Winder Control

When unwinding a web, the material should run into the machine in a defined position. At the end of the machine the material should be rewound in optimum quality to facilitate the material positioning for the subsequent process machines.

The BST eltromat unwinder and rewinder web guiding systems allow for precise material guiding with application-dependent sensors, controllers, and actuato


Static and minor dynamic defects in the position of the incoming material

Application Areas

All unwinder and rewinder applications


  • Rewinder control with CCD cameras
  • Manually-operated sensor adjustment device HFVG
  • Motorized sensor adjustment device FVG with automatic edge detection

System Accuracy

Depending on the sensor used, the achievable system precision can be less than 1 mm.
