On a sectional paper machine the wet section runs master/slave load sharing: the driven sections follow the master not just by speed but by torque, so the load divides correctly across the machine. What makes it useful in practice is that the sharing ratio is not a fixed number.
As the grade, basis weight, machine speed, wire tension and vacuum change, the load-sharing ratio adjusts automatically. A heavier grade or higher speed shifts more torque to where the machine needs it; a lighter run eases off. The operator sets the production target, and the drive system rebalances the sections without a manual retune.
This is the behaviour our MCS package delivers on a 4800 mm machine: stable production across a wide operating envelope, instead of a line that needs constant operator correction every time the recipe changes.
