Description
Es sind mannigfaltige Apparate bekannt, welche geeignet sind, den Berstwiderstand von Papier od. dgl. zu prüfen und zu messen. Bei den bekannten Apparaten wird meist die Messung jeweils an einer einzigen Prüf fläche vorgenommen, so daß, um einen repräsentablen Mittelwert zu erhalten, meist zehn Messungen gebräuchlich sind.Various devices are known which are suitable for reducing the bursting resistance of paper or the like. to test and measure. In the case of the known devices, the measurement is usually carried out on a single one Test area made so that in order to obtain a representable mean value, usually ten Measurements are in use.
Diese Messungen erfordern einen verhältnismäßig großen Aufwand an Zeit.These measurements require a relatively large amount of time.
In der Praxis ist es aber oft erforderlich, schnell eine Vergleichsmessung zwischen z. B. zwei verschiedenen Packpapieren, Papiersäcken od. dgl. anzustellen. Für diesen Zweck eignet sich in besonderer Weise die Vorrichtung gemäß der Erfindung.In practice, however, it is often necessary to quickly make a comparison measurement between z. B. two different Wrapping papers, paper sacks or the like. For this purpose is particularly suitable the device according to the invention.
Gegenüber den bekannten Prüfvorrichtungen liegt ihr das Ziel zugrunde, zur Messung eine größere Anzahl von Prüfflächen in einem einzigen Meßvorgang heranzuziehen. Dies wird durch die Anordnung einer Anzahl von Nadeln an einem Prüfknopf erreicht, wobei die Nadeln in der Länge gleichmäßig abgestuft sind. Beim Durchstoßen der Probe wird erst eine Nadel auftreffen. Die nächste Nadel trifft erst auf der Probe auf, wenn die erste bereits eingedrungen ist, die dritte, wenn die erste die Probe schon durchstoßen hat usw.Compared to the known test devices, it is based on the goal of measuring a larger number to be used from test surfaces in a single measurement process. This is done by arranging a Number of needles reached on a test button, the needles evenly graduated in length are. When the sample is pierced, a needle will hit it first. The next needle only hits the sample when the first has already penetrated, the third when the first has already penetrated the sample has etc.
Die Zeichnung gibt die Erfindung in einer schematischen Anordnung wieder, wobei der Prüfknopf als Fallgewicht ausgebildet ist.The drawing shows the invention in a schematic arrangement, the test button as Falling weight is formed.
In einem Ständer mit Führung a gleitet das Fallgewicht b. An der Unterseite des Fallgewichtes sind die Nadeln angeordnet. Mit der Festhaltevorrichtung c wird das Gewicht in seiner oberen Lage festgehalten. Auf den Prüftisch d, welcher Durchlässe für die Nadeln besitzt, wird das Prüfstück e gelegt. Wird nun die Festhaltung c gelöst, so fällt das Gewicht nach unten, und die Nadeln — die längste zuerst — durchstoßen den Prüfling. Nach einer vom Prüfmaterial abhängigen Anzahl von Durchstoßungen ist die Fallenergie des Gewichtes aufgebraucht. Die Eindringtiefe des Prüfkopfes wird mittels einer Lupe / auf der Skala g abgelesen.The falling weight b slides in a stand with guide a. The needles are arranged on the underside of the drop weight. With the retaining device c , the weight is held in its upper position. The test piece e is placed on the test table d, which has openings for the needles. If the retention c is now released, the weight falls down and the needles - the longest first - pierce the test specimen. After a number of punctures, depending on the test material, the weight's energy is used up. The penetration depth of the test head is read off using a magnifying glass / on the scale g.
Um verschiedene Meßbereiche erfassen zu können, ist das Fallgewicht mittels weiterer Haltevorrichtungen c' von verschiedenen Höhen herabzulassen. Es können aber auch wahlweise mehr oder weniger Ge-Vorrichtung zum Prüfen des Berstwiderstandes von Papier od. dgl. In order to be able to cover different measuring ranges, the falling weight is to be lowered from different heights by means of further holding devices c '. But it can also optionally more or less Ge device for testing the bursting resistance of paper od. Like.
