The "Electric automatic twist-tester 17" allows to perform analyses on single and plied yarns

The electric twist-tester 17 determines the twist no. of double and single yarns through the inductive sensor that allows to determine automatically the end of test in compliance with UNI EN ISO 2060 and UNI EN ISO 2061.

Reading of S/Z twistings no.

Thanks to the gauge 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 device can be shifted by the operator along instrument basement and blocked at the desired length expressed in mm/inches (for example: 0 - 50 cm for the standard models) setting the exact distance between yarn clamps.
