<p style="text-align: justify;"><span style="font-family: tahoma,arial,helvetica,sans-serif; font-size: small; color: #000000;">This equipment is designed to test the water resistance of upper leathers (and upper leather substitutes) under conditions of flexing similar to those in the forepart of a shoe during walking.</span></p>

<p style="text-align: justify;"><span style="font-family: tahoma,arial,helvetica,sans-serif; font-size: small; color: #000000;">One clamp is moved/rotated repeatedly through an angle of 32° by a driven crank linkage. This action forms creases in the specimen similar to those produced during walking. A pre-determined totalising counter is fitted.</span></p>

<p style="text-align: justify;"><span style="font-family: tahoma,arial,helvetica,sans-serif; font-size: small; color: #000000;">Rectangular test pieces are folded down the centre into a vee shape and are held in watertight vee clamps. A tank containing water is then raised by a lever mechanism so that the trough formed by the test piece is surrounded by water. One clamp is then moved up and down repeatedly by a driven crank linkage, forming creases in the leather similar to those produced in the shoe vamp. A resettable totalising counter is fitted and the number of flexes before water penetration is observed and recorded as the test result.</span></p>

<p style="text-align: justify;"><span style="font-family: tahoma,arial,helvetica,sans-serif; font-size: small; color: #000000;">The system incorporates four individual counters, one for each station, plus a visual and an audible alarm. There is a three-position switch to select one of three sensitivities (10K, 30K and 50K ohms). The higher the value, the greater the sensitivity. The individual station counter stops recording when water penetration is first detected and switches on the visual and audible alarm while the remaining stations continue the test. The device can be retro-fitted to existing equipment. The machine accommodates four test pieces.</span></p>
