The WBG-03 Web Guider

The WBG-03 Web Guider is designed for guiding paper and plastic film webs.

It consists of:

  • A base
  • A pivoting frame with two idle rolls: the entry idle roll and the exit idle roll
  • An edge sensor, installed on its adjusting frame
  • An electric servo actuator
  • A control cabinet.

Its guiding action is achieved by moving the idle rolls installed on the pivoting frame radially and laterally, simultaneously.

The pivoting frame is driven by the electric servo actuator according to a signal from the edge sensor. The ES-2  is a high resolution edge sensor able to guide the web up to +/-0.5mm. The edge sensor’s signal value is close to 0V when  the web is in desired position, otherwise the signal causes the electric servo actuator to extend or retract with a speed proportional to the signal’s value, thus guiding the web very accurately.
