Abstract
(DE)
Die Erfindung betrifft ein System (10) zum Transportieren eines Folienschlauches (2) einer Blasfolienanlage (1) entlang einer Transportrichtung aufweisend eine Leiteinheit (51) zum Leiten des Folienschlauches (2), eine Engstelle (13.1), an welcher eine Breite (2.3) des Folienschlauches (2) reduzierbar ist, eine Durchtrennvorrichtung (20) mit zumindest einem Durchtrennelement (21) zum Durchtrennen des Folienschlauches (2), wobei die Leiteinheit (51) der Engstelle (13.1) in der Transportrichtung des Folienschlauches (2) nachgeordnet ist. Ferner betrifft die Erfindung eine Blasfolienanlage (1), sowie ein Verfahren (100) zur Herstellung einer Folie.
(EN)
The invention relates to a system (10) for transporting a film tube (2) in a blown film line (1) along a transport direction, having a guiding unit (51) for guiding the film tube (2), a bottleneck (13.1) at which a width (2.3) of the film tube (2) can be reduced, a severing apparatus (20) having at least one severing element (21) for severing the film tube (2), wherein the guiding unit (51) is arranged downstream of the bottleneck (13.1) in the transport direction of the film tube (2). The invention furthermore relates to a blown film line (1) and to a method (100) for producing a film.
(FR)
L'invention concerne un système (10) pour transporter une feuille tubulaire (2) d'une installation pour feuilles soufflées (1) le long d'une direction de transport, comprenant une unité de guidage (51) pour guider la feuille tubulaire (2), un rétrécissement (13.1) auquel une largeur (2. 3) de la feuille tubulaire (2) peut être réduit, un dispositif de sectionnement (20) comportant au moins un élément de sectionnement (21) pour sectionner la feuille tubulaire (2), l'unité de guidage (51) étant disposée en aval du rétrécissement (13.1) dans la direction de transport de la feuille tubulaire (2). L'invention concerne également une installation pour feuilles soufflées (1) et un procédé (100) pour produire une feuille.
