ABSTRACT:
In the method for manufacturing a product in the form of a mat containing mineral fibers and a binding agent, the binding agent is mixed with the fibers before the formation of the product. The material used as the binding agent includes thermoplastic particles, such as fibers, a powder, or particles in a dispersion, which are supplied to the fibers being formed of melted mineral into the stream of air. The fibers and the binding agent are carried by a turbulent air flow, in which the heat contained in the melting mineral and the fibers forming therefrom are used for melting or softening thermoplastic particles into a state, in which they effect the binding of the fibers to each other.
