    Abstract: A machine and method for treating a web by longitudinal compressive 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.

    Abstract: A suction conveying device which has a belt conveyor and at least one vacuum chamber extending parallel to the conveyor belt characterized by an obturator engaging an upper surface of the vacuum chamber to close the opening therein when a blank is not engaged thereon. The obturator is preferably a resilient sheet of spring steel which is lifted from a position closing the openings by the movement of a blank across the opening.
