摘要： The tubular extrusion of a thermoplastic nonderivatized cellulose solution about a mandrel and through a long air gap in excess of 304 mm is facilitated by use of a mandrel which is extensible from the extrusion die. On extrusion start-up, the mandrel extends a short length from the die. For steady-state operation, the mandrel is extended its full length from the die. Also disclosed is a mandrel structure to facilitate the introduction of a nonsolvent liquid into the interior of the extruded tube at a high location on start-up of extrusion and at a lower location during steady-state operation. The mandrel also includes a sizing portion having circumferential grooves which gather gas bubbles that may evolve at the interface between the extruded tube and the sizing portion. Vertical channels in the sizing portion connect these grooves and provide the passage of gas bubbles into a volume below the mandrel.

摘要： A backup roller assembly having a plurality of rollers for applying pressure to an inside surface of a photoreceptor web, and a process for making such backup rollers is disclosed wherein a thin walled tube is extruded from a metallic or polymeric material. After extrusion, the tubing is cut to a desired length and filled with a filler, preferably a urethane foam for providing support for the thin-walled tubing, for the adhesion of journals at each end of the tube and for grounding the photoreceptor web. After the journals are attached at each end of the tubing by the adhesion of the foam, the backup roller can be ground to a precise outer diameter. In a final step, the journals are machined to the proper specifications.

摘要： A synthetic-resin tube as it emerges longitudinally from an extruder is passed over a two-part mandrel. A coolant such as water issuing from the upstream part of the mandrel passes axially downstream around the mandrel and is drawn into openings at the downstream part of the mandrel to draw the tube inwardly by suction toward the mandrel and impart to this tube the exact shape of the mandrel. Either or both of these parts may be formed as a longitudinal succession of transverse vanes having external peripheral shapes corresponding to the desired internal shape to be imparted to the tube. It is also possible to form either or both of the parts of the mandrel as a hollow cylindrical body formed with intake or output openings constituted as slits running either in the direction of travel or transverse thereto.

摘要： Hollow synthetic board which may be used to replace corrugated paper board is continuously extruded of relatively soft thermoplastic resin, such as polyolefin, by apparatus having replaceable mandrels disposed in the cavity of an extrusion die. These mandrels are fastened in operative position by hollow screws which are part of the passage means for maintaining the interior of the synthetic board at ambient pressure. After leaving the die the extrusion alternately passes through a plurality of cooling and sizing sections. In the latter a vacuum is applied to the outer surface of the board to prevent collapse thereof prior to hardening of the extrusion. Temperature within the cooling sections is regulated so that the upstream sections are warmer than the downstream sections.
