Claims (10)

  1. Verfahren zur Herstellung von Filterelementen (7) für aerosolgenerierende Produkte (1), insbesondere Filterstückelementen (7) für Rauchartikel, umfassend:
    Verarbeiten von Massenfiltermaterial (8), um einen im Wesentlichen kontinuierlichen Strang (D) des Filtermaterials (8) bereitzustellen oder zu bilden; und
    Bedecken des im Wesentlichen kontinuierlichen Strangs (D) von Filtermaterial (8) mit mindestens einer Schicht (9) eines Bahnmaterials, um ein längliches Filterelement (R, 20) zu bilden;
    wobei das Verfahren den Schritt umfasst, Perforationen oder Löcher (17) in dem länglichen Filterelement (R, 20) zu bilden, indem die Perforationen oder Löcher (17) in der mindestens einen Schicht (9) eines Bahnmaterials und in oder durch das Filtermaterial (8), das durch die mindestens eine Schicht (9) eines Bahnmaterials bedeckt oder umhüllt wird, nach dem Schritt des Bedeckens des Strangs (D) von Filtermaterial (8) mit der mindestens einen Schicht (9) eines Bahnmaterials ausgebildet werden, dadurch gekennzeichnet, dass das Verfahren ein Verfahren zur Herstellung diskreter oder individueller Filterelemente (7) ist.
  2. Verfahren nach Anspruch 1, wobei das längliche Filterelement (R, 20) einen im Wesentlichen kontinuierlichen Filterstab (R) oder ein Filterstabelement (20) einer zuvor festgelegten Länge umfasst, und wobei das Verarbeiten Folgendes umfasst:
    Schneiden des kontinuierlichen Filterstabes (R) oder des Filterstabelements (20) von zuvor festgelegter Länge in mehrere diskrete oder individuelle Filterelemente (7), von denen jedes dafür ausgebildet ist, mit einem jeweiligen Stabelement (2) aus aerosolerzeugendem Material (3), wie beispielsweise Tabak, zu einem Rauchartikel (1) zusammengesetzt zu werden, wobei der Schritt des Bildens der Perforationen oder Löcher (17) in der Schicht (9) aus Bahnmaterial vor dem Schneideschritt durchgeführt wird.
  3. Verfahren nach Anspruch 1, wobei das längliche Filterelement (R, 20) einen kontinuierlichen Filterstab (R) umfasst, wobei das Verarbeiten Folgendes umfasst: Schneiden des kontinuierlichen Filterstabes (R) in mehrere längliche Stabelemente (20) von zuvor festgelegter Länge, wobei der Schritt des Bildens von Perforationen oder Löchern (17) in der Schicht (9) aus Bahnmaterial an den länglichen Stabelementen (20) durch- oder ausgeführt wird.
  4. Verfahren nach einem der vorangehenden Ansprüche, wobei die Perforationen oder Löcher (17) zufällig in der Schicht (9) aus Bahnmaterial ausgebildet oder angeordnet sind, oder wobei die Perforationen oder Löcher (17) gleichmäßig oder regelmäßig in der Schicht (9) ausgebildet oder angeordnet sind.
  5. Verfahren nach einem der vorangehenden Ansprüche, wobei die Perforationen oder Löcher (17) um einen Umfang des kontinuierlichen Filterstabes (R) oder der länglichen Stabelemente (20) herum angeordnet oder ausgebildet sind, und/oder wobei die Perforationen oder Löcher (17) in Längsrichtung entlang des kontinuierlichen Filterstabes (R) oder der länglichen Stabelemente (20) angeordnet oder ausgebildet sind.
  6. Verfahren nach einem der vorangehenden Ansprüche, wobei der Schritt des Bildens von Perforationen oder Löchern (17) in der Schicht (9) aus Bahnmaterial das Bewegen des kontinuierlichen Filterstabes (R) oder der länglichen Stabelemente (20) relativ zu einer Perforationsvorrichtung oder einer Lochbildungsvorrichtung (40) umfasst, vorzugsweise das Drehen des Filterstabes (R) oder der länglichen Stabelemente (20) um eine Längsachse derselben.
  7. Verfahren nach einem der vorangehenden Ansprüche, wobei der Schritt des Bildens von Perforationen oder Löchern (17) das Bestrahlen der Schicht (9) aus Bahnmaterial mit mindestens einem Laserstrahl umfasst, wodurch die Perforationen oder Löcher (17) mit dem mindestens einen Laserstrahl gebildet werden.
  8. Verfahren nach Anspruch 7, wobei der mindestens eine Laserstrahl relativ zu dem Filterstab (R) oder den Filterstabelementen (20) beweglich ist, vorzugsweise entlang einer Längsrichtung und/oder in einer Querrichtung relativ dazu.
  9. Verfahren nach einem der vorangehenden Ansprüche, wobei eine Perforationsvorrichtung oder Lochbildungsvorrichtung (40) umfasst: eine Laserquelle, eine Strahlteileranordnung zum Erzeugen mehrerer Laserstrahlen aus der Laserquelle, mehrere Lichtleitfasern zum Transportieren und Richten eines jeweiligen Laserstrahls auf den Filterstab (R) oder die Filterstabelemente (20) und einen Lichtwellenleiterträger, der dafür ausgebildet ist, ein freies Ende jeder der Lichtleitfasern so aufzunehmen und zu halten, dass die Laserstrahlen von jeder einzelnen Lichtleitfaser neben und in Richtung der Schicht (9) aus Bahnmaterial, die den Filterstab (R) oder die Filterstabelemente (20) bedeckt, angeordnet sind.
  10. Verfahren nach einem der vorangehenden Ansprüche, des Weiteren umfassend folgenden Schritt:
    Schneiden des langgestreckten Filterelements (R, 20) in mehrere diskrete oder individuelle Filterelemente (7), von denen jedes zur Montage an einem Element (2) aus aerosolerzeugendem Material (3), insbesondere einem Stabelement aus Tabak, ausgebildet ist;
    wobei das Filtermaterial (8) Celluloseacetatwerg umfasst, und
    wobei die Schicht (9) aus Bahnmaterial porös oder nichtporös ist und vorzugsweise Papier umfasst.
