Abstract (en)
Plant for producing nonwoven fabric, which comprises a main channel (3) susceptible of being traversed by extruded filaments (F) for forming a nonwoven fabric, and a cooling station (8), which defines, in the main channel (3), a cooling channel (9). The cooling station (9) is composed of two pairs of superimposed chambers (100, 120) placed on opposite sides of the cooling channel (9), and of a common homogenization chamber (90) in which the air coming from the two superimposed chambers (100, 120) converges. In each chamber, a plurality of homogenizing plates (80) is provided while in the common chamber (90) a straightener panel is provided preceded by further homogenizing plates (93). The ratio between the first section (S1) of the upper first chamber (100) and the second section (S2) of the lower second chamber (120) is comprised between 3/6 and 5/6 and preferably is approximately 4/6.
