    • A high speed media management device has tractor means for moving a web through the device past a plurality of work stations at each of which the web may be treated. Relatively high web tension is maintained throughout its travel path. Counting means near the beginning of the web path generate a count signal with the passage of each increment of web. The accumulated count signals are compared to numbers stored in a plurality of registers, each register associated with a work station and each containing a count representative of web travel distance relative to the work station. The first register count corresponds to the distance required to accelerate the web from a stop. The remaining registers store that count and a separate count representing the distance between the first station and the corresponding station. When the counter contents equals the count in a register, an actuating signal initiates a treatment activity at the associated work station. At predetermined intervals thereafter, additional actuating signals generated and applied.
    • 高速媒体管理装置具有牵引装置,用于通过装置移动网通过多个工作站,每个工作站可以对其进行处理。 在其行进路径上保持相对较高的卷材张力。 网路路径开始附近的计数意味着每个网页增量都会产生一个计数信号。 将累积的计数信号与存储在多个寄存器中的数字进行比较,每个寄存器与工作站相关联,并且每个寄存器包含相对于工作站的代表web行进距离的计数。 第一个寄存器计数对应于从停止加速网络所需的距离。 剩余的寄存器存储该计数和表示第一站和相应站之间的距离的单独计数。 当计数器内容等于寄存器中的计数时,致动信号在相关联的工作站发起处理活动。 此后,以预定的间隔产生并施加附加的致动信号。
