Abstract: A two-shaft continuous mixing apparatus includes a housing containing two rotors having substantially horizontally aligned centerlines and a material passage formed so as to communicate with a mixing chamber in which the rotors rotate, the material passage extending nearly horizontally from a discharge port of the mixing chamber. The material passage has an upper surface forming an edge with the mixing chamber, and a lower surface forming an edge with the mixing chamber. The material is thereby scraped off the edges and flows through the material passage as the rotors are rotated.

Abstract: A steel-pipe coating process and an apparatus therefor, in which molten resin is extruded through a cross-head die connected to an extruder, into a tubular shape, in a manner to cover or coat the surface of a steel pipe. In this apparatus, a resin outlet in the extruder is communicated through the medium of a resin guide member with a resin inlet of the cross head die. The extruder is secured to a fixed frame, while the cross head die is supported by the fixed frame in a reciprocating manner through the medium of a reciprocating drive member within a given stroke in the direction of the steel pipe being fed. Thus, when the cross head die is reciprocated by means of the reciprocating drive member, the relative speed of the steel pipe being fed to the cross head die being reciprocated may be intermittently varied, whereby the amount of resin being extruded through a cylindrical outlet of the cross head die around the surface of the steel pipe may be intermittently varied.
