Introduction
This instrument evaluates the fatigue resistance of leather edges and coated surfaces. Samples are subjected to reciprocating bending under specified load, speed, and cycle conditions. The tester observes:
Surface cracking
Coating detachment
Delamination
It is ideal for assessing the durability of:
Waistbands
Backpack straps
Luggage handles
Other belt-type leather products
