Abstract

A melt-blown type non-woven fabrics making plant (1) is provided, comprising a distributor (2) including at least one main access (20) suitable to convey polymeric fluid and a plurality of secondary accesses (21) suitable to convey gas; a dispenser (3) in fluid passage connection with the distributor (2), configured to dispense polymeric filaments starting from the polymeric fluid and including at least one spinneret (4) suitable to form the polymeric filaments and an air blade (5) suitable to receive the gas to guide the polymeric filaments exiting the dispenser (3), wherein the spinneret (4) comprises a plurality of flanked pinnacles (40) and each one comprising one main outlet (40a) configured to convey the polymeric fluid towards a respective delivery direction (4a), and for each pinnacle (40) a pair of secondary outlets (41) arranged at opposite sides of the respective pinnacle (40) and configured to convey the gas towards the air blade (5), wherein the air blade (5) is suitable to convey jets of gas to converge towards each delivery direction (4a), and wherein the plant (1) further comprises a transfer device (6) configured to place in fluid passage connection the at least one main access (20) with at least one main outlet (40a) and each secondary access (21) with at least a respective secondary outlet (41).
