Abstract (en)
[origin: EP1321412A2] The process creates a crossing angle between 15-28 degrees in the middle zone (30), which is produced with this angle across more than 50% of the total winding width. The crossing angle in the middle section is at least 8 degrees smaller than the maximum angle in the edge zones (28,29). Yarn tension is reduced as the package diameter increases. <??>An Independent claim is made for the resulting crosswound package.
