Electronic Semi-Automatic Twist Tester "TWISTRONIC" - Code 2530A 

Suitable to determine twist of both single, twisted and Open End yarns.

The principle characteristics of this model are:

• Automatic and pneumatic yarn clamping system once the correct pretensioning is reached.
• Automatic start-up following clamping.
• Complete with software and integrated printer which provide the analysis and printout of the following data: mean value, min. value, max. value, coefficient of variation %, range and standard variation.
• Three preselection text methods: 1.) Traditional Method: untwisting, retwisting for single yarns. 2.) "Schutz" Method: untwisting, retwisting, and double counter-check. This test is used mainly on O.E. spun and worsted wool yarns. 3.) Direct Method: untwisting for plied yarns, threads and multi-filament yarns.
• RS232C serial port.

Electronic Automatic Twist Tester "TWISTRONIC" - Code 2530B (+ Code 299A - optional)

 

An innovative model in the generation of Twist Testers.

This version enables at reasonable costs to perform automatically serial twist test measurements on single packages without operator attendance.

Main technical features:

• Automatic yarn clamping system
• Automatic twist testing of single yarns following the untwisting and retwisting method.
• Automatic twist testing of Open End yarns following the Schutz method.
• Semi-automatic testing following the direct method of untwisting for both plied and multi-filament yarns.
• Automatic single package twist testing from 1 to 999 tests.
• Twist testing either every X meters of yarn, to be selected, or at random distance, on choice.
• Complete with software and integrated printer which provide the analysis and printout of the following data: twist mean value, min. value, max. value, C.V.%, Range, standard deviation and alfa coefficient.
• Serial port RS232C to connect the unit to a P.C. for Data Bank.
• Three preselection test methods: 1.) Traditional Method: untwisting, retwisting for single yarns. 2.) "Schutz" Method: untwisting, retwisting, and double counter-check. This test is used mainly on O.E. spun and worsted wool yarns. 3.) Direct Method: untwisting for plied yarns, threads and multi-filament yarns.

Optional: Auto Cop Changer Code 299A

The modularity of this new generation of MESDAN-LAB Electronic Twist Testers achieves its maximum expression in the connection of the "Auto Cop Changer" (A.C.C.) with 24 positions (Code 299A) to the Automatic Electronic Twist Tester. The combination of these technologies enables up to 999 tests on each of 24 different packages (cops) to be obtained without further operator attendance after the initial presetting.

Additional features of this model are:

• Package change automation at the preselected number of tests.
• Possibility to control different batches previously programmed keeping the results distinct.
• Simplicity of operation coupled with maximum versatility.
