Twist Tester

Model No. YTE001

Twist Tester for yarns measures the TPI and TPM of single and multiple plied yarns. Different models are available. The system consists of a set of clamps, one of which rotating and the other fixed. The rotating clamp is driven by hand through a speed increasing arrangement (by motor in motor operated model) and a five digit reset able revolution counter (digital counter in motor operated) to count the number of twists. The fixed clamp is pivoted on jewel bearings and carries of a pendulum arm having a sliding weight to give the desired tension to the yarn. The fixed clamp assembly can be moved over a guide bar for setting the required test length of yarn which is indicated on a strip scale fixed to base against a pointer attached to the moving assembly. A viewing plate and a magnifying glass are provided for accurate determination of the end point. A dissecting needle for ascertaining complete removal of twist is supplied as standard accessory with the equipment. The various components are fixed on a rigid base strength and durability. All parts of the instruments are either painted or bright chrome plated to give a corrosion resistant finish and highly aesthetic appearance.
