Abstract:

The facilities described in this paper can be used for the same plastic in two different colors. They can, as has been pointed out, be used where two entirely different plastic materials are employed, such as polyethylene and PVC. Two or more conductors can, of course, be coated simultaneously, if the need arises. Moreover, either extruder can be operated entirely as a separate unit by simply inserting the proper tool assembly. The space occupied by the multicoat extrusion facilities, in terms of product turned out, is only about half of what would be required if two separate operations are employed. The saving in investment costs, on the same basis, would be about 40 of the cost of conventional equipment. Substantial operating economies over conventional equipment will result through reduced scrap, maintenance and the more efficient utilization of labor. Author
