摘要:
A roll for molding a fibrous sheet. The roll includes a rotatably driven cylindrical shell. The cylindrical shell includes an interior surface, an exterior surface, and a permeable patterned surface on the exterior surface of the shell. The permeable patterned surface has at least one of a plurality of recesses and projections, a plurality of holes extending from the exterior surface to the interior to allow air to be moved through the shell. Each hole has an exterior end and an interior end, and a plurality of grooves. Each groove is fluidly connected to the exterior end of each hole and extends outward from the corresponding hole. The roll also includes a vacuum box on the inside of the cylindrical shell to draw air from the exterior surface of the shell to the interior surface. The vacuum box is stationary with respect to the rotation of the shell.
