ABSTRACT:
Disclosed is a process for fabrication of elastomer or plastomer tubes from sensitized aqueous dispersions wherein the tube is extruded through a shaping apparatus. Heated air is discharged into the tube as it is extruded, with the heated air flowing axially through the tube to vaporize and remove serum exuded into the tube as the gelling process continues. The tube, having the heated air flowing therethrough may be passed through a washing vat to remove serum from its external surface.
