Doubling Lines

The CCD CAM 100 high-resolution cameras provide the ideal basis for perfect doubling. In conjunction with BST Group web tension measuring systems and intelligent actuators, high-precision results can be achieved in the doubling of primary materials. On the winder, web guide controllers and web tension control systems ensure winding with straight edges and gentle liner handling.


Depending of the tire design, BST Group provides individual doubling solutions based on tried and tested components and guiding technologies and the high-performance camera CCD CAM 100.

Winder Guiding System

The SmartGuide.WF ensures the controlled unwinding and rewinding of material and liner. A large range of proven components, such as controllers and actuators, facilitate adjustments for specific tasks.

Web Tension Measuring Systems

The BTL Load 100-500 cells control the tensions of the rubber material and the textile cord during their run through the calender line, and the web and the liner at the winder.

Laser Marker

Guided by defined recipe data, the NCA Laser 100 indicates the correct edge position of the web.

Conveyor Guiding

In combination with various sensors, selected according to the material to be controlled, the actuators control the conveyor belts to bring the material to its correct position.
