SATRA STM 184 Whole shoe flexing machine

The STM 184 flexing machine has been developed to assess the flexing endurance of completed footwear in wet and dry conditions.

The machine is supplied in both single or twin station formats and the action simulates the flexing of footwear during wear. The angle of flex is adjustable up to 50°. The machine may be used to predict the failure of footwear in wear. It is particularly useful in assessing problems associated with bottom construction.

Footwear is clamped to the machine at the toe end using the appropriate toe clamp from one of five pairs supplied. The heel end is secured to the flexing bar. A predetermining counter is fitted and once the appropriate number of flexes has been registered, it will stop the machine so that the shoe can be inspected.

The moving parts of the machine are covered by a hinged guard which is fitted with the latest safety device to prevent access while the machine is still in use. The machine is robust and non-corrosive materials are used where applicable in its construction.

A similar machine is available for testing high leg boots (STM 184H) where water depth can be increased to cover the whole forepart of the footwear up to eyelet level. Details available on request.
