Abstract

La présente invention concerne un support pour un matériau surfacique fragile particulièrement adapté à la découpe dudit matériau en feuille au moyen d'un fluide dont le flux est dirigé vers le plan à découper. Le support comporte des parties pleines constituées en un matériau résistant et qui délimitent entre elles des parties vides ou maillées. La partie la plus étroite de la section des mailles n'est que légèrement supérieure à la partie la plus large de la section du flux de fluide dans sa traversée du support. Le support peut être utilisé notamment pour la découpe de capes pour cigares dans des feuilles de tabac.
