    • A method for forming compression-bonding portions in a continuous body of a web member including a fiber bundle, while conveying the continuous body in a predetermined direction set as a direction of conveyance, the fiber bundle being continuous in the predetermined direction while a fiber direction is set along the predetermined direction, the compression-bonding portions being formed at intervals in the direction of conveyance. The method includes: rotating a rotator around a rotation axis along a CD direction intersecting with the direction of conveyance, while holding the continuous body of the web member on an outer peripheral surface of the rotator, to convey the continuous body of the web member in a direction of rotation of the rotator set as the direction of conveyance; compressing a formation target part of each of the compression-bonding portions in the continuous body of the web member, using a compression-bonding member and the rotator, when the formation target part passes through a position of the compression-bonding member disposed at a predetermined position in the direction of rotation, to form the compression-bonding portions; and pressing the continuous body of the web member to an inside in a radial direction of rotation of the rotator using a pressing member, while avoiding forming the compression-bonding portions in the continuous body of the web member, the pressing member being disposed to be opposed to the outer peripheral surface of the rotator, at a position upstream in the direction of rotation from the compression-bonding member.
    • 一边在包含纤维束的纤维网构件的连续体上形成压接部的方法,一边以规定方向输送连续体作为输送方向,纤维束在规定方向上连续,纤维方向 沿着所述预定方向设置,所述压接部分在所述输送方向上间隔地形成。 所述方法包括:在将所述连结体的所述连续体保持在所述转子的外周表面上的同时,沿着与所述输送方向交叉的CD方向围绕旋转轴旋转转子,以将所述连结体的连续体输送到 旋转体的旋转方向设定为输送方向; 当形成目标部分通过布置在压接元件的位置处的压接元件的位置时,使用压接元件和转子压缩卷材元件的连续体中每个压接部分的形成目标部分 在旋转方向上的预定位置处形成压接部分; 并且在避免在腹板构件的连续体中形成压接部的同时,利用挤压构件将腹板构件的连续体压向旋转体的旋转的径向方向的内侧,挤压构件布置成 在旋转体的外周面的相对于压接部件的旋转方向的上游侧的位置,
