When the mold is opened, the side core 62 is slid. By this, the center core main body 63 is separated from the side core main bodies 66L and 66R to pull out the center core main body 63 from the weather strip, and then the side core main bodies 66L and 66R are pulled out. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
