ABSTRACT:
Apparatus for longitudinal compressive treatment of a continuous web of material. The apparatus comprises a cylindrical drive roll for advancing the web, a smooth-surfaced primary member to press the web against the drive roll, and a generally-stationary retarder 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 and grooves 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.
