Abstract
A yarn profile analyzer and method in which the yarn is moved under substantially constant tension through an imaging area including a light source and a spaced light sensing array. The width of closely spaced portions of the yarn passing through the imaging area is then determined from the array output, and the widths are stored and then analyzed for a variety of parameters.
