LONGITUDINAL COMPRESSIVE TREATMENT OF WEBS Abstract of the Disclosure A machine and method for treating a web by longitudinal commpressive action, by pressing a web against a driven roll to drive it into a treatment cavity bounded by the roll and an overlying surface, followed by application of retarding forces by extrusion in which the extrusion orifice is arranged with its axis substantially parallel to the roll at the web-drive point, and in which resilient self-adjustment of the extrusion orifice is achieved by employing a plate-form member parallel to the web which is resiliently urged toward the drive nip in the direction of extent of the plate-form member.
