Double / Twin Folding Endurance Tester
Determines the folding resistance of paper according to the Louis Schopper method.
Full Description
Double folding strength test
Code: E.103.x
Use
For determining the folding resistance of paper (or cardboard) in accordance with the Louis-Schopper method.
Device description
The device measures the number of folds until the sample tears. Two samples are tested simultaneously. The integrated touchscreen display shows the temperature, the number of folds and statistical values. The folding heads are fitted with temperature sensors to monitor the internal temperature of the heads.
Features
- easy and user-friendly operation via touchscreen
- Standard version for paper up to 0.25 mm thick; optional version for cardboard up to 1.50 mm thick
- statistical funktions
- display of the temperature of each folding head and the ambient temperature
- RS 232 interface
- specifically for security paper testing
- automatic stop after sample break
- CE certified
