Abstract
(DE)
Die Erfindung betrifft ein System (10) zur verbesserten Einführung einer Trennvorrichtung (40) in einen flachgelegten Folienschlauch (2) einer Blasfolienanlage (1), mit einer Schneidevorrichtung (20) zur Durchtrennung von lediglich einer ersten Schlauchseite (2.1) des Folienschlauches (2), insbesondere des noch nicht flachgelegten Folienschlauches (2). Ferner betrifft die Erfindung eine Blasfolienanlage (1), sowie ein Verfahren (100) zur Herstellung und Bereitstellung von zumindest zwei Folienbahnen (6).
(EN)
The invention relates to a system (10) for the improved introduction of a separating device (40) into a laid-flat film tube (2) of a blown film line (1), with a cutting device (20) for the severing of only a first tube side (2.1) of the film tube (2), in particular of the film tube (2) which has not yet been laid flat. Furthermore, the invention relates to a blown film line (1), and to a method (100) for the production and provision of at least two film webs (6).
(FR)
L'invention concerne un système (10) pour l'introduction améliorée d'un dispositif de séparation (40) dans un boyau de film aplati (2) d'une ligne d'extrusion-soufflage (1), comprenant un dispositif de coupe (20) destiné à sectionner seulement un premier côté de boyau (2.1) du boyau de film (2), notamment du boyau de film (2) pas encore aplati. L'invention concerne en outre une ligne d'extrusion-soufflage (1), ainsi qu'un procédé (100) de production et de fourniture d'au moins deux bandes de film (6).
