摘要： An automobile weather strip having a main body made of a sulfur-vulcanizable ethylene propylene rubber (EPDM) type compound and having a portion designed to be in contact with a sealer when the weather strip is mounted to an automobile. A sealer underlying layer is included that will be in contact with the sealer with that layer comprised of a bondability improving EPDM type compound and coextruded together with the main body. The bondability improving EPDM type compound is based on a blended polymer having a blending ratio: ______________________________________ EPDM type polymer 60-96 wt % NBR type polymer 2-30 wt % hydrogenated SBR type polymer 2-30 wt %. ______________________________________ A practical bondability can be ensured between the weather strip and the sealer with no pretreatment, such as by buff fabrication, to a portion of the weather strip to be abutted to or in contact with the sealer.

摘要： A door glass run includes a door glass run body having a U-shaped cross section, and a pair of lip portions each one of the lip portions extending from opposite sides of an opening edge of the door glass run body toward a bottom face portion of the door glass run body and effective to slidably contact with the door glass. The lip portions have lengths individually set so that, even if the door glass vibrates in the door glass run, the lip portions will not be spaced away from the door glass. Alternatively, a protrusion is provided on an inner wall face of the door glass run body. A height of the protrusion is set so that, even if the door glass vibrates, an end portion of one lip portion closest to the protrusion does not contact with an inner wall face of the door glass run body.

摘要： A method and a device for forming a molded portion at an end of an extruded weather strip. The method includes the steps of placing the end of the extruded weather strip made of foamed elastic material in a cavity defined by a movable upper mold member and a fixed lower mold member which composes a mold, closing the mold with the end of the extruded weather strip clamped by a predetermined clamping force, injecting a foamable molding material into the cavity, moving the upper mold member up by an force not more than the clamping amount in the process of foaming of the foamable molding material to reduce clamping of the upper mold member and to enlarge the cavity, continuing molding with the upper mold member moved up until the foamable molding material fills the enlarged cavity, and opening the mold when molding of the molded portion is completed. The device has a fixed lower mold member, a movable upper mold member, a servomotor, and power transmission means for connecting the servomotor to the upper mold member and converting a rotary movement of the servomotor to a vertical movement of the upper mold member, whereby the upper mold member is moved up and down by a predetermined amount and in a predetermined timing.

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.

摘要： A method for forming an extruded weather strip having a trim portion and a lip having a thickened end portion. The method includes the steps of: extruding unvulcanized rubber through a head mounted on a downstream end of an extruder; roughly shaping the extruded unvulcanized rubber by causing the extruded unvulcanized rubber to move through an opening formed in a main die plate disposed downstream of the head so as to shape a portion of the extruded unvulcanized rubber corresponding to the trim portion and a portion of the extruded unvulcanized rubber corresponding to the lip into a shape having a width not smaller than the maximum width of the lip to be finally formed; forming the thickened end portion by causing the shaped unvulcanized rubber to pass through a space defined by a movable orifice plate which is disposed downstream of the main die plate and, while moving the movable orifice plate in the direction of width of the weather strip; and shaping the end of the lip by further advancing the shaped unvulcanized rubber through an end shaping structure, while moving the end shaping structure substantially together with the movable orifice plate.
