Abstract
Abstract An apparatus for treating or processing textile cord, especially cords suitable for reinforcing pneumatic tires. The apparatus has a number of vertically stacked and spaced gas-fired burners with exposed flames for emitting infrared radiation. A continuous textile cord, or sheet of textile cord fabric is moved through the apparatus in heat-receiving relation past the exposed flame of burners. A screen or shield with adjustable openings is interposed between the moving cord and each burner for regulating the infrared radiation impinged on the cord. A sensor, responsive to the temperature of the cord, is utilized for changing the size of the openings of the shield to control the environment or heat conditions in which the cord is processed.
