Abstract An apparatus, method and package are provided for producing and winding bundles of filamentary material to achieve good split efficiency on removal of the plurality of bundles from the package for further processing and to produce a package of wound bundles of filaments having good edges. The apparatus has a filament forming means, an applicating means for applying chemical treating compositions to the filaments, gathering means to gather the filaments into a plurality of bundles of filaments, a rotatable winder to attenuate and wind the bundles, a slotted traversing guide, a reciprocating means, and contact means at each end of the recipro- cating stroke of the traversing guide. The slotted traversing guide has more than one slot where the terminal portions of the slots have curved ends to retain a bundle of strands and are located directly behind the terminal portion of the preceeding slot. The slotted traversing guide deposits the bundles of filaments on the rotating winder and as the tra- versing guide approaches the point at which it reverses to traverse in the opposite direction parallel to the axis of rotation of the winder the bundles above or below the traversing guide contact a contacting means to restrain the traversing movement of the contacted segment of the bundles to apply tension to the bundles of filaments being wound onto the winder. This additional tension assists in producing squarer edged packages having good split efficiency.
