Shoes Vamp Flexing Tester
Application
This machine is used to test vamp flex test-resistance to creasing and cracking
Product information
To primarily intended to determine the propensity for materials to crack or be used to assess whether leathers are likely to produce salt spue. In particular the test simulates conditions in the vamp part of footwear during walking. The test can be conducted with either wet or dry specimens at room temperature or with dry specimens at sub zero temperatures. The method is applicable to all flexible materials and in particular those used to manufacture outers and linings of footwear uppers such as leathers, coated fabrics and textiles
Principle
The sample is fixed on the fixture, and the clamp moves relative to each other, so that when the two clamps are close, the specimen is bent. During the test, the clamp moves at a constant speed, and the specimen is repeatedly bent. Observe the damage of the specimen.
