Rycolab Twin Folding Tester
For measuring the folding resistance of paper or board according to the Schopper principle
Applicable standards
ISO 5626, TAPPI T523, NF Q03-062, NFISO 5626
Device description
Measures the number of folds that it takes until the sample breaks. The test requires two samples to be tested simultaneously. Units are available for paper or for board samples.
The instrument is equipped with a touch screen displaying the temperature, the number of folds and statistical values. The heads are equipped with temperature sensors to convey the temperature inside the heads.
Test description
Two samples are clamped in the folding heads for a simultaneous test. The spring loaded sample supports are pulled apart, so that the samples are clamped at the specified force. After pushing the start button, the folding knives begin to guide the sample around the sapphire supported folding rolls. That way the samples are folded on both sides at a radius of 0.25 mm.
If one sample breaks, the folding process of the second sample continues until it also breaks. The movement of the folding heads stop after test termination, so that the samples can be removed. The device records the number of folds it takes until the sample breaks and then displays them on the touch screen.
