摘要： PURPOSE:To provide device capable of producing a stripe tube with a stripe layer incorporated in a thick-wall part of a tube in an ideal state. CONSTITUTION:Nozzles 4 supplying a stripe layer material 13 to be incorporated in a base resin 12 are disposed in a base resin flow path 30 provided from an extruder to a molding die 2. A recessed part 31 is formed positionally correspondingly to the nozzles 4 for enlarging the flow path 30. Since the pressure of the base resin 12 is not applied to the stripe layer material 13 at the supply parts thereof, the flow of the stripe layer material 13 is not deformed and, therefore, a stripe layer having a desired cross-sectional shape can be obtained.

摘要： PURPOSE:To prevent the generation of a flaw part of mechanical strength on the surface of a hollow long member inclined in rigidity in its longitudinal direction at the time of production. CONSTITUTION:The emitting ports of first and second polymer supply parts 1, 2 as supply means of polymers different in elastic modulus are connected to the passage F reaching a long land die 5. A fluid supply nozzle 7 emitting a fluid for forming a hollow part is arranged in the polymer supply passage 110 between the confluent part 3 in the passage F of the polymers emitted from the polymer supply means and the first polymer supply part 1. The long land die 5 is constituted so that the inner surface thereof is coated with the molding aid emitted from a molding aid supply part 4. Since the nozzle 7 is arranged on this side of the confluent part 3, a seam line where polymers of a different kind remain is not generated in the obtained long member.
