- Web-guiding systems are used in the converting industry to position flat materials, known as webs, before processing. They are typically positioned just before a critical stage on a . Each type of web guiding system uses a sensor to monitor the for , and each has an actuator to shift the running web mechanically back on course whenever the sensor detects movement away from the set path. Actuators may be pneumatic or hydraulic cylinders, or some kind of . Because the web may be fragile — particularly at its edge — non-contact sensors are used. These sensors may be pneumatic, photoelectric, ultrasonic, or infrared. The system’s controls must put the output signals from the sensors in to a form that can drive the actuator. Web guiding systems work at high speed, constantly making small adjustments to maintain the position of the material. The latest systems use digital technology and touch screen operator interfaces to simplify set up. Web guiding systems are used on slitting machines, slitter rewinders, printing presses, coating and laminating machines. (en)
- 卷料導引系統（Web-guiding systems）是在工廠中針對卷料片材進行處理前，針對片材定位的設備。卷料在加工處理時，會先經由設備，將卷料展開成為長條薄片狀，在處理後，再重新卷成卷料。卷料導引系統可能是放在卷料展開後的關鍵位置，也有可能是在重新卷成卷料前的關鍵位置。 卷料導引系統都會用感測器來監控卷料位置，進行橫向跟踪，也會有致動器，在卷料偏離理想位置時調整其橫向位置。致動器可能是氣動設備、液壓缸、也有可能是機電設備。因為卷料多半是易破的材質（尤其是其邊緣），一般會使用非接觸式感測器，可能是液壓、光电、超音波或是红外线的感測器。控制系統需根據感測器的訊號輸出訊號到致動器。 卷料導引系統以高速運作，持續的對卷料位置作小幅的調整。最新型的系統會利用數位科技以及觸碰式螢幕來簡化設置。卷料導引系統會用在、分切複捲機、印刷机、塗佈和層壓機。 (zh)
