Abstract

660,734. Extruding tyres &c. UNITED STATES RUBBER CO. July 22, 1949 [Sept. 21, 1948], No. 19326/49. Class 87 (ii) Apparatus for .extruding composite articles comprises several independent extruders communicating by means of passageways with a common die head, an adjustable wall portion being positioned between two of the passageways for defining the junction between two parts of the composite article. The three passageways 17, 18, 19 are connected to feed screws, not shown, and are supplied respectively with black rubber for forming the inner side and undertread 12, Fig. 2, with hard-wearing rubber for the tread 11, and with white rubber for forming the outer side 14. The position of the junction 15 between the white and the black rubber is determined by the position of a block 31 mounted on a longitudinally adjustable bar 30 which extends the full length of the die opening. The bar is adjusted by means of a screw 37. The parts of the die are detachable and are held in place by a number of clamps 46. The cross-section of the extruded article is determined by the profile of plate 45 forming part of the die. Another part of the die, plate 48, is adjustable to vary the width of the die cavity and determines the thickness of the undertread. The various parts of the extrusion head have cavities for the circulation of heating or cooling fluid.
