Abstract

PURPOSE:Temperature and pressure detectors are concentrated in and near a rectangular pipe on the way of the path for molten resin and signals therefrom are utilized to control accurately the temperature and pressure of resin with quick responce. CONSTITUTION:Pressure control valve 16 is equipped at the entrance of rectangular pipe 18 with an aspect ratio of 1.5-5, which is fitted between entrance pipe 7 of head 1 and outlet pipe 8, in the direction of the longer side of pipe 18. Temperature and pressure detectors 4, 5 are provided at the outlet side in the direction of the shorter side of pipe 18 and thermocouple 6 for detecting the temperature of head is fitted near pipe 18. The temperature of resin is controlled to a constant degree by feeding back signals from detector 5 through temperature indicator 13, cascade controller 14 to the temperature controller of the extruder. Further, signals from indicator 13 are input through setting signal circuit 17 in temperature controller 11 of head to control heater 2 along with signals from thermocouple 6, thus making the temperature of head the same as that of resin. The pressure of resin is controlled by changing depth h of pressure control valve 16 with signals from detector 4 through pressure controller 12.
