Die Herstellung von Ventilsäcken, die einen aus einem Ventilblatt gebildeten Ventilschlauch aufweisen, der in eine bei der Faltung des Bodens des Ventilsacks gebildete Ventilöffnung eingesetzt wird, ist in zahlreichen Ausführungsformen bekannt. Der Boden mit dem eingesetzten Ventilschlauch wird im Allgemeinen durch ein aufgeklebtes rechteckiges Bodendeckblatt abgedeckt und gesichert.The Production of valve bags, having a valve tube formed from a valve sheet, in a formed in the folding of the bottom of the valve bag valve opening is used, is known in numerous embodiments. The floor with the valve tube used is generally by a glued rectangular ground cover sheet covered and secured.
Der Ventilschlauch kann dabei innerhalb der Ventilöffnung, also unterhalb des Bodendeckblatts verbleiben. In diesem Fall spricht man von einem Innenventil. Ragt der Ventilschlauch nur ein kleines Stück aus der Ventilöffnung heraus, spricht man von einem Stummelventil. Ein Ventilschlauch, der sich über die Seitenfaltenkante des die Sackwandung bildenden, flachgelegten Materialschlauchs hinaus erstreckt, wird als Außenventil bezeichnet.Of the Valve tube can thereby within the valve opening, ie below the Ground cover leaves remain. In this case one speaks of one Internal valve. The valve hose protrudes only a small piece from the valve opening out, one speaks of a stub valve. A valve hose, which is about the gusset edge of the bag wall forming, flattened Material hose out, is referred to as outer valve.
Durch
Der in die Ventilöffnung eingesetzte Ventilschlauch ermöglicht eine geführte Befüllung des Ventilsacks mit dem Füllgut durch ein Füllrohr einer Füllmaschine hindurch. Nach dem Befüllen des Ventilsacks drückt das Füllgut den Ventilschlauch flach zusammen, das für viele Anwendungsfälle einen ausreichend dichten Verschluss der Ventilöffnung bewirkt.Of the into the valve opening used valve tube allows a guided filling the valve bag with the contents through a filling tube a filling machine therethrough. After filling of the valve bag presses the contents the valve tube flat together, the one for many applications sufficiently tight closure of the valve opening causes.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Herstellung eines Ventilsacks mit einem einfacher handzuhabenden verschweißbaren Ventil zu er möglichen, bei dem darüber hinaus Beschichtungsmaterial eingespart werden kann.Of the present invention is based on the object, the production a valve sack with a more easy to handle weldable valve to him possible at the above In addition, coating material can be saved.
Zur Lösung dieser Aufgabe ist das Verfahren der eingangs erwähnten Art erfindungsgemäß dadurch gekennzeichnet, dass die verschweißbare Schicht als Dispersion auf das Ventilblatt in Form eines Streifens aufgedruckt wird, dessen Fläche weniger als die Hälfte der Fläche des Ventilblatts einnimmt.to solution this task is the method of the type mentioned according to the invention thereby characterized in that the weldable layer as a dispersion is printed on the valve sheet in the form of a strip whose area less than the half the area of the valve sheet occupies.
Zur Lösung der gestellten Aufgabe ist ferner ein Ventilsack der eingangs erwähnten Art erfindungsgemäß dadurch gekennzeichnet, dass die Beschichtung als ein aufgedruckter Streifen ausgebildet ist, dessen Fläche weniger als die Hälfte der Fläche des Ventilblatts einnimmt.to solution the task is also a valve bag of the type mentioned according to the invention thereby characterized in that the coating as a printed strip is formed, whose area less than the half the area of the Valve sheet occupies.
Gemäß der vorliegenden Erfindung wird die schweißbare Beschichtung in ungewöhnlicher Weise auf das Ventilblatt aufgedruckt. Durch die Verwendung eines Druckverfahrens, insbesondere des Siebdruckverfahrens, lässt sich ein definierter Materialauftrag, vorzugsweise mit einer wässrigen Dispersion, auf einer Teilfläche des Ventilblattes in Streifenform realisieren. Die schweißbare Schicht hat nach der Trocknung vorzugsweise ein Flächengewicht von 50 g/m2.According to the present invention, the weldable coating is unusually printed on the valve sheet. By using a printing process, in particular the screen printing process, can be a defined material order, preferably with an aqueous dispersion, realize on a partial surface of the valve sheet in strip form. The weldable layer preferably has a basis weight of 50 g / m 2 after drying.
Der aufgedruckte Streifen kann sehr schmal ausgebildet sein und beispielsweise weniger als 1/4 oder 1/5 der Fläche des Ventilblatts in Längsrichtung des Ventilschlauchs gesehen einnehmen.Of the Printed strips can be made very narrow and, for example less than 1/4 or 1/5 of the area of the valve sheet in the longitudinal direction of Take the valve tube.
In einer bevorzugten Ausführungsform des erfindungsgemäßen Herstellungsverfahrens wird die schweißbare Schicht als Querstreifen auf ein kontinuierlich vorgefördertes Endlosband aufgedruckt. Nach dem Aufdrucken wird die Lage des aufgedruckten Streifens optisch detektiert und zur Steuerung eines Trennmessers zum Abschneiden des Ventilblatts von der Endlosbahn verwendet. Hierfür kann das verschweißbare Material in einer Farbe verwendet werden, die mit dem Material des Ventilblattes kontrastiert, damit eine optische Erkennbarkeit gegeben ist. In diesem Fall wird das aufgedruckte Material der schweißbaren Beschichtung selbst optisch detektiert. Als „Farbe" wird dabei jede mit dem Material des Ventil blattes kontrastierende Erscheinungsform verstanden. Eine Zugabe einer Farbe ist dann erforderlich, wenn eine üblicherweise durchsichtige Acrylatbeschichtung als Träger verwendet wird. Die optische Detektion kann auch mittels einer aufgedruckten Markierung erfolgen. Die Steuerung des Trennmessers ist jedoch auch in anderer Form möglich, beispielsweise mit einer optisch oder mechanisch detektierbaren Ausstanzung.In a preferred embodiment the production process according to the invention becomes the weldable Layer as a horizontal strip on a continuously pre-conveyed Endless tape printed. After printing, the position of the printed Strip optically detected and to control a cutting knife used to cut off the valve sheet from the continuous web. For this, the weldable Material used in a paint that matches the material of the Valve sheet contrasted, so given a visual recognition is. In this case, the printed material of the weldable coating even optically detected. As "color" is doing each with the material of Valve leaf understood contrasting manifestation. A Adding a color is required if one is customary transparent acrylate coating is used as a carrier. The optical detection can also be done by means of a printed mark. The control However, the separating knife is also possible in other forms, for example with an optically or mechanically detectable punching.
Durch das gesteuerte Abschneiden des Ventilblattes von dem Endlosmaterial ist es erreichbar, dass das Ventilblatt am Ende des aufgedruckten Streifens abgeschnitten wird, sodass der aufgedruckte Streifen als schweißbare Schicht am äußeren Ende des Ventilschlauchs positioniert ist, wo er für den Verschweißvorgang mit entsprechenden Schweißwerkzeugen am besten ergriffen werden kann.By the controlled cutting of the valve sheet from the continuous material It is achievable that the valve sheet at the end of the printed strip is cut so that the printed strip as a weldable layer at the outer end The valve tube is positioned where it is needed for the welding process with appropriate welding tools can best be taken.
Bevorzugt ist die Verwendung der Erfindung bei einem Ventilsack mit einem Stummelventil, wie es am häufigsten für verschweißbare Ventilschläuche verwendet wird.Prefers is the use of the invention in a valve bag with a Stub valve as it most often used for weldable valve hoses becomes.
