The Yarn Board Winder is an electronic conical board testing machine which can rotate a yarn board end-over-end at a constant speed. A reference table is provided in ASTM D 2255 to specify the proper spacing for the traversing mechanism. The traversing guide is used to advance the yarn evenly under tension across the board as it is wound. When the yarn is completely wound the testing device automatically stops.
The test specimen is now available for acceptance grading and can be given a yarn appearance grade determined from visual analysis.
There are several terms to describe this device such as a Taper Board inspection machine or an Electrical Conical commonly referred to as a Motor Driven Taper Board.
