    摘要： A heated, segmented pressware die set for making pressware containers from a paperboard blank includes a plurality of guide keys mounted between at least one of an inner member of a punch or die and an outer ring which reciprocates independently. Each guide key extends in an outward direction from the central axis of the die set. The guide keys are positioned, configured and dimensioned to engage the outer ring in order to limit rotation of the outer ring with respect to the inner member of the punch or die. In a preferred construction, the guide keys have radially extending planar surfaces which cooperate with guide channels having like surfaces such that clearances necessary to accommodate thermal expansion are reduced, greatly increasing durability of the tool.

    摘要翻译： 用于从纸板坯料制造压制容器的加热的分段压模模具包括安装在冲头或模具的内部构件中的至少一个与独立往复运动的外圈之间的多个导向键。 每个导向键从模具的中心轴向外延伸。 导向键被定位，构造和尺寸设计成与外圈接合，以便限制外圈相对于冲头或模具的内部构件的旋转。 在优选结构中，导向键具有径向延伸的平坦表面，其与具有相似表面的引导通道配合，使得适应热膨胀所需的间隙减小，大大提高了工具的耐久性。

    摘要： In an apparatus for manufacturing pressware containers from container blanks there is provided a plurality of inertial blank stop pins disposed so as to position a container blank prior to press forming. The stop pins are rotatable in order to absorb the kinetic energy of the container blanks as they are fed to the apparatus and eliminate blank bounce. In a further aspect of the invention there is provided a method of forming plates utilizing the improved apparatus including the inertial blank stop pins.
