The present invention provides a distinctive method and apparatus (20) for forming an article which includes one or more selectively configured strands of material. In particular aspects, the invention can provide a method and apparatus for wrapping a strand of material with a selected filament, and desirably, the filament can be an adhesive filament. The technique of the invention can include a moving of a strand of material (22) at a selected speed along an appointed machine-direction (34). A substantially continuous filament (24) can be directed onto the strand of material (22) along an oscillating filament path (26) to form a plurality of filament threads (28) extending from opposed lateral side regions (30) of the strand of material (22). An air stream (32) is directed to operatively wrap the filament threads (28) around the strand of material (22). L'invention concerne un procédé et un dispositif (20) particuliers pour la réalisation d'un article comprenant un ou plusieurs fils de base configurés de manière sélective. Selon certains modes de réalisation, l'invention concerne un procédé et un dispositif pour envelopper un fil de base avec un filament sélectionné, le filament pouvant être idéalement un filament adhésif. La technique de l'invention peut inclure le déplacement d'un fil de base (22) à une vitesse sélectionnée dans un sens de machine défini (34). Un filament pratiquement continu (24) peut être amené sur le fil de base (22) le long d'un chemin de filament oscillant (26) afin de former plusieurs fils continus (28) s'étendant à partir de zones latérales opposées (30) du fil de base (22). On utilise un flux d'air (32) pour envelopper activement les fils continus (28) autour du fil de base (22).
