Abstract (en)
[origin: WO2013050088A1] The invention relates to a method for cutting sheet-shaped or plate-shaped objects (1) having thermoplastic synthetic fibres as substrate material, in particular electrodes and/or separators for the construction of an electrochemical energy accumulator or parts of such electrodes or separators, said method including the steps of: (S1) guiding the objects (1) to be cut towards a laser cutting device (2), and (S2) cutting the objects (1) with the laser cutting device (2) in such a way that a fusion of at least some of the thermoplastic synthetic fibres is carried out on the cut edges (3). The invention further relates to a system (10) for cutting sheet-shaped or plate-shaped objects (1) having thermoplastic synthetic fibres as substrate material, in particular for cutting electrodes and/or separators for the construction of an electrochemical energy accumulator or parts of such electrodes or separators, wherein the cutting system (10) includes a transport device (5), which is configured for guiding the objects (1) to be cut towards a laser cutting device (2), and a laser cutting device (2) which is configured for cutting the objects (1) such that a fusion of at least some of the thermoplastic synthetic fibres is performed on the cut edges (3).
