Description

Verfahren zur Erhöhung der Lagerungsbeständigkeit gedehnter, unter Wärmeeinwirkung schrumpfbarer Schläuche aus thermoplastischem Kunststoff Die Erfindung betrifft ein Verfahren zur Erhöhung der Lagerungsbeständigkeit gedehnter, unter Wärmeeinwirkung schrumpfbarer Schläuche aus thermoplastischem Kunststoff. Method of increasing the storage stability of stretched, under Heat exposure of shrinkable tubing made of thermoplastic material The invention relates to a method of increasing the shelf life of stretched, under Heat exposure of shrinkable tubing made of thermoplastic material.

Es ist bekannt, Gebrauchsgegenstände aus Holz oder Metall, z. B. Möbel, dadurch mit einer Kunststoffhaut zu überziehen, daß ein thermoplastischer Kunststoffschlauch zunächst gedehnt, sodann über den zu überziehenden Gegenstand gezogen und schließlich auf diesem durch Wärmeeinwirkung geschrumpft wird. It is known to use objects made of wood or metal, e.g. B. Furniture, to be covered with a plastic skin, that a thermoplastic Plastic tube stretched first, then over the object to be covered pulled and finally shrunk on this by the action of heat.

Die Hersteller der Kunststoffschläuche liefern diese an die Verbraucher in gedehntem Zustand, so daß die Verbraucher die Schläuche nur überzuziehen und durch Wärmeeinwirkung schrumpfen zu lassen brauchen. Bei längerer Lagerung schrumpfen die gedehnten Schläuche aber selbsttätig und können daher später nicht mehr über die Gebrauchsgegenstände, z. B. Stahlrohre, gezogen werden, weil ihre lichte Weite zu gering geworden ist. The manufacturers of the plastic hoses supply these to the consumers in a stretched state, so that the consumer just pulls on the hoses and need to shrink through the action of heat. Shrink if stored for a long time but the stretched hoses automatically and can therefore no longer over later the utensils, z. B. steel pipes, because their clear width has become too low.

Dieser Nachteil wird bei dem Verfahren der Erfindung nun dadurch beseitigt, daß die beidendig geschlossenen Schläuche mit Gas, insbesondere Luft, unter einem Überdruck von etwa 1 atü gefüllt werden. This disadvantage is now eliminated in the method of the invention eliminates that the hoses closed at both ends with gas, especially air, be filled under an overpressure of about 1 atm.

Sie können dann unbegrenzt lange gelagert werden, ohne ungewollt zu schrumpfen. Durch einfaches Abschneiden der Enden werden die Schläuche gebrauchsfertig gemacht.They can then be stored for an unlimited period of time without accidentally becoming shrink. Simply cut off the ends to make the tubing ready for use made.
