The forces of the plough - from the drive unit to the picks - have been discussed. Exampies have been shown to reduce the forces of cutting and the forces unusable (forces of friction), to aminimum. Furthermore it was ensured, that the plough remains in the horizon of the sceam. An exampie shows, that the production increases by enlarging the depth of the cut of 150 Ofo. By this the force of the ca in could be reduced by 40 Ofo at the same time. Resume Les forces provenant du rabot, allant depuis la t te motrice jusqu'aux pies, ont ete discutees. I1 s'est trouve des possibilites, de reduire au minimum Ies forces de coupe et les forces inutiles (forces de friction) et par la m me occasion, de veiller a ce que Ia tenue du rabot dans I'horizont de couche, soit assuree. I1 est possible de prouver l'augmentation de la quantite productive grice a un agrandissement de 150 % de Ia profondeur de coupe, ce qui entraine egalement une reduction d'environ 40 % de la force de traction au tourteau d'entrainement. Möglichkeiten der Verwirklichung von Forschungs- und Versuchsergebnissen in der Konstruktion von Maschinen für die schälende Kohlengewinnung Von Lothar Freytag, Westfalia Lünen Es ist mir eine besondere Freude, in Ihrem Kreis ein Korreferat zu dem von Herrn Professor Sann behandelten Themenkreis halten zu dürfen.
