Abstract
An apparatus includes a forming section for forming a web from stock. The apparatus also includes a press section which is disposed downstream relative to the forming section for removing a portion of water from the formed web. The press section includes a suction pick-up roll disposed downstream relative to the forming section for picking up the formed web from the forming section. A press felt extends around the suction pick-up roll such that in use of the apparatus, the formed web is picked up from the forming section and is supported by the press felt. An extended nip press is disposed downstream relative to the pick-up means. The press includes a rotatable backing roll and a pressing shoe which cooperates with the backing roll for defining therebetween an elongate pressing section. A bearing blanket movably extends through the pressing section with the blanket cooperating with the suction pick-up roll such that the formed web is transferred from the press felt to the blanket. The apparatus also includes a dryer section which includes a rotatable dryer having a heated surface which cooperates with the blanket such that the pressed web is transferred from the blanket to the heat…
