ABSTRACT OF THE DISCLOSURE A suitable number of cords are supplied from a cord feeder to an extruder, passed through the crosshead of the extruder and coated with a raw rubber material. The rubber-coated material is pulled by a pull roll assembly disposed downstream from the extruder and wound up on a take-up assembly disposed downstream from the pull roll assembly. The winding speed of the take-up assembly is adjusted in accordance with the line speed and the variation in the diameter of wound-up coated material. A liner is supplied from a liner feeder to the take-up assembly and interposed between the portions of the coated material wound up. When the liner being drawn out for use in winding the rubber coated cords around the take-up drum approaches its rear end, another new liner is arranged so as to adhere automatically to the running liner without making any stop to the rubber coating operation.
