The Twist Tester measures the TPI (turns per inch) and TPM (turns per metre) of single and multiple yarns, and is available in several models. The system comprises a set of clamps, one rotating and one fixed. The rotating clamp is driven by hand through a speed-increasing arrangement (or by motor in the motorised model) with a five-digit resettable revolution counter (digital in the motorised version) to count the number of turns. The fixed clamp is pivoted on jewel bearings and carries a pendulum arm with a sliding weight to apply the desired tension to the yarn. The fixed-clamp assembly can be moved along a guide rod to set the required test length of yarn, shown on a strip scale against a pointer attached to the moving assembly. A viewing plate and a magnifying glass are provided for accurate determination of the end point, and a dissecting needle for confirming complete removal of twist is supplied as a standard accessory. The components are fixed on a rigid base for strength and stability, and all parts are either painted or bright chromed for a corrosion-resistant, attractive finish.
