Abstract
An extended nip press apparatus is disclosed for pressing water from a web of paper. The press includes a blanket which defines an endless loop and a first and a second lateral edge. Edge seals cooperate with the edges for sealing the edges of the blanket against egress of lubricant disposed between the shoe and the blanket. The edge seals include a head rotatably secured to a frame and an extension which extends from the head. The extension cooperates with the first edge of the blanket and defines a duck's bill configuration in a cross-machine sectional view such that the first edge of the blanket conforms to a surface defined by the extension. The surface has a first portion which undulates radially away from the head in an outward direction, and a second portion which undulates radially inwardly towards the head in an outward direction. A clamp adjustably secures the first edge of the blanket to the extension so that flow of lubricant from between the shoe and the blanket past the head is inhibited.
