的不可或缺的组合。 当通过该方法获得的再生橡胶与新供应的橡胶混合时，得到的硫化橡胶显示出物理性能的降低。

摘要： A U-shaped insert for a weather strip includes a plurality of segments, which are spaced apart by a predetermined interval. Adjacent pairs of the segments are attached together by a pair of coupling members. The coupling members of each pair of the segments are substantially parallel to one another. Acutely angled corners are formed by each coupling member and the segments to which it is attached. The acutely angled corners include notches, which are cylindrical and extend into the associated segment. This permits deformation of the insert, while the insert resists tensile deformation.

摘要： The present invention is directed to a door weather strip in which the corner portions thereof are integrally formed with straight portions thereof. In order to obtain a predetermined sealing interference, the cross sectional shape of the corner portions of hollow sealing portion and the lip seal of the weather strip is arranged to be longer than that in the straight portion. Alternatively, the sealing portion is raised as to have a predetermined shape when the corners are formed. Said formed shapes are solidified by vulcanization after the weather strip has been plastic deformed before the vulcanization.

摘要： The present invention relates to a trim or a seal member such as an opening trim weather strip. The trim or a trim body in the seal member has a holding lip portion and modified holding lip portions. And the holding lip portion and modified holding lip portions have head portions. The head portions are made to bulge out toward a bottom wall portion at the tip ends of modified holding lip portions of the trim or the trim body of trim portion. The modified holding lip portions are formed so that projecting lengths of the head portions from the end surfaces of tip end portions of the modified holding lip portions, and the thicknesses of the head portions increase in inverse proportion to lip projecting lengths of the modified holding lip portions from an inner surface of an interior side wall portion. Alternatively, a slope inclined with respect to an extension plane of an opening-portion-side surface of a base end portion is formed at tip ends of the modified holding lip portions. The slope is formed so that the inclination angle with respect to the extension plane increases in accordance with the projecting lengths of the modified holding lip portions.

摘要： A die is formed with an opening having substantially the same shape as a fundamental cross-sectional shape of an extrusion member. A first core is formed with a projecting portion projecting forward beyond a front surface of the die. A movable die for changing the external shape of a sealing portion is disposed on the front surface of the die. The movable die is allowed to move between a position where a curved surface formed at the forward end thereof is kept away from the projecting portion of the first core and another position where the curved surface comes close to the projecting portion. Further, first and second movable cores are inserted in the opening of the die, these movable cores being moved forward and backward along the direction in which EPDM is extruded.

摘要： An apparatus for extruding a weather strip having first and second function portions and a connecting portion interconnecting these function portions is disclosed. The connecting portion varies in width according to a longitudinal position along the weather strip. Included in the apparatus is a head, a main die plate which is mated with a front side of the head and which has a first opening for extruding rubber therethrough to form a first function portion, such as a mounting portion, and part of the connecting portion, a fixed die plate connected to the main die plate, and a movable die disposed in the fixed die plate. The movable die has a second opening for extruding rubber therethrough to form a second function portion, such as a sealing portion, and part of the connecting portion and is slidably received in a reception portion in the fixed die plate. A discharge rate of the rubber for forming the connecting portion is adjustable in accordance with the sliding movement of the movable die. Burrs on the resulting weather strip are therefore avoided. Also, sacrificial portions of the rubber are not generated. The second opening in the movable die is formed into a required special configuration, and by moving the movable die, the width of the connecting portion can be easily varied while maintaining the shape of the seal portion.
