    • A high-speed printer in which the carriage carrying a print wheel is coupled to a servo controlled driving motor having intermittent motion. The motor drives a helically grooved pulley, which has attached to it left and right cable segments. The other ends of the cable segments are attached to the movable carriage. A cable preload spring and friction pulley snubber combination maintains cable tension relatively constant. The snubber provides a tight cable system during normal carriage acceleration and deceleration. The preload spring allows for tension correction when the cable suffers from long-term stretching due to constructional stretching, that is, the normal tendency of wound cables to stretch due to seating of individual wires in the strand.
    • 一种高速打印机,其中携带打印轮的滑架与具有间歇运动的伺服控制的驱动电机相连。 电动机驱动一个螺旋槽式滑轮,其连接到其左侧和右侧的电缆段。 电缆段的另一端连接到可移动的托架上。 电缆预紧弹簧和摩擦滑轮缓冲组合保持电缆张力相对恒定。 缓冲器在正常滑架加速和减速期间提供紧密的电缆系统。 当电缆由于结构拉伸而遭受长期拉伸时,预压弹簧允许张力校正,即由于单根线在线中的放置而使缠绕电缆拉伸的正常倾向。
