The apparel can determine the twist no. and twist direction of single and folded yarns , monofilament yarns, multifilament yarns, OE yarns composed of natural or synthetic fibers
Twist-tester Branca 61S is designed to determine the twists per meter (tpm) or twists per inches (tpi) of all types of yarns as e.g. single, monofilament, folded yarns, multifilament yarns,Open End, spun yarns, synthetic yarns, etc..
The reading accuracy has been improved at ± 0,1 twist and yarn sample can be tested easily setting the distance between the clamps from 1 to 50 cm in standard versions through the movable equipment installed on board or until 1 or 2 m for special models mainly used for tyre cords application, thus high-quality nylon and polyester yarns.

The electronic twist tester 61S is easy to use thanks to the user-friendly hmi touch screen that allows to select the test selection to use for the big variety of yarns:
| SINGLE | single yarn test means Untwist-Retwist method of single spun yarns in S or Z twist direction as described in UNI 2061, ASTM D1422; |
| DIRECT | direct counting test method means only untwist of yarns reaching the straight section of a yarns according to ASTM 14232/1423M; |
| DUAL | test method suitable for double or plied yarns; |
| SCHUTZ | suitable for Open End yarns according to the 2nd Appendix New “double test check” worked out by Messrs. M.KUENY, H.LE CHATELIER and R.A. SCHUTZ; |
| MANUAL | motor control digitally commanded by the operator and real time read-out of real twistings; |
Additional test methods are implementable only in the Twist tester 61S PRO software version:
| SLIPPAGE TEST METHOD | test method used to determine when yarn fiber slip off applying different pretension weights; |
| MULTIFILAMENT TEST METHOD | test method suitable to determine the twistings no. of folded yarns up to 10 yarn levels. |
| GUIDED ANALYSES | operator led by the indications on the screen and test indexing, can perform multiple analysis on Single, Direct Counting, Dual, Multi-level yarns following instructions shown on display step by step; |
Test report includes additional info about:
Other statistical evaluations:
Saved results are expressed both in TPM (twist per meter) or in TPI (twist per inch).
The measure units are indicated on test report.
During the test, the HMI touch screen shows data and evaluation data, e.g.:
Application software TWIST4.0: for PC use through USB serial port communication, that allows to do automatic statistical evaluations on test results, generation of trend graphs, macro plugins and math formulas;
