Abstract
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).
