ABSTRACT:
A method for forming a dry web on the wire, with the fibre material being fed into at least one perforated drumlike forming element that covers essentially the whole width of the web to be formed, in which forming element fibres are conveyed in the drum along the width of the web and screened through the mantle of the forming element onto the wire. To achieve such web formation as has as few disturbances as possible, the fibre material is fed into the drumlike forming element in such a way that the bulk of the fibres, when advancing in the feeding direction toward the other end of the forming element, get screened from the forming element onto the wire, and that those fibres that do not get screened, but travel through the forming element are removed from the forming element and returned for a new defibration.
