Abstract

1,038,100. Automatic process control. INDUSTRIAL NUCLEONICS CORPORATION. Dec. 24, 1964 [Dec. 26,1963], No. 52436/64. Heading G3R. In an automatic system for controlling the throughput of a continuous plastic extrusion process is determined by computation from the weight per unit area, speed and width of the product and the difference from a reference valve is used to control a plastic supplying device. As shown, plastic in a hopper 46 is fed by a screw 52 through a linear die 49 to produce a sheet 50 which is polished by rolls 54 and pulled from the die by rolls 56. The weight per unit area of the sheet is sensed by a radiation gauge 60 which, through a measuring and averaging circuit 62 and controller 66 controls motors 67, 68 driving rolls 54, 56 respectively. Signals representative of width, from a gauge 72, and sheet speed, from a tachogenerator 76, are processed in a throughput computer 70 together with the weight per unit area signal from circuit 62. The throughput signal controls an extruder screw motor 48 to maintain the feed from hopper 46 at the desired computed throughput valve.
