This paper describes the reconstruction of the drives of a paper machine for the press and drying part of the machine during June, 2001, as well as the expansion of the paper machine with a "third coating" during July, 2002 at the board factory "Umka". The existing old drive of the press and the drying groups was realized as a 76 meter long line shaft drive. The coating section of the machine was realized with sectional drives with DC motors fed from thyristor converters. The concept of the new drive is based on standard squirrel cage induction motors, fed from frequency converters. The system is controlled by a programmable logic controller. The communication between the controller, frequency converters and control panels is realized with a profibus protocol. The Laboratory for Electric Drives, of the Faculty of Electrical Engineering, Belgrade, was contracted for the drive part of the reconstruction of the paper-board machine. The complete project, supervision of the work of the investor's own technical services and final commissioning of the drives were organized in such a way that the drives were changed during the planned periods for the repair of the machine
