• TWIST TESTER – MANUAL (FOR SINGLE YARN)
TWIST TESTER – MANUAL for Single Yarn - is a Yarn Testing Equipments used for accurate measurement of TPM (Twist per meter) of the twisted yarn.

The strength of a yam and other properties of fabrics depends to a great extent on the amount of twist given to it.  Thus accurate determination of this factor is of prime importance in assessing the quality of any yarn.  The amount of twist given to a yam is usually determined by untwisting a known length of yam and finding the number of rotations of one of its ends relative to the other which remove the twists completely.  The equipment used for determination of twists of a yam is known as Twist Tester

 

The 'VGOTECH' Twist Tester for yarns consists of a set of clamps, one of which is rotating and the other fixed.  The rotating clamp is driven by hand through a speed increasing arrangement and a five digits re-settable revolution counter 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 yam. The fixed clamp assembly can be moved over a guide bar for setting the required test length of yam 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 cast iron base for strength and durability.  The base is finished in off white synthetic stoving enamel paint and all parts bright chrome plated to give a corrosion resistant finish and highly aesthetic appearance.

 

The motorised version of the tester is also available using a universal motor and a direction changing mechanism for selecting proper untwisting direction check.
