Abstract

Process for producing a package made of a one-piece blank (2) with a tear-open aid in the form of a tear-open thread (3) provided on the inside, this tear-open aid running in a slightly angled manner in relation to the edges of the blank. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen einer Verpackung, insbesondere aus einem einteiligen Zuschnitt mit einer an der Innenseite vorgesehenen Aufreißhilfe in Form eines Aufreißfadens od.dgl.The invention relates to a method for producing a package, in particular from a one-piece blank with a tear aid provided on the inside in the form of a tear thread or the like.

Aufreißfäden od dgl. Aufreißhilfen haben sich bei einer Vielzahl von Verpackungen bewährt. Ihre beiden Enden laufen in der Längsnaht zusammen, wodurch ein Ende frei erfaßbar ist. Beim Herstellen dieser Längsnaht, die als Siegelnaht ausgebildet ist, ergeben sich jedoch durch die Verdoppelung der Aufreißhilfe beträchtliche Schwierigkeiten.Tear-off threads or the like. Tear-off aids have proven themselves in a large number of packagings. Both ends converge in the longitudinal seam, whereby one end is freely graspable. When producing this longitudinal seam, which is designed as a sealed seam, there are considerable difficulties in doubling the tear-open aid.

Der Erfindung liegt daher die Aufgabe zugrunde, die Aufreißhilfe so anzuordnen, daß eine Materialanhäufung verhindert wird.The invention is therefore based on the object of arranging the tear-open aid in such a way that an accumulation of material is prevented.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Aufreißhilfe gegenüber den Kanten des Zuschnittes geringfügig schräg verläuft.This object is achieved in that the tear aid runs slightly obliquely with respect to the edges of the blank.

Dadurch kommen die beiden Enden der Aufreißhilfe nebeneinander und nicht übereinander zu liegen, so daß keine nachteilige Beeinflussung beim Herstellen der Längssiegelnaht eintritt.As a result, the two ends of the tear-open aid come next to one another and do not lie one above the other, so that there is no adverse influence on the production of the longitudinal sealing seam.

Sehr vorteilhaft ist es auch, wenn erfindungsgemäß die Aufreißhilfe in Maschinenrichtung auf dem die Zuschnitte enthaltenden Kartonbogen od.dgl. aufgebracht wird, während die Zuschnitte geringfügig verdreht auf dem Kartonbogen od.dgl. angeordnet werden.It is also very advantageous if, according to the invention, the tear-open aid or the like in the machine direction on the cardboard sheet containing the blanks. is applied while the blanks are slightly twisted or the like on the cardboard sheet. to be ordered.

Dadurch ist eine sehr rationelle Herstellung der mit der Aufreißhilfe versehenen Zuschnitte ermöglicht.This enables a very efficient production of the blanks provided with the tear-open aid.

Es hat sich als völlig ausreichend ergeben, wenn erfindungsgemäß die Aufreißhilfe und die Kanten des Zuschnittes mit einem Winkel von etwa 1° gegeneinander verdreht verlaufen.It has been found to be completely sufficient if, according to the invention, the tear-open aid and the edges of the blank are rotated relative to one another at an angle of approximately 1 °.

In der Zeichnung ist die Erfindung anhand eines Ausführungsbeispieles veranschaulicht. Die Figur zeigt einen Ausschnitt eines Kartonbogens, auf dem zwölf Zuschnitte vorgesehen sind.The invention is illustrated in the drawing using an exemplary embodiment. The figure shows a section of a cardboard sheet on which twelve blanks are provided.

Mit 1 ist ein Kartonbogen bezeichnet, auf dem zwölf gleiche Zuschnitte 2 vorgesehen sind, die zum Herstellen einer Kartonverpackung dienen. Diese Zuschnitte 2 sind gegenüber den Kanten des Kartonbogens 1 um 1° verdreht angeordnet. Über jede Reihe dieser Zuschnitte 2 verläuft ein Aufreißfaden 3, der parallel zu den Außenkanten des Kartonbogens 1 und damit in Maschinenrichtung verläuft. Mit den Kanten bzw. Faltlinien der einzelnen Zuschnitte 2 schließt er dagegen den Winkel von 1° ein.1 designates a cardboard sheet on which twelve identical blanks 2 are provided, which are used to produce cardboard packaging. These blanks 2 are arranged rotated by 1 ° with respect to the edges of the cardboard sheet 1. A tear thread 3 runs over each row of these blanks 2 and runs parallel to the outer edges of the cardboard sheet 1 and thus in the machine direction. With the edges or fold lines of the individual blanks 2, however, it encloses the angle of 1 °.
