Claims

[Scope of utility model registration request]

(1) A spindle disposed in the unvulcanized rubber flow path along the axes of the die head and the die, with its tip protruding from the extrusion port of the die, and the die and the spindle disposed outside the extrusion port of the die. In the extruder, the extruder includes a marking roll that is disposed opposite to the spindle along the axis of the Googly head and is rotatably supported in the extrusion direction, the spindle having a rear end connected to a cooling water supply source. An extruder for rubber tubes.

(2) The extruder according to claim (1), wherein the fulcrum of the marking roll is located on a reference plane with reference to the open end face of the die or in a parallel plane within ±3rrvn from the reference plane.
