The Twist-tester 17 determines the twisting no. thanks to the inductive sensor that allows to determine automatically the end of tests in accordance to UNI EN ISO 2060 and manually by the operator according to UNI EN ISO 2061.
Thanks to the dial counters mounted on board it is possible to check the twistings no.; the counter on the left shows the read-out of the thousands and hundreds of turn, while the right one the tenths and units of turn.
The control head panel allows to set manually the S or Z rotation direction, to select the test methods (e.g. untwist-retwist, direct counting, ..) and to adjust rotation speed during test performances through a potentiometer.
On the left side the movable elongation device hosts a fixed viewer scale, the elongometer, equipped with elongation index, while a yarn pretension group can be loaded manually according to yarn specifications (tex) under examination just adding required pretension of 1 g/tex or according to the reference Standard.The meauring scale shows clearly the elongation of yarn sample during untwist/retwist performances on a double scale expressed in mm/inches. The movable equipment group can be shifted along a fixed drive on instrument basement and fixed at the desired length expressed in mm/inches (e.g. 0 - 50 cm for the standard models) defining the exact distance between sample fixing clamps.
