Bennewart Flex Tester
Model No. FTE004
Bennewart flex testing is intended to determine the resistance of a component of material to cut growth during repeated flexing. It can also be used to assess the effect of surface patterns on crack initiation and growth.
This test is especially applicable to the outsoles of footwear, but may also be used with certain other flexible components.
The Bennewart Flex Tester consists of a drive unit comprising of an electric motor with pulleys and belts and link mechanism to give an oscillating movement to one of the two grips holding the two ends of test specimen, the other grip being fixed.
The oscillating grip has gun metal bushes, which slides on two hardened and ground bearing steel rods to give it a long working life. Each grip consists of swayable bases pivoted on ball bearings so that the two ends of the test specimen are free to align themselves with the natural contour of the specimen during flexing.
The axis about which the grip bases oscillate life. In the plane of their specimen holding face. A six digit pre-set electronic digital counter the numbers of test cycles and also stops the motor after pre-set numbers of test cycles.
The apparatus is finished in gray hammer tone staving, painting and bright chrome/ zinc plating to give it a corrosion resistant finish.
A cutting die for preparation of test specimen from sheet and slitting punch with jig for making initial crack are available as optional accessories.
