Testing Equipment

Our Complete range of products are footwear testing equipment, Lea Strength Tester, leather testing equipment, Sole Adhesion Tester and yarn evenness tester.

Footwear Testing Equipment

It consists of test specimen holder with a cylindrical opening adjustable between 15.5 to 16.3 mm to clamp the test specimen with an arrangement to adjust the length of test specimen protruding out. The holder is mounted by a screw mechanism along a length of a rotating drum on which the abrasive cloth is fixed. The movement to the screw mechanism and drum is given by an electric motor, gearbox and chain mechanism to give the specified speed of rotation to the drum and the specified lateral movement to the test specimen holder. The swivel arm and test specimen holder are so disposed that the test specimen is pressed against the drum under the specified load with its center axis at an inclination of 3 degree to the perpendicular in the direction of rotation and placed above the longitudinal axis of drum. A rack and pinion arrangement to rotate the test specimen about its axis during the test (whenever desired) is also provided. The abrasive cloth is firmly fixed to the drum using a suitable peel able adhesive with the ends of the abrasive cloth butt jointed together.

Lea Strength Tester

The lea strength of yarn is one of the major properties on which the suitability of yarn for its ultimate end use depends. The test for determination of lea strength consists of making a lea from the yarn with the help of a warp reel and testing it on the lea strength tester, which registers the maximum load at which the lea starts unraveling. The GLOBE Lea Strength Tester is constructed on a study fabricated steel structure with a heavy base plate which can be directly placed on the ground. The lea is placed between two pins, one of which is moving and the other is attached to a load measuring arrangement. The moving pin is driven through a screw arrangement driven by a motor and a worm reduction gearbox. Provision has been made for automatically stopping the motor at the extreme positions of the moving pin. Two movable pins are provided, one for testing metric leas of 1 metre swift perimeter and the second for testing imperial leas of 1.5 yards swift perimeter.

Leather Testing Equipment

The resistance to abrasion of sole leather may be determined with the help of a drum type abrader (similar to NBS Abrader). In this test, an abrasive cloth strip of a specified grit is fixed over the circumference of a drum, which is rotated at a specified speed. The test specimen, in shape of a rectangular strip, is held on a metallic bar located above the drum such that its longer axis is perpendicular to the axis of the drum. When the metallic bar is pressed against the drum, the test specimen gets abraded. The number of revolutions needed to produce a depth of abrasion of 2.5 mm is determined and compared against that needed to produce a depth of abrasion of 2.5 mm in a standard rubber compound to obtain the abrasive index of the leather sample under test.Send Enquiry

Sole Adhesion Tester

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.

Yarn Evenness Tester

Visual determination of unevenness along the length of a yarn is carried out by wrapping it in equally spaced parallel wraps over a board and comparing the appearance of irregularities against standard rating photographs. To enable yarns of different thickness to be assessed, the spacing between the warps is suitably selected so as to give a clearly distinguishable pattern.

Crimp Rigidity Tester

Crimp Rigidity of a textured yarn gives a measure of its ability to recover from stretch. It is determined by measuring the percentage reduction of length of a skein of yarn immersed in water when a minor load replaces a major load. For measuring crimp rigidity, a skein of known number of strands is prepared from the package of yarn under test. This skein is then immersed in water filled in a glass jar with a load of 0.1 gdenierstrand suspended on it. The length of the skein is measured on a scale. The load is then reduced to 0.002 gdenierstrand by replacing the major load by the minor load and the reading on the scale observed. Crimp rigidity is calculated from the readings obtained under the major and minor loads
