Abstract

Sheet material consisting of metal foil coated with thermoplastic material on both sides is wrapped round a shaper, and soft plastic extruded into the zone where the edges overlap. The edges are pressed and rolled by a heated roller to give a smooth seam. The resulting tubing is impermeable preventing either oils or aromatics passing through the walls.

Gleichzeitig zeigt die Erfindung eine das Verfahren durchführende Vorrichtung.Method and device for the production of tubular blanks for the production of tubes from coating material The invention relates to a method for the production of tubular blanks for the production of tubes from layered material, such as made of metal and / or plastic, paper or the like., The outer sides of the material formed by at least one thermoplastic plastic layer and the material is deformed into a hollow cylinder with the formation of a longitudinal seam will. At the same time, the invention shows a device performing the method.

Zusammendrückbare Behälter, wie Tuben od.dgl., wobei zumindest eine Bahn des Schichtmaterials eine Metallschicht ist, sind seit längerem bekannt. Die Metallschicht soll dabei verhindern, dass sich im Tubeninhalt befindliche ätherische Öle, Aromastoffe nach aussen hin verflüchtigen bzw. dass von aussen her in das Behälterinnere irgendwelche Stoffe eindringen, die den Behälterinhalt, beispielsweise Lebens-oder Genussmittel, verderben lassen. Diesen Nachteil haben beispielsweise Kunststofftuben aus Polyäthylen. Ein Nachteil von Tuben aus Schichtmaterial besteht darin, dass das Schichtmaterial an dem innenliegenden Längsrand freiliegt, so dass Teile des Behälterinhaltes zwischen die das Schichtmaterial bildenden- Schichten eindringen und dieses zerstören können. Diesen Mangel zu beseitigen, erschwert die Herstellung von Tuben aus Schichtmaterial. Man hat deshalb bereits vorgeschlagen (US-Patentschrift 2 440 339), das Schichtmaterial vor der Nachbildung U-fö.rmig umzuschlagen, so dass im Tubeninnern keine Längsseiten des Schlauchmaterials mehr freiliegen.Compressible containers, such as tubes or the like., At least one Because the layer material is a metal layer, have long been known. the The metal layer is supposed to prevent the essential substances in the tube Oils, flavorings evaporate to the outside or that from the outside any substances penetrate into the interior of the container which could For example, food or luxury foods can spoil. Have this disadvantage for example plastic tubes made of polyethylene. A disadvantage of tubes made of laminated material consists in that the layer material is exposed on the inner longitudinal edge, so that parts of the container contents between the layers forming the layer material can penetrate and destroy it. Eliminating this deficiency makes it difficult Manufacture of tubes from laminated material. It has therefore already been proposed (US Pat. No. 2,440,339), the layer material before the replication is U-shaped to be turned over so that there are no longer any longer sides of the hose material inside the tube exposed.

Ein anderer bekannter Vorschlag (OS 1 486 125) geht dahin, die aussenliegenden Kunststoffschichten an den Rändern über die Mittelschicht hinaus zu verlängern und miteinander zu verbinden, so dass das Schichtmaterial dadurch einen Kantenschutz hat. Weitere Verfahren zur Bildung eines Kantenschutzes bei Schichtmaterial sind in der OS 1 486 190 bzw. 1 486 193 bekanntgeworden.Another well-known suggestion (OS 1 486 125) is the outward one Plastic layers on the edges extend beyond the middle layer and to connect with each other, so that the layer material thereby an edge protection Has. Other methods of forming edge protection for layered material are became known in OS 1 486 190 and 1 486 193.

Wie ersichtlich, haben die bekannten Verfahren alle den Nachteil, dass sie zu ihrer Durchführung einen mechanischen Aufwand bzw. komplizierte Fertigungsvorrichtungen erfordern. Diese Mängel werden erfindungsgemäss dadurch vermieden, dass zur Längsnahtbildung sofort zusätzlich thermoplastisches Kunststoffmaterial zwischen die sich überlappenden Materialränder eingebracht und durch Druck- und Wärmeeinwirkung zum Abbinden mit den anliegenden Kunststovfbehichten des Schlauchmaterials gebracht wird. Das zusätzliche Kunststoffmaterial lässt sich im plastifizierten Zustand zwischen die Überlappungsränder einbringen oder im kalten Zustand und anschliessend durch Wärmeeinwirkung plastifizieren.As can be seen, the known methods all have the disadvantage that they require a mechanical effort or complicated manufacturing devices for their implementation require. According to the invention, these deficiencies are avoided by forming a longitudinal seam Immediately add thermoplastic plastic material between the overlapping ones Material edges introduced and with the effect of pressure and heat to set is brought to the adjacent Kunststovfbehichten the hose material. The additional Plastic material can be placed between the overlapping edges in the plasticized state bring in or plasticize in the cold state and then by the action of heat.

Mit besonderem Vorteil kann das Kunststoffmaterial in Form eines Profilstranges eingebracht werden, der zweckmässig verstärkte Längsränder hat, die nach dem Einbringen die Längsränder des Schichtmaterials abdecken.The plastic material can be particularly advantageously in the form of a profile strand be introduced, which has expediently reinforced longitudinal edges, which after the introduction cover the longitudinal edges of the layer material.
