About Lea Strength Tester

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.

In case of pendulum type testers the load exerted on the lea is measured with the help of the deflection of a pendulum and is indicated on a circular dial having provision for indicating the maximum load applied before failure of lea occurs. Load measurement is done in three ranges. The ranges can be changed by adding disc weights to a pin fitted at the outer end of the pendulum arm. Overload protection to automatically stop the motor if the load exerted goes above the maximum capacity of any range is also provided.

In case of electronic type testers the load is measured with the help of a load cell and digital indicator having a peak hold and overload protection facility.

The apparatus is finished in shore blue matalic painting and bright chrome or zinc plating to give it a corrosion resistant finish.

Efficient Yarn Testing for Consistent Quality

The Lea Strength Tester is engineered for laboratories and textile manufacturers seeking reliable measurement of yarn strength. Offering a direct scale reading and a manual method for recording breaking strength, it ensures each test is straightforward and repeatable. Its sturdy, powder-coated or painted frame is built for durability in demanding environments, and the system supports ambient testing for both humidity and temperature. Designed for lea specimens of 120 yards, it accommodates one test at a time, granting precise control for detailed textile analysis.

Versatile Operation Modes

This strength tester is available as either a hand-operated or a motorized unit, catering to various user needs. The hand-operated model offers simplicity and independence from power fluctuations, while the motorized variant increases testing consistency for high-throughput labs. Both designs guarantee the same 1% accuracy across the full scale, making the instrument adaptable to various testing settings and requirements.

FAQs of Lea Strength Tester:

Q: How is the Lea Strength Tester used to measure yarn strength?

A: To measure yarn strength, a yarn lea (typically 120 yards in length) is clamped to the tester with a 1.5-yard clamping length. The operator then applies load using either the hand-operated or motorized system, depending on the model. The load is directly read on the scale when the yarn breaks, and the maximum breaking strength is manually recorded.

Q: What materials and specimen sizes are compatible with this tester?

A: The instrument is designed specifically for testing leans of yarn, with recommended specimen sizes of 120 yards in length. It is suitable for a variety of yarn types, making it ideal for textile industry quality control and research.

Q: When should I opt for a hand-operated versus a motorized model?

A: Hand-operated models are preferable for basic or lower-volume testing environments, where manual control is sufficient. For higher volume applications or when tester consistency and operator ease are priorities, the motorized model is recommended for its efficient, repeatable operations.

Q: Where is the Lea Strength Tester typically used?

A: This tester is mainly used in textile laboratories, manufacturing units, research institutes, and quality control departments in the textile industry. Its portability and moderate size allow it to be installed in standard laboratory settings.

Q: What is the benefit of using this tester for textile manufacturers?

A: The primary benefit is the precision measurement of yarn strength, essential for ensuring product quality and consistency. The testers direct scale display, manual recording, and compliance with international standards make it a reliable tool for both routine testing and quality audits.

Q: How does the tester comply with industry standards?

A: The Lea Strength Tester is designed according to IS 1671 and ASTM D1578 standards, providing confidence in the accuracy and repeatability of its results for industry and regulatory compliance processes.
