Latest Patents

One of his latest patents is for a "Traverse roll for filament yarn cross winding apparatus." This invention concerns an improved yarn package, process, and apparatus. The improved package is particularly useful in automated processes for making melt spun yarn. The invention comprises a cross wound package of melt spun flat filament yarn characterized by the yarn's outer end being pile wound in a compact bunch on the package's surface. The yarn end includes at least twenty pile turns, with upstream pile turns partly underlapping the downstream pile turns. Additionally, modifications to conventional processes and apparatus for winding yarns are included to facilitate the creation of such packages, especially at speeds greater than 3000 meters per minute.

Another significant patent is for "Apparatus for individual yarn selection particularly in donning multicop." This invention features an improved yarn guide assembly designed to select yarns individually from a group during the donning of a multicop winder. The assembly includes guide members shaped to receive a yarn only if it lies in a unique plane. The guiding surfaces of the guide members beyond the gaps are inclined and partially face the direction from which the yarns approach, enhancing the selection process.
