Beschreibung
Zusammenfassung:	A control system for a continuously operating press, for the manufacture of chipboard, molded laminated plastic and the like, having two endless revolving forming belts which advance opposite each other in a pressing section, between which a starting material is compressed in the pressing section and each of which belts is provided with a separate drive, one of the drives being a lead drive equipped with a speed control for holding the belt velocity constant, in which there is provided a torque controller for comparing the torque of the lead drive with the torque of the other drive and providing an output which regulates the torque of the other drive such that the torques of the two drives always retain an adjustable ratio between each other over the entire torque range; and a further speed control for the belt drive which is not operating as the lead drive which is set higher than the speed control of the lead drive and which is adapted to be adjusted along with the speed control of the lead drive, with the speed ratio remaining the same.
