Description & Specification for Lab Tenders
Detailed product overview for Twist Tester — suitable for institutional purchases and international tender submissions.
Technical Specification
Complete technical data, dimensions, capacity and performance parameters for Twist Tester.
The Twist Tester consists of a set of clamps, one of which is rotating and the other fixed. The rotating clamp is driven by hand through a hand wheel and gear arrangement. A five-digit re-settable revolution counter counts the number of rotations of the rotating clamp.
The fixed clamp is pivoted on jewel bearings and carries 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 the 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. The base is finished in shore blue matalic painting, while all other parts are bright chrome plated to give them a corrosion resistant finish.
A motorized version of the tester is also available. It uses a synchroset type motor and a direction-changing switch for selecting proper untwisting direction.
