FLEXOMETER

 

.               The ability of light leathers such as those used in shoe uppers, gloves and garments to with stand repeated flexing without cracking is determined with the help of a flexometer. In this test, the test specimens in the shape of rectangular pieces are folded and clamped at each end to maintain them in a folded position in a set of grips, one of which is fixed while the other is able to oscillate. The movement of the oscillating grip causes the fold in the test specimen to run along its fold. This operation is carried out repeatedly and the test specimens inspected periodically to Asses the damaged produced.

The ASIAN Flexometer is built on a rigid metallic base plate. The test specimen is held between a pair of stationary and oscillating grips. The grips are specially designed to enable quick fixing and removal of test specimen and are shaped to meet the specification.

The motion of the oscillating grips is given through a link mechanism, which oscillates the shaft carrying the grips. All the pivot points of the apparatus have ball bearing to ensure the long life and smooth operation.

The driving force to the link mechanism is given through a ¼ hp single-phase motor and two sets of V-pulleys. A six digit even electronic counter with key reset and backup memory is provided to count the total number of flexing cycles undergone by the test specimens.

The apparatus is finished in bright chrome/ zinc plating and NC based painting to give it a corrosion resistance finish

Specimens cutting die and cutting press are also available as operational accessories.
