Unwind/Rewind Guides放卷/收卷糾偏 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). 一個典型的放卷或收卷系統由一個驅動器，一個感應器和一個控制器組成，驅動器可以側向移動輥筒的位置。因為傳統的固定式導軌有時候是無法很好的完成糾偏工作的，在這種情況下，Fife發明了這款移動式的導軌支架。它不僅可以任意由機電驅動器或者液壓驅動器來提供動力，而且經久耐用，其許用載荷高達10,000磅(4,536千克).
