Prüfgerät zur Bestimmung der Falzfestigkeit von Papier, dadurch gekennzeichnet, daß das Falzgerät aus zwei beweglichen Klemmbacken zur Aufnahme der Probe besteht, welche sich horizontal gegenüberstehen und daß ein geschlitztes Falzmesser in einer Längskugelführung zwischen vier Falzrollen hin und her gleitet und dabei am Papier eine bestimmte Anzahl von Doppelfalzungen je Minute ausführt, wobei die Klemmvorrichtun­ gen von unten her durch Rollen gestützt werden und frei zwischen Zugfedern schweben, während sie in Bewegung sind und das Falzmesser mit einem vertikalen Schlitz versehen ist, welcher sich jeweils etwas oberhalb beziehungsweise unterhalb der Normallage der Probe verbreitert, wobei die vertikalen Kanten des Schlitzes mit einem Radius versehen sind, welcher der halben Dicke des Falzmessers entspricht, die vier Falzrollen sind sym­ metrisch um den Mittelpunkt des Falzschlitzes angeordnet.1. Tester for determining the fold strength of paper, characterized in that the folder consists of two movable jaws for receiving the sample, which face each other horizontally and that a slotted folding knife slides back and forth in a longitudinal ball guide between four folding rollers and thereby on the paper executes a certain number of double folds per minute, the clamping devices being supported by rollers from below and floating freely between tension springs while they are in motion and the folding knife is provided with a vertical slot, which is slightly above or below the normal position of the Sample widened, the vertical edges of the slot being provided with a radius which corresponds to half the thickness of the folding knife, the four folding rollers are arranged symmetrically around the center of the folding slot. 2. Prüfgerät nach Anspruch 1, dadurch gekennzeichnet, daß in die Vorrichtung ein Zähl­ werk zur Erfassung der Anzahl der durchgeführten Doppelfalze, zur Bestimmung vorge­ gebener Falzungen und zum Anhalten des Gerätes beim Bruch der Probe integriert ist.2. Testing device according to claim 1, characterized in that a count in the device Plant for recording the number of double folds carried out, for pre-determination given folds and to stop the device when the sample breaks. 3. Prüfgerät nach Anspruch 2, dadurch gekennzeichnet, daß dieses Zählwerk so gestaltet ist, daß auch eine bestimmte Anzahl von durchzuführenden Doppelfalzungen vorgege­ ben werden kann.3. Testing device according to claim 2, characterized in that this counter designed so is that also a certain number of double folds to be carried out can be used. 4. Prüfgerät nach Anspruch 1, dadurch gekennzeichnet, daß im Prüfkopf direkt an der Pro­ be ein Temperaturmeßsystem angeordnet ist.4. Test device according to claim 1, characterized in that in the test head directly on the pro be a temperature measuring system is arranged. 5. Prüfgerät nach Anspruch 1, dadurch gekennzeichnet, daß im Prüfgerät ein weiteres Temperaturmeßsystem zum Messen der Umgebungstemperatur angeordnet ist.5. Testing device according to claim 1, characterized in that another in the testing device Temperature measuring system for measuring the ambient temperature is arranged.
