PROBLEM TO BE SOLVED: To provide a needle punching method for fibers web capable of increasing continuous drawing out speed with a slight cost and an apparatus therefor. SOLUTION: In a method for needle punching of fibers web 3 by a needle 2 repeatedly piercing through the fibers web 3 and an apparatus therefor, the fibers web 3 is drawn out from the needle punching range at a continuous drawing out speed while being elongated during the time when the needle 2 is hooking om the fibers web 3 and while being accelerated during the time when the needle 2 is not hooking on the fibers web 3. In order to increase the drawing out speed, the drawing out speed from the fibers web 3 is accelerated to a speed exceeding that before the continuous drawing out during the time when the needle 2 is not hooking on the fibers web 3 after the needle punching. |
