Belt tensioning and tracking systems Continuous tension and precision across the board

Optimum tensioning force and tracking precision Temperature fluctuations, mechanical stress, contamination, and high pressure cause strain on steel belts during daily use. This can lead to premature wear of the belt and imperfect belt tracking, eventually leading to operational downtime. To ensure smooth product processes, Berndorf Band Group has developed two systems for the tensioning and tracking of belts – the bernmatic® tensioning and tracking system and the berntrack® pure belt tracking system for installations that already have a tensioning system in place.

n Increased system availability and higher system productivity n Time-saving due to eliminating belt tracking problems n Automatic adaptation of the system after the first few production runs n Ensure optimum belt tracking by continuous proportional control of the belt Customers often approach us, who have problems with belt damage and the resulting production downtime. During inspection by our experts, insufficient belt control and tension can quickly be identified as the cause of the fault. If all influence factors for optimum belt position and tension are not taken into consideration,...

Precision belt tracking with bernmatic® belt tensioning and tracking system This technologically advanced solution for belt tracking relies on horizontal adjustment of the deflection drum position. The deflection drum is automatically brought to the perfect position to keep belt tension constant and ensure straight belt tracking. Should an incorrect belt tracking line arise, the system immediately corrects its position, ensuring a longer belt lifetime. Speed-independent control is particularly precise and reliable even at high speeds. The system also scores with its simple operation by...
