US Patent:
39543668, May 4, 1976
Filed:
Jan 6, 1975
Appl. No.:
5/538755
Inventors:
Reuben T. Fields - Claymont DE
International Classification:
B29F 302
US Classification:
425208
Abstract:
A two-stage single screw apparatus and process for the extrusion of plastic resins, the first stage positively advancing the resinous material while in a highly viscous state with minimum blow-back and the second stage, through the use of a screw having multiple lead threads with a high pitch adapted to allow substantial blow-back to provide mixing and ultimate discharge of the resin through die means, providing precise metering and discharge of the molten resin through the die over a wide variation of die pressures.
