    • The invention relates to a screw press of the kind which incorporates a screw, in the machine or press frame, operated by a fly wheel continuously rotating in one direction, the fly wheel and screw having a releasable coupling connecting them the coupling being released on the attainment of a predetermined pressing effect. The invention is particularly concerned with the release of the coupling and provides a press wherein the release of the coupling is effected to remove as much energy as possible from the fly wheel before the uncoupling is effected the construction being such that the release takes place on the falling below of a predetermined angular velocity and/or the exceeding of predetermined angular retardation of the screw.

    • A screw press has a rotary screw (5), a flywheel (8) that turns without interruption in one direction of rotation, a hydraulically controlled friction clutch whose coupling disk (12) establishes a frictional connection between the screw (5) and the flywheel (8) to produce a working stroke, and a restoring rotary drive (15; 23) for moving backwards a tool carriage (3) that moves back and forth in the swept volume inside the machine body. To compensate for the weight of the tool carriage (3), the tool carriage (3) is connected to pneumatic cylinders (13) that have an accumulation-compression chamber (27), a cylinder chamber (26a) at the top side of the piston and a cylinder chamber (26b) at the bottom side of the piston.

    • A spindle press of the type in which an inertial mass controls the clutch connecting a continuously rotatable flywheel with the spindle and is effective when the ram is retarded to decouple the spindle from the flywheel. The control unit is provided directly on the ram and the mass is arranged so as to be movable at least with its principal component of movement in the working direction of displacement of the ram, thereby excluding from significance any distortion of the spindle and the spindle nut drive between the ram and the flywheel.

    • A slide is vertically movable in a press frame and supports the upper die. A threaded main spindle is operative between the press frame and the slide. A clutch disc connected rationally rigidly to the spindle is connectable by friction contact to a driven disc flywheel for the operating stroke of the slide. Piston-cylinder units act between the press frame and the slide for returning the slide to the starting position. The spindle is axially clamped between two spring columns, one of which acts between one end of the spindle and the slide and the other of which acts between the other end of the spindle and a counter thrust bearing axially fixed in the press frame. An auxiliary spindle, of approximately the same lead but with a smaller diameter, engages in an internally threaded bore in the main spindle and is disposed between the corresponding end of the main spindle and the corresponding spring column in order to compensate the relative axial movement between the axially fixed main spindle and the axially movable slide or between the main spindle axially movable with the slide and the counter thrust bearing held axially movably but rotationally rigidly in the slide or on the counter thrust bearing against the force exerted upon it by the spring column.
