Abstract
Method of regulating the throughput of a roll press having press rollers, a variable-speed drive motor for said press rollers and a feed device having a controllable throughput. Both the speed of the drive motor and also the throughput of the feed device are regulated automatically in two control modes which succeed one another from time to time. During the first control mode, under nominal loading, the roller speed is increased until the actual loading falls below the nominal loading; at less than the nominal loading the feed throughput is increased until the nominal loading has been attained, and after a condition has been reached in which the nominal loading has not been attained by increasing the throughput, the regulation is changed over to the second control mode. During the second control mode, at less than the nominal loading, the roller speed is reduced until the nominal loading has been attained; at the nominal loading the feed throughput is reduced until the loading falls below the nominal value, and after the loading has fallen below the nominal value, during the second control mode, there is a change-over to the first control mode.
