Application
The Bally Flexing Tester (Flexometer) is designed to evaluate the flexing resistance of materials by testing their durability under bending or other types of failure at flexing creases. It is primarily used to assess the bending resistance of flexible materials such as leather, artificial leather (below 1.0 mm in thickness), and other coated fabrics or sheet materials.
What is a Flexometer?
A flexometer, also known as a Bally Leather Flexing Tester or Leather Bending Tester, is an international instrument used to assess the bending resistance of various light leathers and their surface modifiers. It is mainly used to test the durability of leather and similar materials under continuous bending stress.

Testing Method
How to Use a Flexometer for Testing?
In a flexometer test, the specimen is placed into the machine’s fixture, with one side of the sample serving as the internal side and the other as the outer side. The sample undergoes reciprocating bending to simulate continuous flexing. The tester then observes the sample for signs of damage or failure. The number of bending cycles is counted (from 1 to 999,999), and the degree of damage is recorded, often with the aid of a magnifier. This process helps evaluate the flexural strength and durability of the material being tested.
