The strength of a yarn depends to a great extent on the amount of twist imparted. Accurate determination of this physical property is very importance in assessing the quality of a yarn. The amount of twist given to a yarn is usually determined by untwisting a known length of yarn and  finding the number of rotations of one of its ends relative to the other by remove the twists  completely. Ramp Twist Tester  (Double Yarn) is  the appropriate equipment for the determination of twists of a double yarn .

Ramp Twist Tester Double Yarn has a set of clamps; one of which is rotating and the other is fixed. The rotating clamp is driven by hand. Specially designed a five-digit re-settable revolution counter to count the number of twists. The fixed clamp is mounted on a jewel bearing with a lever having a sliding weight to give the desired tension to the yarn. A special scale is  attached vertically on the clamp stand for measuring the tension on the yarn. The fixed clamp assembly can be moved over a guide bar for setting the required test length of yarn. The Test Length is indicated on a calibrated strip scale fixed to the base against a pointer attached with the moving assembly. A magnifying glass is provided to check the opening of the twists in the yarn during untwisting process. The equipment is meticulously finished in Blue PU paint.  The base of the apparatus is meticulously finished in Blue Paint and all other parts are of Stainless Steel.
