Abstract: The rotary anvils herein may be used in combination with a tool member to perform various types of manufacturing operations, such as cutting, bonding, and embossing. The anvil roll may include a cylindrically-shaped outer circumferential surface and may be adapted to rotate about a first axis of rotation. More particularly, the anvil roll may include a body formed from a first material, such as a metallic material. The body may also include grooves in the outer circumferential surface, and abrasion resistant material may be fused to the body to fill the grooves to form strips. During operation, a tool member may be positioned to contact the strips of abrasion resistant material.

Abstract: An apparatus for embossing a web having a static gas pressure plenum and a forming structure disposed in contact to the static gas pressure plenum. The static gas pressure plenum provides a static gas pressure of from about 0.1 MPa to about 25 MPa.

Abstract: A process for making an embossed web. A precursor web is provided between a forming structure and a static pressure plenum. The forming structure has a plurality of discrete protruded elements. Pressure is provided by the static pressure plenum against the precursor web and the forming structure to conform the precursor web to the discrete protruded elements of the forming structure to form the embossed web. The resulting embossed web has a plurality of discrete extended elements having open proximal ends.

Abstract: A method for forming air-laid fibrous articles. The method includes the steps of providing a stream of loose air-entrained fibers, providing a core pocket assembly comprising a central foraminous forming surface and an edge foraminous forming surface, applying a first pressure to the central foraminous forming surface, applying a second pressure to the edge foraminous forming surface wherein the second pressure applied to the edge foraminous forming surface differs from the first pressure applied to the central foraminous forming surface, depositing a portion of the stream of loose air-entrained fibers on the central foraminous forming surface, and depositing a portion of the stream of loose air-entrained fibers on the edge foraminous forming surface.

Abstract: A method for forming air-laid fibrous articles. The steps of the method can include providing a stream of loose air-entrained first fibers, providing a core pocket operatively related to the stream of loose air-entrained first fibers, the core pocket including a central foraminous forming surface and an edge foraminous forming surface, applying a negative pressure to one of the foraminous forming surfaces, applying a positive pressure to the other foraminous forming surface, depositing the first fibers on one of the foraminous forming surfaces, providing a stream of loose air-entrained second fibers, operatively relating the core pocket to the stream of loose air-entrained second fibers, applying a negative pressure to one of the foraminous forming surface, and depositing the second fibers on that foraminous forming surface.
