Description

Vorrichtung zur Entlüftung der bei der Herstellung von Wellpappe entstehenden Riffelröhren Nach dem Patent 499 135 wird zwecks Erreichung besserer und schnellerer Trocknung des Klebstoffes bei der Herstellung von Wellpappe durch die dabei entstehenden Riffelröhren Luft gesaugt, wobei die nachströmende Luft, um bei einseitigen Maschinen eine Kühlung der Walze und dementsprechend bei doppelseitigen Maschinen eine Abkühlung der Heizplatten zu verhindern, äuf ungefähre Wandungstemperatur vorgewärmt wird. Bei diesem Vorgang wird die in den Riffelröhren befindliche, mit Wasserdampf angereicherte Luft durch weniger gesättigte Luft ersetzt.Device for venting the resulting in the manufacture of corrugated cardboard Corrugated tubes According to the patent 499 135, in order to achieve better and faster Drying of the adhesive in the manufacture of corrugated cardboard due to the resulting Corrugated tubes sucked in air, with the inflowing air in order to unilateral machines a cooling of the roller and accordingly a cooling in double-sided machines To prevent the heating plates from being preheated to the approximate wall temperature. During this process, the water vapor contained in the corrugated tubes is enriched Air replaced with less saturated air.

Erfindungsgemäß wird in der Warmluftzuleitung für die Riffelröhren, also vor der Warmlufteintrittsstelle in letztere, eine Drosselklappe o. dgl. angeordnet, so daß in den Rifl"elröhren die Luftdichte bzw. der Unterdruck geregelt werden kann. Dadurch drückt die atmosphärische Luft auf die Deckbahn der Wellpappe und bewirkt ein sicheres Aufliegen der Deckbahn auf den Wellenbergen der Riffelbahn bei der Trocknung des Klebstoffes. Bei den bekannten Maschinen wird dieses Aufliegen durch Lattenbänder, massive Walzen, Filztücher usw. erreicht. Diese Maßnahmen haben den Nachteil, daß die Wellpappe entweder verdeckt (z. B. Filztuch) und dadurch der Beobachtung des Maschinenführers entzogen wird oder daß das Gewicht der Andruckvorrichtungen die `'Felle der Wellpappe quetscht.According to the invention, in the hot air supply line for the corrugated tubes, so in front of the hot air inlet point in the latter, a throttle valve or the like. so that the air density or the negative pressure can be regulated in the Rifle tubes. As a result, the atmospheric air presses on the cover sheet of the corrugated cardboard and causes a secure resting of the cover sheet on the wave crests of the corrugated sheet at the Drying of the glue. In the known machines, this resting is caused by Slatted belts, massive rollers, felt cloths, etc. achieved. These measures have the Disadvantage is that the corrugated cardboard is either covered (e.g. felt cloth) and thus visible of the machine operator is withdrawn or that the weight of the pressure devices squeezes the skins of the corrugated cardboard.

Vorliegende Erfindung vermeidet diese Nachteile. Der Druck der Atmosphäre auf die Deckbahn wirkt vollständig gleichmäßig. Eine direkteGewichtsbelastung der Wellpappe ist nicht vorhanden.The present invention avoids these disadvantages. The pressure of the atmosphere acts completely evenly on the cover sheet. A direct weight load on the Corrugated cardboard is not available.
