Title: HEAD FOR DISPENSING FLUID MATERIAL
Abstract:
Head for dispensing fluid material. Head for dispensing fluid material (T) comprising a spraying wall (26) perforated with a network of holes (O) through which the pressurised fluid material passes so as to be sprayed in fine droplets, characterised in that the network of holes (O) comprises at least two rows of holes (O), with the holes (O) of the same row having a substantially identical hole size, and with the holes (O) of different rows having different hole sizes, such that a row of holes (O) generates a spray of fine droplets with a distribution of droplet sizes defining a first Gaussian distribution, while another row of holes (O) generates a spray of fine droplets with a distribution of droplet sizes defining a second Gaussian distribution, which is staggered with respect to the first Gaussian distribution, thus producing a complex spray with at least two separate Gaussian distributions.
