PROBLEM TO BE SOLVED: To produce a high-strength nonwoven fabric by sufficiently bonding fibers of a web at both front face and rear face.SOLUTION: The nonwoven fabric production apparatus comprises: first and second rotary drums 1, 2 having a plurality of vent holes on a peripheral surface and arranged parallel to each other; introduction means 3 configured to introduce a web W to a peripheral surface of the first rotary drum 1; derivation means 6 configured to derive the web W that is wound on the peripheral surface of the first rotary drum 1 and then wound on a peripheral surface of the second rotary drum 2 from the second rotary drum 2; and hot air supply means 4 configured to blow hot air from inside or outside of the first and the second rotary drums 1,2 to the web wound on the first and the second rotary drums 1,2. The first and the second rotary drums 1,2 are arranged so that the rear face of the web W contacts with and is wound on the peripheral surface of the first rotary drum 1 and then the front face of the web W contacts with and is wound on the peripheral surface of the second rotary drum 2.SELECTED DRAWING: Figure 1 【課題】ウェブの表面及び裏面の双方を十分に接着して、強度の高い不織布を製造する。【解決手段】周面に複数の通気孔を有すると共に、互いに平行に配置された第１及び第２回転ドラム１，２と、ウェブＷを第１回転ドラム１の周面に導入する導入手段３と、第１回転ドラム１の周面に巻き掛けられた後、第２回転ドラム２の周面に巻き掛けられたウェブＷを、第２回転ドラム２から導出する導出手段６と、第１及び第２回転ドラム１，２に巻き掛けられたウェブＷに対して、第１及び第２回転ドラム１，２の内側又は外側から熱風を吹き付ける熱風供給手段４と、を備え、第１及び第２回転ドラム１，２は、ウェブＷの裏面が第１回転ドラム１の周面に接触して巻き掛けられた後、ウェブＷの表面が第２回転ドラム２の周面に接触して巻き掛けられるように配置される。【選択図】図１
