 We are in the position to announce the completion of the 1st step of upgrading Jagenberg Varidur winder in Macedonian Paper Mills S.A( MEL) in Greece.

MEL awarded us with the project and the teams of SAEL & TECNOPAPER realised the project between 4-8 Aughust 2015 with success. After the second inspection we performed in September, we can say that the project was completely satisfactory according to our goals.

The challenge was to eliminate problems appearing during the cutting in the tension control, torque control between the two drums, which created friction in the coating  and also the phenomenon of overlapping. The other issue was to change the complete drive and control of the machine because was outdated and without any spare parts.

Tecnopaper performed a combination of works, repostioning paper roll, installing 2 new bowed rolls and also load cells. These actions resulted to overcome the problems of tension( load cells give automatic tension through SAEL supervisor) and also we decreased the overlapping effect with the possibility to pass the paper in the correct curve.

Above to that, SAEL installation of new cabinets with new PLATFORM ONE DRIVES in combination with new encoders in the two old DC motors, gave us the power to have a completely digital system in the Scalink supervisor, giving the opportunity to MEL operators to effectively control the tension through the load cells and new pnevmatic unit in the brake and also to perfectly adjust the torque between the two drums, avoiding slipping of paper and friction in the coating side. The end reels are now of obvious better quality.

Also with modernising the complete drive system, we have managed to increase the speed of the machine by 10%.

Finally with the new SAEL Scalink Supervisor we gave the power to MEL people to have in their hands a new system in order to control, adjust and parametring their machine according to their production needs.


I would like to thank Macedonian Paper Mills technical team for their important and organised work and their good coordination with SAEL and Tecnopaper teams during this project, that allowed us to restart the machine in less than 72 Hours!!!
