Title
(DE) VERFAHREN UND VORRICHTUNG FÜR EINE KONTROLLE EINES RANDABSCHNITTS EINER FOLIENBAHN
(EN) METHOD AND DEVICE FOR MONITORING AN EDGE SECTION OF A FILM WEB
(FR) PROCÉDÉ ET DISPOSITIF POUR CONTRÔLER UNE PARTIE MARGINALE D’UNE BANDE CONTINUE
Abstract
(DE)
Die Erfindung betrifft ein Verfahren für eine Kontrolle eines Randabschnitts (RA) einer Folienbahn (FB) in einer Flachfolienmaschine (100), aufweisend die folgenden Schritte: - Erfassen eines Dickenprofils (DP) in wenigstens einem Randabschnitt (RA) der Folienbahn (FB) in einer Querrichtung (QR) quer zur Produktionsrichtung (PR) der Folienbahn (FB), - Vergleich zumindest eines Teilabschnitts des erfassten Dickenprofils (DP) des Randabschnitts (RA) mit einem Vorgabeprofil (VP), - Bestimmen einer Profilabweichung (PA) als Ergebnis des Vergleichs, - Durchführen eines Kontrolleingriffs an der Flachfolienmaschine (100) auf Basis der bestimmten Profilabweichung (PA).
(EN)
The invention relates to a method for monitoring an edge section (RA) of a film web (FB) in a flat film machine (100), having the following steps: - sensing a thickness profile (DP) in at least one edge section (RA) of the film web (FB) in a transverse direction (QR) transverse to the production direction (PR) of the film web (FB), - comparing at least a portion of the thickness profile (DP) of the edge section (RA) sensed with a reference profile (VP), - determining a profile deviation (PA) as a result of the comparison, - performing a control intervention on the flat film machine (100) on the basis of the profile deviation (PA) determined.
(FR)
L’invention concerne un procédé permettant de contrôler une partie marginale (RA) d’une bande continue (FB) dans une machine à produire des feuilles plates (100), ledit procédé comportant les étapes suivantes : détecter un profil d’épaisseur (DP) dans au moins une partie marginale (RA) de la bande continue (FB), dans une direction transversale (QR) transversalement à la direction de production (PR) de la bande continue (FB), comparer au moins un segment partiel du profil d’épaisseur (DP) détecté du segment marginal (RA) avec un profil par défaut (VP), déterminer un écart de profil (PA) comme résultat de la comparaison, effectuer une opération de contrôle sur la machine à produire des feuilles plates, sur la base de l’écart de profil (PA) déterminé.
