Abstract (en)
[origin: EP2554726A2] An opener for fibre in tufts comprises a first opener roller (32) and a second opener roller (52) beside the first. The first opener roller (32) is fed by a two transversally separate fibre flows (Fl,F2), which proceed axially towards the ends of the first roller, passing then onto the second roller and proceeding axially towards the centre thereof, from where they are expelled. The opener roller (32, 52) has portions fitted with pegs positioned along axially symmetric, respective imaginary helical lines.
