摘要： A method and apparatus are disclosed for binding a nonwoven material by means of a binding agent requiring heat for activation, particularly for binding cellulosic fibers with a thermoplastic material. The material is irradiated with an infrared radiation source, and surface burning of the irradiated material is prevented by passing a weak flow of air through the material. Inclined walls guide the air flow through the material in an inclined path directed from the edge of the infrared radiation source and towards the center thereof. Each infrared radiation source is surrounded by two side walls so that a space is formed between each side wall and the radiation source for the passage of the inlet air. The cross-sectional areas of these spaces are together approximately equal to the cross-sectional area of a suction channel positioned opposite the spaces. The air flow is controlled by means of two speed-regulated fans, one at the inlet and one at the outlet of the apparatus.
