​Wrap-Reel Length Measuring Instrument

Applicable Standards

1. GB/T 4743: This is a standard regarding the determination of yarn linear density. It may specifically be GB/T 4743 - 1995 "Determination of Yarn Linear Density - Wrap-Reel Method" or a similar version. This standard stipulates the methods and requirements for measuring yarn linear density using equipment such as a wrap-reel length measuring instrument.

2. GB/T 14343: This is a standard for the test method of the linear density of chemical fiber filaments, which is also applicable to the application of the wrap-reel length measuring instrument in the testing of chemical fiber filaments.

3. GB/T 6838: This is a standard for the test methods of sewing threads, which may include provisions for certain tests using a wrap-reel length measuring instrument.

4. FZ/T 54001: This is a specific standard in the textile industry, which may involve the test methods of yarns or fibers and is also applicable to the wrap-reel length measuring instrument.

Main Parameters

1. Number of movable tubes: Refers to the number of tube yarns or cop yarns that a wrap-reel length measuring instrument can take at one time. The common range of the number of movable tubes is from 1 to 6, but the specific number may vary depending on the model.

2. Yarn frame circumference: Refers to the circumference of the yarn frame of the wrap-reel length measuring instrument, which is used to determine the length of the yarn taken. The common yarn frame circumferences are 1000mm ± 0.5mm or 1000mm ± 1mm, depending on the model and accuracy requirements.

3. Yarn frame rotational speed: Refers to the rotational speed of the yarn frame of the wrap-reel length measuring instrument, usually expressed in revolutions per minute or millimeters per minute. The yarn frame rotational speed is adjustable, and the common speed adjustment ranges are from 30 to 250 revolutions per minute or from 30 to 280 millimeters per minute, depending on the model and testing requirements.

4. Tension range: Refers to the tension range that the wrap-reel length measuring instrument can apply when taking the yarn. The common tension range is from 0 to 100cN, depending on the model and testing requirements.

5. Pre-set coil number range: Refers to the range of the number of yarn coils that the wrap-reel length measuring instrument can pre-set. The common pre-set coil number range is from 2 to 9999 coils, depending on the model and accuracy requirements.

6. Shuttle reciprocating stroke: Refers to the reciprocating moving distance of the yarn frame when the wrap-reel length measuring instrument takes the yarn. The common shuttle reciprocating strokes are 35mm ± 0.5mm or 35mm ± 1.5mm, depending on the model and accuracy requirements.

7. Overall dimensions and weight: The overall dimensions and weight of the wrap-reel length measuring instrument vary depending on the model, but it is usually relatively large in size and heavy in weight. The common overall dimensions may be 780mm × 660mm × 480mm (length × width × height), and the weight may be around 40kg.
