Title
(DE) VERFAHREN ZUM TRENNEN BANDFÖRMIGEN ELEKTRODEN- UND SEPARATORMATERIALS AUF EINER GEKRÜMMTEN OBERFLÄCHE UNTER VERWENDUNG EINES LASERSTRAHLES
(EN) METHOD FOR CUTTING STRIP-SHAPED ELECTRODE AND SEPARATOR MATERIAL ON A CURVED SURFACE BY MEANS OF A LASER BEAM

Abstract
(DE)
Die Erfindung bezieht sich auf eine Vorrichtung zum Abtrennen von Abschnitten (70) von bandförmigem Material (66, 82), welches als Spulenvorrat (140) vorliegt. Ein angetriebenes Rad (92) ist in Umfangsrichtung in einzelne Umfangssegmente unterteilt. Diese sind entweder Vakuum beaufschlagt oder mit Blasluft beaufschlagt. Der Umfangsflache (94) des angetriebenen Rades (92) ist ein Laser (96) zugeordnet, der einen auf einem der Umfangssegmente fixierten Abschnitt (70) vom bandförmigen Material (66, 82) abtrennt.
(EN)
The invention relates to a device for cutting off portions (70) of strip-shaped material (66, 82), which is in the form of a reel stock (14). A driven wheel (92) is divided into individual circumferential segments in the circumferential direction. Either vacuum or blowing air is applied to said individual circumferential segments. A laser (96) is associated with the circumferential surface (94) of the driven wheel (92), which laser cuts off a portion (70) of the strip-shaped material (66, 82), which portion is fixed on one of the circumferential segments.
(FR)
L'invention concerne un dispositif pour séparer des tronçons (70) d'un matériau (66, 82) en forme de bande se présentant sous la forme d'un stock en bobine (140). Une roue (92) entraînée est divisée en segments périphériques individuels dans la direction périphérique. Ceux-ci sont soumis soit au vide, soit à un air de soufflante. A la surface périphérique (94) de la roue (92) entraînée est associé un laser (96) qui sépare un tronçon (70) fixé sur un des segments périphériques du matériau (66, 82) en forme de bande.
