Specifications:

The Bata belt flexing machine is designed to determine the crack initiation and growth due to repeated flexing of the outsole. machine should provide one of the best indications of the risk of cracking shoe soles due to flexing in wear. The larger main drive pulley provides the rotation while the smaller of the two pulleys determines the severity of the flexing action. Equipment should be supplied complete with three small pulleys of varying diameters to increase or decrease the amount of flexing. endless belt that accommodates six sole units, subject to the style and size. Sole units bonded to the belt using a strong adhesive. belt made of canvas and construction allows the number of complete cycles to be counted which is equal to the number of flexes of the test sample. The flexing area is provided with a full guard interlocked with the machine controls to ensure the guard cannot be opened until the belt has stopped.

The machine should be suitable for the testing of all shoe sole units and should be used with other flexible materials.
