Abstract

Procédé de perforation de cigarette permet d'obtenir un taux de ventilation réglable. Le procédé comprend les étapes suivantes : S1, préformer des premiers trous traversants dans du papier d'emballage, de façon à former une première zone de ventilation ; S2, préformer des seconds trous traversants dans du papier manchette et former une rainure fonctionnelle tous les deux seconds trous traversants, de façon à former une zone déchirable ; S3, lorsqu'une cigarette est préparée, envelopper le papier manchette autour du papier d'emballage et amener la zone déchirable à recouvrir un côté externe de la première zone de ventilation ; et S4, réaliser une perforation en ligne sur la cigarette et former des trous de ventilation de référence dans le papier manchette et le papier d'emballage pour former une seconde zone de ventilation. Le procédé de perforation de cigarette est simple et pratique. Le papier d'emballage et le papier manchette sont pré-perforés pour former une première zone de ventilation, qui peut être créée au moyen d'une déchirure, et la première zone de ventilation coopère avec une seconde zone de ventilation, qui est formée au moyen de la réalisation d'une perforation en ligne sur une cigarette ; et un fumeur peut déchirer une zone déchirable, ce qui permet de modifier le taux de ventilation de la cigarette et d'améliorer l'expérience de tabagisme du fumeur. De plus, lorsque la cigarette est préparée, la zone déchirable est dans un état non déchiré, de telle sorte que la stabilité de la production de cigarette n'est pas affectée, ce qui permet d'obtenir une bonne applicabilité.
