METHOD AND APPARATUS FOR SETTING A CLAMPING LOAD ABSTRACT OF THE DISCLOSURE The clamping preload in a molding machine or the like is set by adjusting the length of tie bars which support two die plates for opening and closing movement and a thrust plate. A clamping mechanism of given stroke is positioned between the thrust plate and one of the die plates, and operates to close the die plates at one limit of the clamping stroke. With the clamping mechanism set at its limit and the tie bars set to establish a slight spacing between the die plates, the length of the tie bars is adjusted by means of a drive motor until the die plates are in contact without substantial preload. The clamping mechanism then opens the die plates and the drive motor is further energized to adjust the length of the tie bars and bring the die plates closer to one another by an amount corresponding to a preselected preload. The adjustment is measured from a high ratio mechanical drive connecting the drive motor to the adjustable tie bars, and the measured adjustment is compared with a desired adjustment corresponding to the preselected preload to deenergize the drive motor when the desired adjustment is reached. -1-
