Abstract

1,066,806. Temperature regulation of extrusion apparatus. P. G. MULAS. Dec. 30, 1963 [Jan. 15, 1963], No. 51216/63. Heading B5A. In apparatus for extruding thermoplastic resins and the like comprising a plasticizer 1, an extrusion nozzle 3 and an extrusion screw 4, helicoidal grooves 6, 7 and 8 on the plasticizer and nozzle and a helicoidal groove (not shown) in the screw are connected to conditioning stations which control the heating and cooling of fluid flowing in the grooves to maintain different but constant temperatures in the apparatus. The conditioning stations are controlled by voltage impulses from thermocouples 23 intermediate the ends of the groove sections. The groove 6 is divided into independent sections 14, 15, 16 by insulated parting blocks (17), Fig. 2 (not shown). The apparatus is surrounded by jackets 18, 19, 20, which are coated with insulating material and separated by insulating material 21.
