Abstract
(DE)
Aus einem einstückigen Zuschnitt wird ein Kartonbehälter (7) mit einem oberen Bördelrand (25) hergestellt. Dabei wird ein zur Behälteraussenseite umgelegter, einfacher oder doppelter Bördelrand durch einmaliges oder zweimaliges Umlegen von Randstreifen am noch flachliegenden Zuschnitt maschinell in aufeinanderfolgenden Schritten einschliesslich Verklebung ausgebildet und dann erst die räumliche Behälterform maschinell durch Zusammenkleben der umgelegten Seitenwände hergestellt. Der Bördelrand verleiht dem Behälter die erforderliche Formstabilität bei Verwendung von Zuschnitt-Material mit einem erheblich geringeren Kartongewicht im Vergleich zu bisher verwendeten Behältern gleicher Grösse ohne Bördelrand.
(EN)
A cardboard box (7) with a flanged top edge (25) can be made from a one-piece cut-out. A single or double flanged edge folded around the outside of the box is produced by a machine which folds down and glues an edge strip on the flat cut-out once or twice in consecutive steps. The three-dimensional box shape is obtained by folding down the side walls and gluing them together. The flanged edge confers the necessary dimensional stability on the box made of cut-out material and the box is considerably lighter than conventional boxes of similar size with no flanged edge.
(FR)
On peut fabriquer un récipient de carton (7) doté, en sa partie supérieure, d'un collet rabattu (25) à partir d'une seule pièce découpée. On forme un collet rabattu simple ou double, replié vers l'extérieur du récipient, en repliant une ou deux fois des bandes latérales prévues sur la pièce découpée; cette opération mécanique se fait en plusieurs étapes successives, y compris le collage; c'est ensuite seulement que l'on donne au récipient sa forme tridimensionnelle en collant mécaniquement les unes aux autres les parois latérales repliées. Le collet rabattu confère au récipient sa stabilité de forme, ce qui permet d'utiliser pour la pièce découpée un carton beaucoup plus léger que pour les récipients de même format sans collet rabattu qui se faisaient jusqu'à présent.
