Rubber Extrusion | Universal Polymer & Rubber | Custom
Rubber extrusion is an efficient and economical manufacturing process. The volume of wasted material in the extrusion process is minimal, and the production costs are typically lower when compared to other production methods. Rubber extrusion is a continuous process that can produce finished products of different lengths in a variety of shapes.
Process and apparatus for producing rubber hose with
FIELD OF INVENTION. The present invention relates to a process and apparatus for the production of rubber hose and tubing with a textile thread insert or reinforcing in which an inner layer of material is extruded, this extrusion is cooled, then surrounded with textile thread whereupon a second layer is applied by extrusion as a covering and the resulting hose is thereupon vulcanized.
