  • Publication number: 20260225359
    Abstract: The invention relates to a laminating apparatus for a multilayer endless web (3) composed of at least one separator web (4, 6) and at least one electrode for producing energy cells using a pressing device which laminates the multilayer endless web (3) over a pressing surface by exerting a compressive force. The pressing surface has various portions having a different spring stiffness.

  • Publication number: 20260135132
    Abstract: The invention relates to a laminating apparatus for a multilayer continuous web made up of at least one separator web and at least one electrode for producing energy cells and that has a pressing device which laminates the multilayer continuous web by exerting a compressive force. The pressing device has a pressing surface with at least one outwardly projecting elevation, which is arranged such that when the compressive force is exerted, it comes into contact with a portion of the continuous web which adjoins an edge side of the electrode.

  • Publication number: 20260128273
    Abstract: The invention relates to a laminating apparatus for a multilayer endless web, which is made of at least one separator web and at least one electrode, for producing energy cells, comprising a pressing device which laminates the multilayer endless web while exerting a compressive force. The pressing device has a pressing surface with at least one recess which is arranged such that when the compressive force is being exerted via the pressing surface, the recess overlaps with at least one of the edges of the electrodes.

  • Publication number: 20260081135
    Abstract: The invention relates to a laminating apparatus for a multilayer continuous web composed of at least one separator web and at least one electrode for producing energy cells, with a pressing device which laminates the multilayer continuous web by exerting a compressive force, wherein the pressing device has two pressing surfaces, with which it comes into contact with different sides of the continuous web, and the pressing surfaces are temperature-controlled differently.
