Abstract
The method includes the step of pulling the corrugated board along hot plates by means of an upper flexible member and a lower flexible member driven by two electric motors. By at least one electric parameter of the drive motor of the lower flexible member, the correct operation of the traction device and in particular the correct ratio of the linear feeding speeds of the two flexible members is checked. The method provides an iterative check of the controlled electric parameter and a possible correction of the speed of the flexible members to maintain the desired speed ratio.
