It is the Lea strength testing machine that is commonly used to determine yarn strength and elongation. The friction force rendered to this machine yarn reduces the sensitivity of the test to detect weak spots in the yarn. So weaker yarns can also produce less power. Also tests the yarn for suitability for final use. Its test force range is from 0 to 2500N. The effective distance between upper and lower yarn hook of this machine is 50-550mm
