Abstract

Improvements in machines for manufacturing a continuous sheet of multilayer paper, according to a method comprising a first step for continuously depositing, on a continuous web of fabric moving in a substantially straight direction, a first layer of a suspension of a fibrous material suitable for generating a first layer of paper, means being arranged below said cloth band that are apt to exert, through the cloth band, a predetermined aspiration on said first layer to remove from it a predetermined quantity of the liquid of said suspension, and at least a second stage to continuously deposit, on said first layer, a second layer of said fibrous material suspension, which is apt to generate a second layer of said papal sheet, the second layer of suspended material being formed on the outer surface of a cloth-covered rotary forming cylinder provided with means suitable for eg a predetermined suction on said second layer of material to remove a predetermined quantity of the liquid from said suspension, characterized in that the machine comprises a continuous web of fabric, mobile in a substantially straight direction, first supply means to continuously form, on said fabric band, a first layer of a suspension of a fibrous material that is apt to generate a first layer of said sheet of paper, at least one rotary forming cylinder covered with fabric and kept in contact with said fabric band, and second supply means for forming, on said fabric of the forming cylinder, a second layer of a suspension of a fibrous material that is apt to generate a second layer of said sheet of paper, said second layer of material being deposited by said cylinder former on said first layer of material.
