A process for manufacturing an active substance-containing product from strip tape. A broad web material roll is mounted, loosely rotatable, on a take-up mandrel. The web of material is drawn, in its entire width and without tensile stress, from the roll of material by a vacuum roll, and is separated into individual strips in the negative pressure zone of the vacuum roll by rolling a multiple circular knife roll. At the end of the negative pressure zone of the vacuum roll, each strip is drawn from the vacuum roll and is introduced in a take-up channel and continuously conveyed by negative pressure. Each strip is turned on its way to or through the channel by about 90°. At the end of the channels the strips are led at least two at a time, and conveyed further in a groove for further processing to form the finished product.
L'invention concerne un procédé permettant de préparer un produit, en particulier un produit se caractérisant en ce que : un rouleau de matériau (1, 2) est emboîté de manière à tourner librement, sur un mandrin de réception (3) ; la bande de matériau (2) est prélevée à l'aide d'un rouleau à vide (4) sans induire d'effort de traction de la part du rouleau de matériau (1) et est répartie en bandes (6) individuelles par déroulement d'un rouleau à lames rotatives multiples (5) ; chaque bande (6) est introduite dans un canal de réception (7) à l'intérieur duquel elle est acheminée en continu au moyen de vide partiel. A cet effet, chaque bande (6) subit une rotation d'approximativement 90 DEG .
