Abstract
In order to increase the yarn tension between a winder and a bobbin creel, the yarns are returned from a first yarn tensioner to the inlet of a second adjacent yarn tensioner in the row. The rows of bobbins which are associated with the second yarn tensioners remain without bobbins. In order to facilitate a change in direction when dealing with sensitive yarns at the second yarn tensioner, a direction-changing roller is disposed at the inlet thereof.
