B-TEX^TM 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 motor through push button arrangement and a five-digit re-settable revolution counter to count the number of twists. The fixed clamp has a knob by which yarn is clamp. The required dead weight can be placed by tightening elastic 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.

The various components are fixed on a rigid iron plate base. The unit is nicely finished and all parts are bright chrome plated to give a corrosion resistant finish.
