When a major paper producer was faced with increasingly temperamental performance from the existing hydraulic drive control system on their Valmet KL Winder, they turned to Optima for assistance. The system suffered from uncontrolled starting from cold until the hydraulics had reached normal temperature. However, even at normal operating temperature, there were still issues with tension control being unpredictable.

Optima were asked to suggest possible upgrade solutions for the winder. Their solution was to use a Siemens Sinamics drive system, controlled from their own custom-written winder blocks. 
Optima’s winder blocks are PLC-based and provide all the functionality required of any winding application. 
The new drive system was specifically designed to suit the exact material tensions, roll diameters and operating speeds of the winder to ensure both performance and cost needs were met. The actual products run on winders sometimes differ from the manufacturers own design. 
A complete new control suite was built to house the new PLC and drive hardware. Installation was managed by Optima.
