Abstract: A method for making a composite web comprises the steps of



melt blowing a first flow of thermoplastic material including said first thermoplastic material towards at least one collecting suction surface moving in a feed direction;
dispensing a flow of particulate material including a particulate material towards the collecting suction surface in such a way as to intercept the first flow of thermoplastic material in an intercept zone; the first flow of thermoplastic material and the flow of particulate material intercept each other in the intercept zone at an intercept angle of between 1 and 90 sexagesimal degrees, preferably between 15 and 40 sexagesimal degrees.
