Abstract

1396001 Reinforced tube extrusion die UKRAINSKY NAUCHNO - ISSLEDOVATELSKY I KONSTRUKTORSKY - INSTITUT PO RAZRABOTKE MASHIN I OBORUDOVANIA DLYA PERERABOTKI PLASTICHESKIKH MASS REZINY I ISKUSSTVENNOI KOZHI 28 June 1972 30170/72 Heading B5A A tube 8 comprising inner and outer thermoplastics layers enclosing a reinforcing hose 7, is extruded from a die head including a tubular through passage for the hose 7, terminating at a die outlet in which the surface of the inner thermoplastics layer is defined by a cylindrical surface 15 of the mandrel which is located downstream of the end face of a surrounding die 3 which defines the surface of the outer thermoplastics layer. The thermoplastics from an inlet 9, is supplied to the die outlet via a frusto-conical passage 10, and a chamber 13 which is externally and internally enlarged with respect to the outlet, to permit passage of the thermoplastics through the hose to form the inner layer, and which is defined internally by a mandrel groove having longitudinally extending ribs 14 and joining to the cylindrical surface 15 downstream of the die 3 at a frusto-conical surface 16. The extruded tube 8 is drawn from the die around the rounded surface of a sizing mandrel 19, of greater diameter than the surface 15 and which is supported from the die head mandrel by a rod 18. The tube is cooled upstream of the mandrel 19, by air or water from a device 20.
