Bally Leathers Flexing Tester DW9420

Bally leathers flexing tester is mainly used to determine the flexing resistance of various leather and cloth materials subjected to reciprocating flexing. The inside and outside of the materials to be tested are clamped, and the damaged condition of the tested materials will be observed after reciprocating flexing for pre-determined times. It is applicable to all types of thin leathers for production of shoe uppers, clothes, bags, etc.

A test piece is folded with the surface to be tested inwards and clamped in the upper movable clamp and with the surface to be tested outwards in the lower fixed clamp. Flex the test piece with speed of 100 cycles per minute and flex angle of 22.5° till the piece cracks, then record the flexing times. Or flex the test piece according to the above method for pre-determined flexing times and observe whether cracking occurs. The damage to the test piece can be examined by a magnifier.
