摘要： Torque equalizing mechanism for uniformly actuating the die cores of a double parison extrusion head on a vertical ''''wheeltype'''' blow-molding machine and uniformly varying the wall thickness of a pair of parisons simultaneously extruded from the head. A single programming means governs operation of the actuating mechanism. Die cores, extending upwardly from the double extrusion head, are engaged by rocker arms fixed on a rotatably mounted tubular shaft section of a composite shaft having a driver rod fixed internally thereof at a localized central attachment area equidistant from the die core centers. The rod extends from one end of the tube and a crank arm on the outer end of the rod is linked to a control shaft movable in response to the single programming means. The composite tubular shaft arrangement applies motion to the die cores equally and requires a minimum of head space for a double parison die head, thus facilitating the conversion of existing single parison machine designs to double the output thereof.

摘要翻译：用于在垂直“轮式”吹塑机上均匀地驱动双型坯挤压头的模芯的扭矩均衡机构，并均匀地改变从头部同时挤出的一对型坯的壁厚。单个编程装置控制致动机构的操作。从双挤出头向上延伸的模芯通过固定在可旋转地安装的复合轴的管状轴部分上的摇臂接合，该复合轴具有在其内部固定有与模芯中心等距的局部中心附着区域的驱动杆。杆从管的一端延伸，并且杆的外端上的曲柄臂可枢转地连接到可响应于单个编程装置移动的控制轴。复合管状轴装置同样地对模芯施加运动，并且需要来自双型坯模头的最小的顶部空间，从而便于将现有的单型坯机设计转换成其双倍的输出。
