<p>A method and device for the dewatering of a fibre suspension, the suspension from above being introduced into an elongate tubular vertically orientated container of a fibre separation material such as wire cloth, the container being formed of a wider endless flexible wire band and a more slender endless flexible wire band, which mutually are lap joined at adjacent border parts, which carry a respective part of a Velcro coupling, the cross section of the wider band being reshaped to C-shape, by folding the two border parts thereof in over one of the main surfaces, and the folded border parts of the wider band are brought into overlapping contact with the overlapping border parts of the extended more slender band. The screening pipe is established along a common longitudinal section of the tracks of the two wire bands, the lower end part of the screening container being kept substantially sealed, and the fibre suspension being introduced by elevated pressure to a nozzle assembly which is centrally placed in the screening pipe, the fibre suspension being led out from the nozzle assembly via a number of spray nozzles spaced-apart around the nozzle assembly, toward the inside of the screen pipe.</p> |
