摘要： A method of setting pre-stressing, by which blades (11) of a granulating head carried by a shaft (12) which is driven by a motor (21) and which is displaceable in the axial direction of a granulating device abut against the perforated plate (8), makes use of the torque of the motor (21) for the said setting. To this end, the shaft (12) is adjusted at a constant speed in both axial directions in succession, the pattern of the torque M of the motor (21) being recorded over the displacement path x of the shaft (12) for both directions. The differential dM/dx is formed from this and the position x0 of the shaft is then determined for dM/dx =0. Starting from the said position x0 a position x=x0+xz of the shaft (12) is set, in which xz represents the desired advance of the shaft (12) in the direction towards the perforated plate (8). The device for carrying out this method provides for a sensing device (66) for the time pattern of the torque M of the motor (21). The output signal of the said sensing device (66) influences an actuating drive (75) for the displacement of the shaft (12). In addition, a device (69) for forming the differential dM/dx is provided, as well as a device (70) for determining the position x0 of the shaft (12) for dM/dx =0. The said two devices are connected to the actuating drive (75).
