rewind是什么意思

Unwind/Rewind Guides放卷/收卷纠偏 A typical unwind or rewind system consists of an actuator to move the roll laterally, a sensor, and a controller. In some cases, however, traditional guiding systems will not work. If a suitable roll stand is not available, Fife will provide the Shifta-Roll Positioning Stand. Powered by either electromechanical or hydraulic cylinders, these durable stands are capable of handling loads up to 10,000 lbs (4,536 kg). 一个典型的放卷或收卷系统由一个驱动器，一个感应器和一个控制器组成，驱动器可以侧向移动辊筒的位置。因为传统的固定式导轨有时候是无法很好的完成纠偏工作的，在这种情况下，Fife发明了这款移动式的导轨支架。它不仅可以任意由机电驱动器或者液压驱动器来提供动力，而且经久耐用，其许用载荷高达10,000磅(4,536千克).
