Dans un procédé de formation de boudins dans une machine à boudins (120), du tabac particulaire est dispersé sur une bande aspirante (17) dans un canal de guidage de boudins (16) ayant une section transversale réglable, le tabac dispersé est égalisé sur la bande aspirante (17) dans le canal de guidage de boudins (16) au moyen d'un dispositif de raclage (19) délimitant une hauteur du canal de guidage de boudins (16). Ensuite, un boudin de tabac est formé en enveloppant le tabac égalisé avec une bande de matériau d'enveloppement et en découpant à l'aide d'un dispositif de coupe (31) des produits en forme de tiges à partir du boudin de tabac et en les traitant sous la forme d'une rangée monocouche de produits en forme de tiges dans une machine de traitement ultérieur (130). Selon l'invention, la bande de matériau d'enveloppement contient un matériau imperméable aux micro-ondes ou se compose d'un matériau imperméable aux micro-ondes et après réception d'un signal d'échantillonnage (135), un échantillon d'un ou de plusieurs produits en forme de tiges est sorti d'une rangée monocouche de produits en forme de tiges et pesé au moyen d'un dispositif de pesage (150).
