Belt Flex Tester For Testing Lab

Belt Flex Tester - For Testing Lab Out-soles of footwear or other flexing components may suffer cracking due to flexing in use. Cracks usually develop at points of high surface strain resulting from the design of the sole pattern, without there being any cuts due to grit etc. to initiate them.   The Belt Flex Tester is designed to flex complete soles with their patterns intact in a way similar to flexing in actual use. Tests carried out using it provide a guide to the risk of such cracks developing during use.   In this test, test specimens are attached to the outside of a continuous belt, which is driven round two rollers. The larger roller drives the belt, while movement of the belt round the smaller roller provides the main flexing action. The radius of the smaller roller is chosen to make the flexing either more severe or less severe than in actual use civil lab equipments manufacturers
