    • The application describes compressive treatment of a web employing a pair of drive rolls defining a nip for driving the web forward and retarder means for retarding the forward progress of the web to cause compaction of the web in the cavity between the rolls downstream of the nip. The web is driven forward by rolls having driving surfaces each comprising a series of principal web-gripping grooves extending in only one direction helically about the roll axis. At the nip line of the rolls the angle of the grooves of one roll are inclined positively relative to the direction of travel of the web. The angle of the other roll is inclined negatively relative to the direction of travel of the web.
    • 该申请描述了一种纸幅的压缩处理,该纸幅采用一对限定用于驱动纸幅向前的辊隙的驱动辊和用于延迟纸幅的向前推进的阻滞器装置,以引起纸幅在辊隙下游的辊之间的空腔中的压实。 腹板由具有驱动表面的辊向前驱动,每个驱动表面包括一系列围绕辊轴线仅沿一个方向螺旋地延伸的主腹板夹紧槽。 在辊的辊隙处,一个辊的槽的角度相对于幅材的行进方向正向倾斜。 另一个辊的角度相对于幅材的行进方向负向倾斜。

    • 本申请描述了采用一对驱动辊(10,12)的压实处理,所述驱动辊(10,12)限定用于向前驱动幅材(11)的辊隙和用于延迟幅材(11)向前进展的延迟器装置(16) 以使得幅材(11)在辊隙下游的辊(10,12)之间的空腔中压实。 卷材(11)由具有驱动表面的辊(10,12)向前驱动,每个驱动表面各自包括一系列主卷筒纸抓持槽,其仅在一个方向上螺旋地围绕辊轴线延伸。 在辊(10,12)的辊隙线处,一个辊的槽的角度相对于幅材(11)的行进方向正向倾斜。 另一卷的角度相对于卷筒纸(11)的行进方向呈负的倾斜。
