Flexometer / Bally Leather Flexing Tester
Bally flex tester is designed to evaluate the flexural resistance of leather to continual flexure. The 12-station flex tester is a popular model. The user can easily change the station arrangement, take and install samples. The whole tester is of stainless steel structure. Digital counter can preset the running times so that the instrument automatically stops when reaching the set values with no need of staff to attend to.
Bally flex tester is designed to evaluate the flexural resistance of leather to continual flexure. It is an universal instrument to assess the flexural resistance of all kinds of light leathers and surface trim, as well as to evaluate the specimen’s propensity to crack, similar to the crease that forms in a shoe's upper that flexes during walking. The flexing mechanism of the Bally flex tester is different from that of the shoe upper flex tester. The functions of two testers complement mutually. The tester is also used for the pretreatment of specimens prior to the determination of water vapor permeability– especially of shoe upper materials used for protective footwear.
