Abstract

A method for controlling the run-up of a conveyor belt BY increasing a setpoint value of the belt's speed with an increasing acceleration in a first time interval, and with a decreasing acceleration in a second time interval, thereafter plotting a curve of the increasing acceleration against time which has a positive curvature in the second interval, a second time derivative of the acceleration in the first and the second time interval is at least approximately constant and at least approximately equal and opposite.
