Handling sensitive material with ease


GOEBEL IMS sets new standards in processing battery separator film

The markets for renewable energy and high-performance Li-ion batteries are consistently growing. Therefore, the demand for bi-axially oriented specialty film rapidly increases. Battery separator films play an important role in Li-ion battery technology. During the charging and discharging cycles, the ions move from cathode to anode and back. Thereby they pass the microporous separator film which physically separates and electrically isolates cathode from anode. To ensure that the film surface won’t get damaged a sensitive processing is required. Thus, the highest quality is the key to success.

For converting battery separator films, GOEBEL IMS developed the ultimate slitter rewinder INTERSLIT BSF. The cutting-edge machine is specifically designed to process hyper sensitive materials such as battery separator film also based on wet-process BOPE. To ensure the best results, the innovative slitter rewinder offers several state-of-the-art features and options. The especially compact station rewinder concept with a short web path from unwind to rewind keeps the web on track and allows lowest web tension ranges. Thanks to the ergonomic design, the machine is functionally accessible all-around and thereby ensures highest productivity during unloading and set-up.

When it comes to quality, GOEBEL IMS follows a no compromise policy. To guarantee best results, the developing engineers focused on achieving the maximum of precision and efficiency. Therefore, high end components such as all carbon fiber and individually driven rollers, as well as an absolute precise and sensitive web tension control system, are integrated in the INTERSLIT BSF to ensure the proper handling of such valuable and delicate substrate like BOPE based battery separator film. To achieve the targeted finished roll quality, the contact force is individually adjustable from gap winding up to sensitive contact winding. All finished rolls are carefully rewound on individual rewind stations which are positioned fully automatic and are all arranged on one common side of the slitter rewinder. These stations open automatically and release the finished rolls into a rest position, where the operator or optionally an automatic handling system will clear the rolls from the unloading position. Thus, an easy and fast unloading and inspection of the finished rolls is guaranteed.

To achieve the maximum of efficiency, the INTERSLIT BSF is tailor-made for every customer. It provides a maximum web width of up to 6,000 mm while unwind and rewind diameter as well as speed are adjusted upon customers’ needs. The top solution for most precise and dust reduced cutting are individual driven shear top knifes which are embedded in a carbon fiber body bottom cutter shaft that also can be driven independently. Alternatively, classical razor blade holders would apply. Additionally, knife de-dusting systems and double side web-cleaning devices downstream the unwinding unit are available.

All benefits of the INTERSLIT BSF at a glance:

  • Modular configuration for customer-specific applications
  • Unique “All-driven concept” for most precise web tension control
  • Shortest web path between unwinding and rewinding
  • Super compact and ergonomic machine design
