Abstract

PURPOSE: To prepare a flexible hose of good quality by a method wherein in the manufacturing method of gum flexible hose, of which pipe wall a hard resin spiral auxiliary core is buried in, a heat insulation layer is formed outside a cross head nozzle for hard resin to compound the resin having a big extruding molding temperature difference and gum.
CONSTITUTION: A hard nozzle 6, of which the base end is connected with the extruder head is set into the cross head 5 so as to position its tip 7 near the outlet of the cross head 5 die 8 and the nozzle 6 outer circumference is furnished with a heat insulating layer 10 consisting of glass wool, asbestos and the like. The hard vinyl chloride 2 for reinforcing an auxiliary core extruded from the extruder 1 nozzle 6 is coated with nitril 4 extruded from the extruder 3 to form a gum bandlike body T for extruding from the cross head 5 die 8. Next the bandlike body T is made to spirally advance by winding on a molding roll group 14 of the hose molder 11 to adhere adjacent side edges each other, then is made to pass through the heating device 17 for hardening thus to form the gum flexible hose H with the reinforced core.
