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). La presente invencion proporciona un metodo y un aparato distintivos para formar un articulo el cual incluye uno o mas hilos de material configurados selectivamente. En aspectos particulares, la invencion puede proporcionar un metodo y un aparato para envolver un hilo de material con un filamento seleccionado, y deseablemente, el filamento puede ser un filamento adhesivo. La tecnica de la invencion puede incluir el mover un hilo de material a una velocidad seleccionada a lo largo de una direccion de la maquina designada. Un filamento esencialmente continuo puede ser dirigido sobre el hilo de material a lo largo de una trayectoria de filamento oscilante para formar una pluralidad de hilos de filamento que se extienden desde las regiones de lado laterales opuestas del hilo de material. Una corriente de aire es dirigida para envolver operativamente los hilos de filamento alrededor del hilo de material.
