    In this paper the working stroke of a screw press is onalyzed, leading to for- mulas for the determination of the maximum stress in its frame. The working stroke is considered to consist of two successive stages: (1)the stage of plastic deformation of the workpiece and (2) the stage of braking the flywheel of the press to a stop. Since the maximum force Pm acting upon the frame may accidentally occur at the end of the second stage of the working stroke when there is no stock in the die. the value Pm is required in the calculation of the frame strength. The strength calculation for the integral closed-type frame of a screw press then proceeds as follows: (1) Drawing the bending moment diagram with the unknown Pm (being in nature a statically indeterminate problem with respect, to the internal bending moment, this may be solved by means of the canonical equations of the force method); (2) Calculating the strain energy stored up in the frame and in the threaded spindle at well as the expended friction work during the whole working stroke, then determining the maximum load Pm; (3) Supplying the bending moment diagram with numerical data in order to find where the maximum stress in the frame exists and check up whether it is within the magnitude of the safe stress of the frame material.
