Description and Specification for Lab Tenders
Belt Flex Tester.
Out soles of footwear or other flexing components may suffer cracking in
use due to flexing. Cracks usually develop at points of high surface
strain resulting from the design of the sole pattern, without there
being any cuts to initiates them. The Belt Flex Tester is designed to
flex complete soles with their patterns intact in a manner similar to
those encountered in actual use. Tests carried out using it provide a
guide to the risk of such cracks developing during use.
