Twist Tester
Model 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.
