Manual twister tester

Tool to determine the number of torsions on the single yarns, S, Z, and Open End bended.

The available tests are the classic ones, such as the de-torsion and the re-torsion on single yarns, the direct one for the de-torsion of bended yarns and filaments.
It is possible to set the distance between the clamps from 1 and 50 cm, corresponding to 0,5 and 20 inches. A very precise elongation device measures the variation of the lengthening from 0 to 100 mm. The standard equipment provides a set of 7 weights for pre-tension between 1 and 50 gr, but it is also possible to have heavier weights as an optional.
