摘要:
The present invention relates to a novel method and apparatus for producing nonwoven fabrics. Generally, in production of nonwoven fabrics, in order to obtain a nonwoven fabric with a wide width, it has been impossible to obtain a uniform nonwoven fabric unless a large number of spinnerets ejecting fibers are installed in the width direction of the nonwoven fabric. The present invention relates to a novel method and apparatus for producing nonwoven fabrics capable of easily increasing the width of the fabric even when only few spinnerets are used. The method for producing nonwoven fabrics according to the present invention is characterized in that a group of fibers entrained with a high-speed fluid is ejected from a nozzle rotating around the axis of a substantially stationary cylindrical support as its rotational axis on the inner peripheral surface of the cylindrical support and is laminated thereon in the form of a web and furthermore, the web is resiliently pressed under a heating condition via a roller revolving on the inner peripheral surface of the cylindrical support around the revolutional axis which is the same as the rotational axis of the rotating nozzle and then, the web is taken up from the cylindrical support while it is slipped. In addition, the apparatus according to the present invention relates to an apparatus practicing the method.
