SATRA STM 701 Bally flexometer

The SATRA Bally flexometer is the internationally-accepted method for the assessment of the flexing endurance of light leathers and their surface finishes. The tendency for cracks to form in the creases caused by walking can also be determined.

The Bally flexer has a different flexing mechanism to the SATRA vamp flexer (STM 601) and is complementary to it. It is also used to precondition samples prior to determining water vapour permeability – particularly in assessing uppers for protective footwear.

The twelve stations are conveniently arranged for user access and sample mounting. A predetermined counter is fitted to the machine, allowing it to be operated without continuous attendance as the machine stops automatically once the set count is reached.

The machine is simple to use, bench mounted and supplied ready to connect to the electrical supply.

There is a four station version of this machine (SATRA Ref. STM 702). Low temperature versions are also available (to -20°C) subject to ambient temperatures in location of machine.
