Presto Yarn Tensile Testing Machine is used to evaluate the tensile strength of single or doubling yarn with peak value. This helps to determine the breaking force, toughness, and elongation of yarn. The machine accurately determines the stress characteristics with a constant rate of extension. The tool is helpful and beneficial for the yarn industries, besides PET and packaging, textile industries, rubber and plastic industries.
Yarn tensile testing machine comprises of the upper jaw and lower jaw where yarn testing sample is placed. The lower jaw moves at the designated speed with the help of the standard motor, which is installed using a CE standard electrical wires. The motor stresses the lower jaw. The upper jaw does not move and remains stationary. The machine is designed with heavy mild steel ensuring significant stability and providing the high-quality testing results with over travel and overload protection.
The device is based on the principal of constant rate of transverse (CRT) and is widely used for measuring the tensile strength of materials. The machine ensures the accuracy in determining the tensile strength of yarn and provides a safe and reliable operation. The instrument is supplied with two sets of grips and provides a grip to grip separation between 25 to 700 mm. This is the best-suited device to check the tensile strength and elongation of yarn.
