The
ability of light leathers such as those used in shoe uppers,
gloves and garments to withstand repeated flexing without
cracking is determine with the help of a flexometer. The test
specimen 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 grips 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 assess the damaged produced.
