Proposed is a transfer system for presses, having at least two fastening units arranged opposite one another, wherein each of the fastening units in each case has a first fastening region. The transfer system further has a press transfer unit, consisting of two movement arms arranged opposite one another, as well as a crossbar connected thereto for receiving and for transporting, i.e. including setting down, a workpiece. Each of the movement arms has a first drive unit connected to the first fastening region, a first lever arm, a second drive unit, and a second lever arm. The first lever arm is connected at a first end thereof or between the first and a second end to the first drive unit, and at the second end thereof to the second drive unit. The second lever arm is rotatably connected at a first end thereof to the second drive unit, and is movably connected with a second end thereof to the crossbar. In addition, at least one energy-storing element is provided for each movement arm, which energy-storing element is formed and arranged in such a way that its force or a force component thereof points in the acceleration direction of the crossbar with or without workpiece. In an embodiment c1, a second fastening region is provided on the fastening unit, and the energy-storing element is connected directly or indirectly with a first end thereof to the second fastening region, and is fastened on a second end thereof at a specified region of the movement arm. In an additional or alternative embodiment c2, the energy-storing element is fastened with a first end to the first lever arm and with a second end thereof to the second lever arm.

An arrangement for pressing materials containing liquid has mobile press container with an container interior that is divided by a press membrane into a pressure medium chamber and a pressing medium chamber. A filling and emptying opening, which can be closed in a pressure-tight manner, allows material to be pressed to be added to the pressing medium chamber. At least one drainage element is arranged in the pressing medium chamber. An interior of the drainage element communicates with a juice discharge of the press container. A turning device, in which the mobile press container is temporarily received can be rotated during a pressing operation from a filling position, about an angle of less than 360°, more particularly of less than 270°, in mutually opposing directions of rotation about an axis of rotation. There is also described a method for pressing liquid-containing materials.

Auto-aligning vacuum presses, that include a mobile assembly with a first platen, a vacuum docking station with a second platen, a first locating device to guide the mobile assembly to a desired location along the Y-axis as the mobile assembly moves along the X-axis into the vacuum station, and a second locating device to guide one of the first and second platens along the Z-axis into sealing engagement with the other platen.

A device is described for continuously pressing liquid out of a suspension, in particular a screw press, which may have a rotationally-driven rotor, which may rotate in a tubular screw housing and support a conveyor screw. The screw housing may be at least partially formed as a first filter jacket, which may at least partially interact with the conveyor screw and which may have radial passages for discharging the filtered liquid and which may supply a filter cake, made of retained solids, in the conveyance direction of the conveyor screw to a discharge. To provide advantageous filter conditions, a ring-shaped first sleeve, which coaxially encloses the rotor, for peeling off an outer filter cake layer from the filter cake may be associated with the rotor, downstream from the conveyor screw. A conveyance channel for the remaining inner filter cake layer may be provided between sleeve and rotor.
