    • Apparatus for longitudinal compressive treatment of a continuous web of material. The apparatus comprises a cylindrical drive roll (100) for advancing the web, a smooth-surfaced primary member (112) to press the web against the drive roll, and a generally stationary retarder (114) downstream of the primary member to engage and retard the web before the web has left the drive roll. The retarder surface has a large multiplicity of parallel ridges (202) and grooves (204) set on a diagonal, and effective to cause longitudinal compression of the web and to cause the web to flow at an angle to the original direction of drive. The retarder surface also has a reorienting retarding surface, effective after the web advances incrementally at the angle, to effect further compression and to reorient the travel of the web to be generally parallel to the original direction of drive.
    • 用于纵向压缩处理连续材料网的装置。 该装置包括一个用于推进幅材的圆柱形驱动辊(100),一个平滑表面的主要构件(112),以将幅材压靠在驱动辊上,以及在主要构件下游的大体上固定的延迟器(114) 网络已经离开驱动器卷之前的网络。 缓速器表面具有大量平行的脊(202)和设置在对角线上的凹槽(204),并且有效地引起幅材的纵向压缩并且使得幅材以与原始驱动方向成一定角度流动。 延迟器表面还具有重新定向的延迟表面,在幅材以角度渐进地前进后进行有效的,以进一步压缩并且将幅材的行进方向重新定位成大致平行于原始驱动方向。
