The yarn hanks are wrapped simultaneously and prepared to define nextly their linear density with precision scales in compliance with International Standards as e.g. UNI 2060:97 and ASTM D 1907-01.
Manual Wrap reel 08 for yarn skeins holds up on a sturdy basement that assures the maximum stability during wrapping operations, and it is made of a painted stainless steel and chromed parts.
The reel can be of Metric type with a swift circumference of 1 meter length or in English type with a swift circumference of 1 or 1,5 Yard lenght referring to national and international Standards (UNI, ASTM, etc.).
The apparel is designed with a special traverse motion, duly designed to get a fine total lenght.
The traverse motion obtains a perfect and uniform yarn layer without doing any random overlaps during the wrapping operations and that can cause an increase of lenght error in total measurement uncertainty and linear density evaluations.
The certification type for manual wrap reel 08 for yarns has to be specified on request with the issue of calibration and certification report in hard and electronic copy from the Accreditation Body.
The accreditation practice focuses on the reel swift circumference lenght measurements in order to check the exact lenght measured between the reel rods front/rear points with a Vernier caliper whose certification copy has to be enclosed to final documentation.
During the instrument calibration the number of revolution turns are checked parallely with a certified electronic speedometer.
