Abstract (en)
[origin: EP3865613A1] Plant (1) for producing nonwoven fabric, comprising a main channel (3) extended along a vertical axis (Y), an adjustment station (7), which comprises at least two stretch walls (9), which are extended opposite each other and are provided with two respective internal faces (9') which define between them a stretch section (8) in the main channel (3) and two opposite external faces (9") externally directed with respect to the main channel (3), first deformation means (10) mechanically constrained to the external faces (9") of the stretch walls (9) in order to deform the stretch section (8) of the main channel (3) and comprising at least one first deformable member (11') mechanically fixed on the external face (9") of a first stretch wall (9A) and extended at least along a first transverse axis (X') orthogonal to the vertical axis (Y), at least one second deformable member (11") mechanically fixed on the external face (9") of a second stretch wall (9B) and extended at least along a second transverse axis (X") orthogonal to the vertical axis (Y) and parallel to the first transverse axis (X'), the first deformable member (11') and the second deformable member (11") are actuatable at least between a rest configuration, in which they are extended substantially parallel to each other and a deformation configuration, in which they define two corresponding curved profiles, in order to vary the shape of the stretch section (8) of said main channel (3).
