Tests on specimens of Leather and Footwear that you cannot afford to ignore.

Unravel an irresistible range of leather testing equipment such as flexometer, lastometer-bench & handy type, sole adhesion tester, tensile testing machine etc. Useful for ball burst test and sole adhesion strength test, range of our equipments is manufactured from top grade metal and are furnished with zinc plating for corrosion resistant finish. Leather testing equipment are available with few optional accessories such as cutting die, cutting press etc.

The ability of light leathers and leather-cloth used in manufacture of shoe uppers, gloves, and garments to withstand repeated flexing without cracking is determined with the help of a flexing endurance test.

In this test, test specimens in 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 centre. This operation is carried out repeatedly and the test specimens inspected periodically to assess the damage produced. The equipment used for this test is called as Flexometer.

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

Motion to the oscillating grips is given through a link mechanism, which oscillates the shaft on which the grips are mounted. All the pivot points of the mechanism have ball bearings to ensure smooth operation and a long working life.
The link mechanism is give motion from an electric motor and two sets of V-pulleys. A six-digit electronic counter with key-reset and backup memory is provided to record the total number of flexing cycles undergone by the test specimens.

The apparatus is finished in bright chrome/zinc plating and grey hammer tone stove painting to give it a corrosion resistant finish.

The standard model of flexometer can test upto six specimens at one time. Special models capable of testing either twelve or twenty-four test specimens at one time can also be offered against specific requirements.

Specimen cutting die and cutting press are also available as optional accessories.

The determination of distension and strength of grains of any leather sample are conveniently be carried out with the help of the ball burst test. In this test, a hemispherical hardened metallic tip is pressed against one face of the leather disc held in a suitable non-slipping grip and the force needed to make the tip pierce through the test specimen determined to evaluated the grain strength. The distention of leather at which the tip pierces through is also determined.

The strength of adhesion of a sole to its upper is determined by measuring the force needed to pull off the sole from the upper. A suitable last is placed inside the shoe, which is then placed on a straight edge acting as a fulcrum for applying load on the joint of the sole and upper. The maximum load the sole can withstand before coming off is determined and reported as the sole adhesion strength. This test can be carried out either at the heel or at the toe of the shoe.

The PROLIFIC Sole Adhesion Tester consists of a cantilever type load cell with a digital readout to measure and indicate the force applied at the junction of the sole or heel and the upper and a set of interchangeable toe pieces having different curvatures.

The load cell measures the force applied on the joint, which is indicated directly in kilograms on a digital readout with a peak force memory to indicate the maximum force applied before the failure of adhesion.

Five toe pieces of different curvatures are provided to enable toes and heels of different shapes and sizes to be tested. The length of arc of each toe piece, however, is the same to ensure that the force is applied only on a fixed length of joint. These are made from carbon steel for giving a long operational life. Any one of the toe pieces can be held in the equipment at one time.

The fulcrum on which the shoe is placed during the test has adjustable height to enable soles of different thickness to be tested. The height of the fulcrum is adjusted with the help of six spacer strips provided with the equipment.

The equipment is finished in grey hammertone stoving painting and bright chrome / zinc plating to give it a corrosion resistant finish.
