KAISERLICHES A IMPERIAL A
PATENTAMTPATENT OFFICE
Bisher hatte man zur Aufnahme von Zement gewebte Stoffsäcke verwendet. Da diese, trotzdem sie aus billigem Material hergestellt sind, doch verhältnismäßig noch teuer sind, so hat man versucht, derartige Säcke aus Papier herzustellen. Es ergab sich aber, daß derartige Papiersäcke, wenn sie einen stumpfen Anstoß erhielten oder fielen, wenn z. B. ein Arbeiter den mit Zement gefüllten Papiersack nach derWoven cloth sacks had previously been used to hold cement. Because this, anyway they are made of cheap material, but are still relatively expensive, so has attempts are being made to make such sacks from paper. But it turned out that such Paper bags if they received a blunt bump or fell, e.g. B. a worker the paper sack filled with cement after the
ίο bei Stoffsäcken üblichen Weise von der Schulter auf die Erde fallen ließ, platzten. Versuche ergaben, daß dies darauf zurückzuführen ist, daß die Luft an einer Stelle im Sack beim stumpfen Anstoß oder Fall plötzlich verdrängt wird und nicht entweichen kann, wie dies bei Stoffsäcken möglich ist, so daß der Papiersack gesprengt wird. Um diesem Übelstande abzuhelfen, ist nach vorliegender Erfindung der Papiersack aus gefilzten, d. h. zusammenhängenden Papierbahnen hergestellt, die luftdurchlässig gemacht sind. Hierdurch wird das Platzen der Säcke vermieden und der Papiersack aus gefilzten Papierbahnen als billigeres Ersatzmittel für Stoffsäcke praktisch verwendbar gemacht.ίο the usual way off the shoulder with cloth sacks dropped to the ground, burst. Tests have shown that this is due to that the air at one point in the sack is suddenly displaced when it is struck or dropped and cannot escape, as is possible with cloth sacks, so that the paper sack is blown up. In order to remedy this inconvenience, is according to the present invention the felted paper sack, d. H. continuous paper webs made that are air-permeable are made. This prevents the bags from bursting and the paper bag made of felted paper webs is cheaper Substitutes for cloth sacks made practically usable.
Als Ersatz für Stoffgewebe ist auch schon ein Papiergewebe vorgeschlagen, das nur aus Papier oder aus Papier und Textilfaden hergestellt werden soll. Zur Herstellung solcher gewebter Papierbahnen sind aber ganz besondere Maschinen nötig, was zur Folge hat, daß das Endprodukt zu teuer ist. Aus diesem Grunde läßt sich dieses Papiergewebe nicht zur Herstellung von billigeren Ersatzmitteln für die gebräuchlicheren Jutezementsäcke verwenden. As a substitute for fabric, a paper fabric has also been proposed that only consists of Paper or to be made from paper and textile thread. To produce such Woven paper webs, however, require very special machines, which means that the end product is too expensive. For this reason, this paper fabric cannot use to make cheaper substitutes for the more common jute cement bags.
Der Papiersack kann auf verschiedene Art und Weise luftdurchlässig gemacht worden sein. So kann die gefilzte Papierbahn viele von außen nach innen gestochene, feine Nadellöcher~besitze7fT~ welche dann, da sie trichterförmig nach innen gehen und innen von dem durch die Nadel verdrängten Grat umgeben sind, kaum Material, z. B. Zement, aus dem Sack treten lassen, wohl aber Luft. Die Löcher können auf verschiedene Art und Weise hergestellt sein, z. B. durch Stanzen, Walzen, entweder an den Papierbahnen vor der Herstellung des Sackes oder am fertigen Sack nach dessen Herstellung.The paper sack can be made air-permeable in various ways be. The felted paper web can have many fine pinholes that are pierced from the outside to the inside which then, as they funnel-shaped go inwards and inside of that are surrounded by the burr displaced by the needle, hardly any material, e.g. B. cement, from the Let the sack kick, but air. The holes can be made in different ways be e.g. B. by punching, rolling, either on the paper webs before manufacture of the sack or on the finished sack after its manufacture.
