Summary:PROBLEM TO BE SOLVED: To provide a nonwoven cloth manufacturing apparatus capable of preventing a width reducing phenomenon from occurring when a web is transferred between a pair of suction drums.SOLUTION: A second suction drum 4 is placed to meet following conditions: for a horizontal direction, an apex 32, which is located on a downstream side in a horizontal direction on outer peripheral surface of the second suction drum 4, is positioned on more downstream side in a horizontal direction than a tangent m extending in a vertical direction of an apex 42, which is located on a downstream side in a horizontal direction on outer peripheral surface of the first suction drum 3, or on the tangent m; a horizontal distance Lbetween respective axis lines of the first suction drum 3 and the second suction drum 4 has a relation with an outer peripheral diameter Dof the first suction drum and an outer peripheral diameter Dof the second suction drum to represent L≤0.7(D+D); and for vertical direction, the axis line of the second suction drum 4 is located at a position lower than the axis line of the first suction drum 3 and a vertical distance Lbetween the respective axis lines of the first suction drum 3 and the second suction drum 4 has a relation representing L≤D. 【課題】ウェブを一対のサクションドラム間で受け渡す際の幅入り現象の発生を抑制可能な不織布の製造装置を得る。【解決手段】第２サクションドラム４を、水平方向について、第２サクションドラム４の外周面における水平方向の下流側に位置する頂部３２が、第１サクションドラム３の外周面における水平方向の下流側に位置する頂部４２の、鉛直方向に延びる接線ｍよりも水平方向の下流側又は該接線ｍ上に位置し、且つ、第１サクションドラム３と第２サクションドラム４の両軸線間の水平方向距離Ｌ1が、第１サクションドラムの外周径Ｄ1と第２サクションドラムの外周径Ｄ2との関係でＬ1 ０．７（Ｄ1＋Ｄ2）となる位置に配設し、鉛直方向について、第２サクションドラム４の軸線が第１サクションドラム３の軸線よりも下方に位置し、且つ、第１サクションドラム３の軸線と第２サクションドラム４の軸線との間の鉛直方向距離Ｌ2がＬ2 Ｄ1となる位置に配設する。【選択図】図２
