    • The method includes moving a parison guide and a lower molding portion to substantially vertically align an extruding head, the parison guide and an end of the lower molding portion. Then, the lower molding portion is moved substantially horizontally while extruding a parison from the extruding head, while the parison guide is moved laterally in a direction crossing the moving direction of the lower molding portion in accordance with a shape of a groove of the lower molding portion to accommodate a first portion of the parison in the groove. Subsequently, the parison is cut into a predetermined length when the predetermined length thereof is extruded, while a portion of the parison to be cut is held by a parison pinch. Finally, the parison guide is moved laterally in a direction crossing the moving direction of the lower molding portion in accordance with the shape of the groove while moving the lower molding portion substantially horizontally as the parison pinch is lowered gradually to accommodate a second portion of the parison in the groove.
    • 该方法包括移动型坯引导件和下模制部分以使挤压头,型坯引导件和下模制部分的端部基本垂直对齐。 然后,下模制部分基本上水平地移动,同时从挤压头挤出型坯,同时型坯导向件沿与下成型部分的移动方向交叉的方向横向移动,根据下成型件的凹槽的形状 部分以容纳型腔中的第一部分。 随后,当预定长度被挤出时,型坯被切割成预定长度,而被切割的型坯的一部分由型坯夹紧保持。 最后,型坯引导件在与下模塑部分的移动方向相交的方向上沿着槽的形状横向移动,同时当型坯夹紧件逐渐降低时基本上水平移动下模制件,以容纳第二部分 型坯在凹槽中。
