Method of and apparatus for manufacturing a web having filaments aligned in a transverse direction

A method of manufacturing a transversely aligned web in which filaments are aligned in a transversely direction, comprising the steps of:

• preparing a spinning means having a plurality of nozzles arranged in parallel with an machine direction of a conveyer for extruding molten polymer in the form of filaments and a high-speed fluid blowing unit for blowing a high speed fluid in a direction parallel with the extruding direction of the filaments to thereby attenuate the filaments extruded from said nozzles, and at least one air stream vibrating means for cyclically changing the flowing direction of the high speed fluid blown from said high-speed fluid blowing unit toward the direction cross to the machine direction of said conveyor;
• extruding the molten polymer in the form of the filaments from said nozzles;
• blowing said high-speed fluid to attenuate the filaments extruded from said nozzles by a frictional force applied by said high-speed fluid;
• and,
• changing cyclically the flow direction of said high-speed fluid by said air stream vibrating means to thereby while cyclically changing a movement of said filaments in the direction cross to said machine direction, accumulating said filaments onto said conveyor.
