Method Of Controlling Thickness Of Thermoplastic Extruded Profile
Method Of Controlling Thickness Of Thermoplastic Extruded Profile
US Patent:
5112546, May 12, 1992
Filed:
May 10, 1991
Appl. No.:
7/698286
Inventors:
Gordon A. Comfort - Tecumseh MI
International Classification:
B29C 4720
US Classification:
264167
Abstract:
A process is described for precisely controlling the thickness of a thermoplastic extruded profile by varying the output of a continuously operating extrusion die. The process employs an ancillary device preferably taking the form of accumulator means connected to an extrusion die, or to a passageway communicating with the die. The accumulator means functions as a variable volume device, and by action of cylinder-piston structure or the equivalent thereof, is effective to either receive or discharge melted thermoplastic resin as the exemplary working medium. In this manner, the accumulator means receives melt from the stream when the die output needs to be reduced, and delivers melt to the stream when the die output needs to be increased. Various illustrative structural arrangements are disclosed for accomplishing the process concepts of the present invention.
