The Leather Cracking Tester (Leather Anti-breaking device) is designed for both industrial and laboratory applications to measure the anti-cracking index in thin leather and upper leather materials.
The specimen's periphery is first fixed by the device, then a ball rises from the leather's inside at a speed of approximately 12mm per minute. When the leather cracks, the value of the rising height is recorded as the measured crack value.
