Title (EN) PROCESS FOR SHREDDING TOBACCO STEMS
(FR) PROCEDE DE DEFIBRAGE DE COTES DE TABAC
Abstract: front page image
(EN)The processing of tobacco stems in cigarette making has been complicated in the past because of the structural dissimilarity of the rod-like stems in comparison with the laminar portions of the tobacco leaf. This invention provides a solution to this problem by a process for shredding tobacco stems so they are structurally compatible with the laminar portions of the tobacco leaf. The process comprises the shredding of tobacco stems by splitting or parting the stems along the grain to produce light, pliable, low bulk density fibrillar shreds. Stems shredded according to the present process exhibit sufficient resiliency so that when massed they approximate or exceed the filling capacity of cut leaf shreds. Apparatus utilizing blunt rotatable blade-like elements (20 or 34) are also disclosed.
(FR)Le procede de defibrage de cotes de tabac dans la fabrication de cigarettes s"est avere complique dans le passe a cause de la difference de structure entre les cotes en forme de batonnets et les parties laminaires de la feuille de tabac. La solution de ce probleme est un procede de defibrage des cotes de tabac de maniere a rendre leur structure compatible avec les parties laminaires de la feuille de tabac. Le procede consiste a defibrer les cotes de tabac en fendant ou divisant les cotes dans le sens du grain pour produire des filaments fibreux legers, pliables, de faible densite. Les cotes defibrees selon ce procede presentent une souplesse suffisante pour que, une fois compactees elle approchent ou depassent la capacite de remplissage des cotes de feuilles coupees. Un appareil utilisant des elements en forme de couteaux rotatifs emousses (20 ou 34) est egalement decrit.
