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. 

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.

• 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.

Adjustable speed of the rotating clamp by means of a special electronic variator.

Suitable for both single and twisted yarns (S & Z).

Digital reading. Original model complete with optical tracer and warning light to signal the starting and stopping "zero".

Accuracy: +/1 rotation.

Highly sensitive "Elongation" indicator with built-in rapid clamp.

Clamp and handle rotation ratio 10 : 1.

Adjustable distance between clamps from 0 to 50 cm and from 0 to 20 inches.

New computerized and automatic version of the well-known ATTRIFIL. Electronic instrument for measuring the friction coefficient in a wide variety of yarns and threads. The friction is measured in a continuously recorded process by two highly sensitive measuring heads. The precise measurement of the coefficient of friction is of vital importance in downstream processes such as knitting, weaving or sewing.

Main technical features of ATTRIFIL II are:

• Automatic testing from a single package/bobbin up to 999 tests without operator attendance.
• Pre-selection of the yarn length to be measured.
• Pre-selection of the yarn length between two consecutive measurements or random testing.
• Operating software for IBM or other compatible P.C. (P.C. and printer supplied on request only).
• Integrated Data Bank storage.
• Electronic input (T2) and output (T1) tensiometers.
• Adjustable yarn speed from 0 to 300 m/min.
• Automatic low decibel sucking device.
• Slow start-up speed of rollers.
• Reduced dimensions,
• Complying with EC safety regulations.
• Coefficient of friction indicated for both each single bobbin and a group of tests.
• Power supply: 220 V - 50 Hz / 110 V - 60 Hz single phase.
• Compressed air 6 Bar.

Optional:

On request ATTRIFIL II code 233B can be interfaced with the Auto Cop Changer code 299A to automatically perform tests on 24 different bobbins at a time.

For objective and quick counting of neps and trash in slivers from carding, combing machines and drawing frames.
Collected data is essential for the determination of raw material quality and the wear conditions of the clothing on both carding and combing machines.
Being very lightweight (K9 20), it is easily trasportable and can be used near to the production machine.
The device is fitted with a suction system, for use with a 220 V 50/60 Hz supply.
Principle features:

• Performance speed: the analysis of 1 meter sliver sample takes less than two minutes.
• Data repeatability: manual preparation of sample does not influence final result.
• Reading accuracy: besides the classical counting of neps over 0.7 mm, it is also able to read neps > 0.5 mm. As concerns trash, it is divided in two classes: >0.25 mm, >0.5 mm.

The device has a display for single data reading of Neps and Trash.
Optional: possibility for linkage to a printer for the reading of statistical data (average, standard deviation, CV%) every 5 tests. Fitted with RS232C output.
