    • A coating apparatus is provided in which entrained air flow of an applicator roll and a web is removed and occurrences of misting and coating irregularity are suppressed to thereby realize a uniform coating liquid film and a uniform coating state. A coating apparatus includes an applicator roll arranged to abut on another roll so as to form a nip portion therebetween and to transfer a coating liquid to be coated on a surface of a web passing through the nip portion. The coating apparatus further includes a coater head provided on an upstream side of the nip portion in a rotational direction of the applicator roll so as to supply the coating liquid onto a surface of the applicator roll and a boundary air remover provided between the nip portion and the coater head on the upstream side of the nip portion so as to prevent air from entering the nip portion. The boundary air remover includes a box part having an ejector ejecting an ejector gas on the surface of the applicator roll toward a direction reverse to the rotational direction of the applicator roll and also comprises a blade. The box part is constructed so as to cover a portion of the applicator roll.
    • 提供一种涂布装置,其中去除了涂布辊和纸幅的夹带空气流,并且抑制了雾化和涂布不均匀的发生,从而实现了均匀的涂布液膜和均匀的涂布状态。 涂布装置包括涂布辊,其布置成抵接在另一个辊上,以在它们之间形成辊隙部分,并将待涂覆的涂布液转印到通过辊隙部分的纸幅的表面上。 所述涂布装置还包括涂布机头,其沿着所述涂布辊的旋转方向设置在所述夹持部的上游侧,以将所述涂布液供给到所述涂布辊的表面,以及设置在所述辊隙部和所述涂布辊之间的边界空气除去器 所述涂布机头位于所述夹持部的上游侧,以防止空气进入所述夹持部。 边界空气去除器包括一个箱部件,其具有一个喷射器,该喷射器朝向与喷涂辊的旋转方向相反的方向在喷涂辊的表面上喷射喷射器,并且还包括一个叶片。 盒部分构造成覆盖涂抹辊的一部分。
