Abstract

PURPOSE:To obtain the titled hose having a reinforcing elongated member bonded securely thereto and with little defectives, by winding and securing around a hose discharged from a main die a rigid resin elongated member coated with a soft resin using a rotary die that rotates around the main die. CONSTITUTION:On the circumferential surface of the main die 2 for extruding a hose is slidably engaged the cylindrical rotary die 3, and two resin passages 8, 9 extend through the rotary die 3, whose forward ends meet in such a manner that a resin A running through one of them covers a resin B running through the other. A forward end 12 of a madrel 11 supported in the main die 2 by spokes 10 is extended beyond the front surface of the main die, and by the forward end 12, the rigid resin elongated member B coated with the soft resin A extruded from the rotary die is helically wound and secured around the tublar soft resin hose H discharged from the main die 2.
