    • A method of working paperboard blanks is disclosed. The method includes providing first and second pairs of parallel rotary shafts supporting first and second pairs of tool heads respectively. The first pair of tool heads is moved to a predetermined longitudinal position along the first pair of shafts to define a first line of working. Likewise, the second pair of tool heads is moved to a predetermined longitudinal position along the second pair of shafts to define a second line of working wherein a center of the first line of working is displaced relative to a center of the second line of working. The paperboard blank is conveyed between the first and second pairs of tool heads to form a panel line on the paperboard blank. The tool heads may be automatically positioned along their respective shafts by coupling members which move linearly parallel to the shafts.
    • 公开了一种纸板坯的加工方法。 该方法包括分别提供支撑第一和第二对工具头的第一对和第二对平行旋转轴。 第一对工具头沿着第一对轴移动到预定的纵向位置以限定第一工作线。 类似地,第二对工具头沿着第二对轴移动到预定的纵向位置以限定第二工作线,其中第一工作线的中心相对于第二工作线的中心移位。 纸板坯料在第一和第二对工具头之间传送以在纸板坯上形成面板线。 工具头可以通过与轴直线平行移动的联接构件沿其相应的轴自动定位。
