A process for applying a coating (M) of a material onto a web (W) includes the step of providing a source ( 6 ) of the material to be coated in the fluid state. The source includes one or more output nozzles ( 11 ) for emitting the coating material in the fluid state in a first direction (X 1 ). A drive unit produces a relative movement of the output nozzle ( 11 ) with respect to the web (W), such a movement taking place in a second direction (X 2 ). The first (X 1 ) and second (X 2 ) directions form an angle (alpha) therebetween of less than 45°, and preferably about 5°. The web is preferably kept flat and extending in the second direction (X 2 ) at the region where the coating material (M) is applied onto the web (W) and the output nozzle ( 11 ) is positioned with respect to the web (W) in such a way that, in travelling from the nozzle ( 11 ) to the surface of the web W being coated, the coating material (M) follows a free path over a given distance (d).
