摘要： A mechanism for clamping a flexible metal printing plate to the circumferential surface of a rotatable plotter drum is provided. The clamping mechanism includes a mounting member affixed to the drum's surface. The mounting member has a passage aligned radially with respect to the drum. A slidable member extends through the passage and past the drum's axis of rotation. The slidable member has, at one end, a head and, at the other end, a weight. The clamp head is disposed further from the axis of rotation than the mounting member and adjacent the drum surface so as to permit clamping between the head and the drum surface. The slidable member is disposed so that its center of mass is opposite the drum's axis of rotation from the head. A mechanism, such as a compressed spring mounted between the weight and the mounting member, is provided for urging the slidable member so as to force the head towards the drum surface. An actuator having two modes is also provided. In the first mode, it forces the slidable member so as to move the head away from the drum surface and, in its second mode, it permits the head to be urged towards the drum surface by the urging means. The clamping mechanism is also provided with a mechanism for turning the slidable member, so that every time the actuator goes into the second mode the clamp head is turned 90 DEG from the previous time the actuator went into the second mode.
摘要翻译：提供了一种用于将柔性金属印刷板夹紧到可旋转绘图机滚筒的圆周表面上的机构。夹紧机构包括固定在滚筒表面上的安装件。安装构件具有相对于滚筒径向对准的通道。滑动构件延伸穿过通道并经过滚筒的旋转轴线。滑动构件的一端具有头部，另一端具有重量。夹头设置为比安装构件更远离旋转轴线并且邻近鼓表面，以允许夹头与鼓表面之间的夹紧。可滑动构件设置成使得其质心与鼓的头部旋转轴线相反。提供了一种诸如安装在重物和安装构件之间的压缩弹簧的机构，用于推动可滑动构件以将头朝向鼓表面。还提供了具有两种模式的致动器。在第一模式中，其迫使可滑动构件将头部从鼓表面移开，并且在其第二模式中，允许头部被推动装置推向鼓表面。夹紧机构还设置有用于转动可滑动构件的机构，使得每次致动器进入第二模式时，夹具头从前一次执行器进入第二模式转动90度。

摘要： A rotatable drum for use in a plotter, or similar device, that provides vacuum for holding the film or other media to the drum's surface, so as to easily accommodate films of various sizes. The drum includes first and second journals (10) and a plate (7) mounted on the circumference of the first and second journals. At least one of the journals has defined on its circumference circumferential channels. The plate (7) has interior and exterior sides, and the first and second journals and a portion of the plate's interior side define a chamber (3). The plate's exterior side has defined thereon a plurality of grooves (72). In one embodiment, at least one of the grooves, associated with a first film size, is in fluid communication with the chamber (3), and some of the remaining grooves, associated with the larger film sizes, are in fluid communication with the channels. A vacuum is supplied to the chamber, and a valve (50) is provided for controlling fluid communication between the channels and the chamber.
