  • Product description

    The device measure the number of folds until the sample breaks. The test requires that two samples be tested simultaneously.
    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 0.25mm. If one sample breaks, the folding process of the second sample continues until it breaks too. The movement of the folding heads stop after test termination, so that the
    samples can be removed. The device records and displays the number of folds until the sample breaks.
