    • 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 selected filaments, and desirably, the filaments can be adhesive filaments. 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). At least a first, substantially continuous filament (24) can be directed onto the strand of material (22) along a corresponding, oscillating filament path (26) to form a first plurality of filament threads (28) which extend from opposed lateral side regions (30) of the strand of material (22). In particular aspects, at least a second, substantially continuous filament (24a) can be directed onto the strand of material (22) along a corresponding, oscillating filament path (26a) to form a second plurality of filament threads (28a) which extend from opposed lateral side regions (30) of the strand of material (22). Additionally, at least one air stream (32), and desirably a plurality of air streams are directed to operatively wrap the filament threads (28, 28a) around their corresponding strand of material (22).
    • 本发明提供了一种用于形成包括一个或多个选择性构造的材料束的制品的独特方法和装置(20)。 在具体方面,本发明可以提供一种用选择的细丝缠绕材料束的方法和装置,并且理想地,长丝可以是粘合长丝。 本发明的技术可以包括沿着指定的机器方向(34)以选定的速度移动一束材料(22)。 至少第一基本上连续的细丝(24)可以沿着相应的振荡细丝通道(26)被引导到材料束(22)上,以形成第一多个细丝丝(28),其从相对的横向侧面区域 (22)的股线(30)。 在特定方面,至少第二基本上连续的细丝(24a)可以沿着相应的振荡细丝通道(26a)被引导到材料束(22)上,以形成第二多个丝线(28a),其从 所述材料束(22)的相对的侧向侧区域(30)。 另外,至少一个空气流(32)和期望地多个空气流被引导以围绕其相应的材料束(22)可操作地包裹细丝线(28,28a)。
