Electronic Twist-tester 61

The electronic twist-tester 61 is the advanced instrument to determine the twists number of yarns

Manufactured by Branca Idealair and designed to determine the exact number of twist for single e.g. spun or filament yarns, plied, cabled, multi-level, Open-End yarns and other yarns typology in accordance to national and International Standards.

The electronic twist-tester 61S is compliance to reference standards UNI 9069, UNI EN ISO 2060, ISO 2061, ASTM D-1423, ASTM D-1422

The Electronic Twist-tester 61 is designed to determine the twists number with high accuracy of +/- 0,1 turn, suitable both for single, double and multi-level yarns with variable lengths from 0 to 50 cm in standard models or up to 1 or 2 mt for special ones.

The Electronic Twist-tester 61S is a user friendly device for all operators thanks to its comfortable 5" display with Touch Screen that allows operators to choose the correct test methods for yarns available in an advanced interface as e.g. untwist-retwist operations and other procedures already included in the STANDARD model as indicated here below:
- SINGLE, untwist-retwist suitable for single yarn;
- DIRECT COUNTING, only yarn untwist;
- DUAL F1, separation of plied yarns (2 ends yarn) + DUAL F2, for determination of turns no. of last yarn end;
- SCHUTZ METHOD, according to the 2nd Appendix New “double test check” worked out by Messrs. M.KUENY, H.LE CHATELIER and R.A. SCHUTZ;
- MANUAL CONTROL, motor control set directly by the operator with turns count reading;

supplementary test methods are implemented only in the PRO model :
- MULTI-LEVEL, suitable to determine the turns no. of plied yarns up to 5 levels;
- MULTI-BOBBIN, direct analysis on Single, Direct Counting, Dual, Multi-level yarns following the operator step by step during all test procedure;

The test bullettin is printed from the ASCII Printer supplied on request, where the operator can input data and notes as additional data, e.g.:
- Company;
- Instrument no.;
- Tension applied in grams during the test;
- Notes;

Test report includes also info about:
- Direction of twist (SZ or ZS);
- Sample length, expressed in cm or inches;
- Saved memory up to 20 results per test method;

Statistical evaluations:
- Minimum;
- Maximum;
- Average;
- Delta (Max-min);
- Coefficient of Variation (CV%);
- Standard Deviation (ST.Dev%);

Stored data can be expressed both in TPM (Twist per meter) or in TPI (Twist per Inch) always chosen by the operator; the measure unit chosen are shown on test report;

During the test the HMI touch screen shows data and evaluation data, e.g.:

For STANDARDmodels:

For SPECIAL models:




TWIST04: software for external PC across USB communication allows to manage automatic statistical evaluations of results, trend analyses, Macros and Operation formula with Microsoft Excel;
