旋转纠偏辊架（DF）
旋转纠偏辊架由一个固定的下支架和一个可旋转的上支架组成，上支架的支点位于物料的进料端。当进料路径发生错误时，上支架将绕支点旋转，使得物料在下一个纠偏辊筒处进入正确的设定位置。
旋转纠偏辊架适用于物料须在较短距离内和zui小表面张力的情况下实现纠偏。其他优势还包括安装位置灵活，所需的推力较小。因此，旋转纠偏辊架特别适合于对表面张力敏感的物料。
Rotating frame guide (DF)
The KADO rotating frame guide is comprised of a fixed lower frame and a rotating upper frame, whose pivot is located on the in feed of the web.
An incoming web path error causes the upper frame to rotate around its pivot point to move the web of material into a defined position on the next guiding roller.
This guiding device is used if the web path must be corrected within a short distance and a minimum of material stress. Further advantages are the variable installation positions and the low actuating forces required. The KADO rotating frame guide is thus particularly suitable for web tension sensitive materials.
