Torque control for drying rolls of sizing dryer - torque exerted on warp ends is maintained with accuracy in all phases

摘要

A torque control unit is for the drying rolls of a sizing dryer in which a number of sized warp ends are guided via drying rolls. The rolls are connected to a drive via a torque converter coupling and, at the same time, the torque transmitted by the coupling is controlled through a torque control so that the torque required for the acceleration and deceleration phases and for the constant speed phase is maintained with accuracy. ADVANTAGE - The control system achieves a constantly ideal torque distribution.
