1-12. (canceled)
A pressure device for use in the production of electrochemical energy storage devices, to bring a force to bear on a first foil section of said energy storage devices during said production, the device comprising:
- a thrust bearing element;
- a pressure element configured to be braced on said thrust bearing element, wherein said pressure element has a cross-sectional area and a lengthwise extension arranged orthogonally to said cross-sectional area, and wherein the dimensions of said cross-sectional area are small compared with said lengthwise extension;
- a fastening element configured to fasten the pressure element to the thrust bearing element, wherein the fastening element is configured to exert a clamping force on said pressure element and said thrust bearing element during said fastening;
- and
- an aligning element, wherein at least parts of said pressure element are separated from said thrust bearing element by said aligning element, wherein said aligning element is configured to be connected in form-fit manner to said pressure device.
The pressure device according to 16, wherein
- the aligning element comprises a first and a second cylindrical section, wherein the two said cylindrical sections are not arranged concentrically with one another,
- the first cylindrical section is mounted rotatably in said pressure element or said thrust bearing element, and
- the second cylindrical section is braced indirectly or directly on the respective other of the two devices.
The pressure device according to 16, wherein the aligning element comprises a wedge element, wherein
- the wedge element has a first wedge surface, a second wedge surface and a wedge support surface,
- the wedge support surface cooperates indirectly or directly with the pressure element or the thrust bearing element, and
- the first wedge surface is mounted so as to be movable relative to the respective other of the two elements.
The pressure device according to 16, wherein
- the aligning element comprises a lever device connect to the pressure element or the thrust bearing element by a swivel joint, and
- the aligning element has a lever bracing surface, wherein the level bracing surface is braced indirectly or directly on the respective other of the two devices.
