Description

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen von Ventilsäcken mit Innensack nach dem Oberbegriff des Patentanspruchs.The invention relates to a method for producing valve bags with an inner bag according to the Generic term of the claim.
Bei einem bekannten Verfahren zur Herstellung von sogenannten genähten Flachsäcken (US-PS 30 94 083) wird ein lediglich bodenseitige Quernähte aufweisender Folienschlauch mit den Werkstoffbahnen für die Umsäcke unabgelängt zusammengeführt. Dann werden die Werkstoffbahnen als Schlauch um den Folienschlauch geformt, gemeinsam abgelängt und anschließend durch Nähen unterhalb der Schweißnaht miteinander verbunden.In a known method for the production of so-called sewn flat sacks (US-PS 30 94 083) a film tube with the material webs for the Bags brought together without being cut to length. Then the material webs are used as a tube around the film tube shaped, cut to length together and then sewn together below the weld seam tied together.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Herstellen eines geklebten Ventilsacks mit Innensack zu entwickeln, welches eine durchgehend mechanisierte Herstellung zuläßt.The invention is based on the object of a method for producing a glued valve bag to be developed with an inner sack, which allows a completely mechanized production.
Das erfindungsgemäße Verfahren zeichnet sich durch die Merkmale des kennzeichnenden Teils des Patentan-Spruchs aus.The method according to the invention is characterized by the features of the characterizing part of the patent claim the end.
Damit ist die vollmechanisierte Fertigung eines Ventilsacks mit Innensack erreicht, bei dem dieser beidendig Quernähte trägt und der Umsack beidendig durch eine Kreuzbodenfaltung geschlossen ist. Die Faltungsbewegung des Kreuzbodens ist durch den Innensack nicht behindert. Die Einschnittöffnung im Innensack schafft einen Luftdurchlaß im sonst beidendig verschlossenen Innensack. Mit seinen angehefteten Zonen folgt der Innensack bereitwillig der Kreuzbodenfaltung des Umsacks, wobei die Einschnittöffnung den dazu erforderlichen Luftaustausch regelt. Um nicht gegen den Eckeinschlag zu blasen, ist eine Versetzung des Einschnitts gegenüber dem Rand des Eckeinschlags zur Schlauchmitte des Umsacks bedeutungsvoll. Wegen der abgestimmten Faltung des I Imsackbodens bezüglich des daran gehefteten Innensacks gelangt der Einschnitt des Innensacks von selbst in eine ordnungsgemäße Lage, wie sie zu Füllzwecken und zur Lagerung der gefüllten Säcke erwünscht ist.This achieves the fully mechanized production of a valve bag with an inner bag in which this wears transverse seams at both ends and the bag is closed at both ends by a cross-bottom fold. the The inner sack does not hinder the folding movement of the cross bottom. The incision opening in the Inner bag creates an air passage in the inner bag, which is otherwise closed at both ends. With his pinned Zones, the inner sack readily follows the cross-bottom fold of the outer sack, whereby the incision opening denotes the regulates the air exchange required for this. In order not to blow against the corner impact, there is an offset of the incision opposite the edge of the corner fold to the middle of the tube of the bag is significant. Because The incision arrives at the coordinated folding of the bottom of the sack with respect to the sack attached to it of the inner sack by itself in a proper position, such as for filling purposes and for storage of the filled sacks is desirable.

Der in F i g. 1 dargestellte Sack umfaßt einen Umsack 10 aus einer oder mehreren Lagen Papier oder dergleichen und einen Innensack 11, der von einem beidendig Quernähte 12 aufweisenden Abschnitt eines Folienschlauches, beispielsweise aus Polyäthylen, gebildet ist. Die Böden 13 des Umsacks 10 sind als Kreuzboden gestaltet.The in F i g. 1 illustrated sack comprises a bag 10 made of one or more layers of paper or The like and an inner bag 11, which is of a section having transverse seams 12 at both ends Foil tube, for example made of polyethylene, is formed. The bottoms 13 of the bag 10 are as Cross bottom designed.
Für die Fertigung der Säcke werden ein Folienschlauch aus Polyäthylen und die die Säcke bildenden Bahnen aus Papier zusammengeführt, aneinandergeheftet und gemeinsam abgelängt, nachdem der Folienschlauch auch mit den die Innensackenden bildenden Quernähten und den Einschnitten versehen wurde. Die Quernäh'e hegen mit geringem Abstand paarig nebeneinander, von denen eine das Bodenende und die andere das Kopfende des späteren Innensacks 11 bildet. Der Einschnitt ist längsgerichtet, hat eine der halben Breite des Sackbodens 13 entsprechende Länge und geht von einer der beiden Quernähte aus, nämlich jener, die das spätere Kopfende des Innensacks 11 bildet. Die Einschnitte sind in einer Zone des Folienschlauchs angeordnet, die gegen den Rand des ventilbildenden Eckeinschlags des Kreuzbodens 13 zur Mitte der Sackbreite geringfügig, beispielsweise um 2 cm, versetzt sind. Im dargestellten Ausführungsbeispiel von Fig.4 ist die mit einem solchen Einschnitt 18 versehene kopfseitige Quernaht 12 auf jenen Breitenbereich des Kreuzbodens beschränkt, der zwischen dem Einschnitt 18 und dem vom ventilbildenden Eckeinschlag 15 abgewandten Längsrand des Sacks liegt. Am anderen Ende ist der Innensack mit einer durchlaufenden, nicht näher gezeigten Quernaht geschlossen, die keinen Einschnitt besitzt. Die Bahnen zur Bildung der Umsäcke 10 werden vor ihrem Zusammenführen in denjenigen Zonen mit Klebstoffaufträgen 14 zum Anheften des Folienschlauchs versehen, die jeweils dem Rand des zu bildenden Umsack-Kreuzbodens 13 benachbart sind. Die Bahnen für die Umsäcke 10 werden über dem Folienschlauch zu einem diesen umhüllenden weiteren Schlauch geformt, und es entsteht eine Haftverbindung zwischen dem Folienschlauch und der Innenfläche des umhüllenden Schlauches. Anschließend wird der Schlauch in Abschnitte zerlegt, wobei die TrennlinienFor the production of the sacks, a film tube made of polyethylene and that of the sacks are used Sheets of paper merged, stapled together and cut to length after the film tube was also provided with the transverse seams and the incisions forming the inner sack ends. the Cross seams lie in pairs next to each other at a small distance, one of which is the bottom end and the other forms the head end of the later inner bag 11. The incision is longitudinal, has a length and half the width of the bag bottom 13 corresponding is based on one of the two transverse seams, namely that which later forms the head end of the inner bag 11. the Incisions are arranged in a zone of the film tube, which is against the edge of the valve-forming Corner impact of the cross base 13 to the center of the bag width slightly, for example by 2 cm, offset are. In the illustrated embodiment of Figure 4 is the head-side transverse seam 12 provided with such an incision 18 to that width area of the Cross bottom limited between the incision 18 and the valve-forming corner impact 15 facing away from the longitudinal edge of the sack. At the other end is the inner bag with a continuous, no Transverse seam shown in more detail closed, which has no incision. The tracks for the formation of the bags 10 are before they are brought together in those zones with adhesive applications 14 for attaching the Provided film tube, which are each adjacent to the edge of the Umsack-Kreuzboden 13 to be formed. The webs for the bags 10 become a further enveloping one above the film tube Tubing is formed, and an adhesive bond is created between the film tube and the inner surface of the enveloping hose. The hose is then divided into sections, with the dividing lines
