An apparatus for winding continuous strands of material about rotating cores to form strand packages is provided with primary traversing mechanisms which impart a primary traversing motion to the strands as they are being wound on the packages whereby the strands progress and regress to define a series of bights. A secondary traversing mechanism is provided to impart a secondary traversing motion to the strands relative to the packages to advance the series of bights back and forth across the peripheral face of the packages. The primary traversing mechanisms each comprise a plurality of elongate straight elements which are supported in spaced-apart parallel relationship to define a cylindrical pattern. Each primary traversing mechanism is mounted on its axis of rotation so that the elongate elements extend at an oblique angle relative to the axis of rotation of the traversing mechanism.
An apparatus for winding continuous strands of flexible material about a core to form a package which apparatus includes a source of said strands, means for rotating said core about a first axis, a traversing mechanism rotatable about a second axis parallel to said first axis and adjacent to a peripheral surface of said package for imparting primary traversing motions to said strands as they are being wound on said package whereby said strands progress and regress to define a series of bights, and means for imparting a secondary traversing motion to the strands relative to the package to advance the series of bights across the peripheral surface of the package, the improvement comprising:
