  • Publication number: 20170341256
    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.

  • Patent number: 8926890
    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.

  • Patent number: 7704439
    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.

  • Patent number: 7704441
    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.

  • Patent number: 7553146
    Abstract: An apparatus for forming air-laid fibrous articles. The apparatus can have a core pocket. The core pocket can have a shield. The core pocket can further have a central opening defined by a void in the shield. The core pocket can further have a central forming chamber in air-flow communication with the central opening and having a central forming chamber periphery. The core pocket can further have a central foraminous forming surface in air-flow communication with the central forming chamber. The core pocket can further have a pair of edge openings extending along the shield. The core pocket can further have an edge forming chamber disposed about the central forming chamber periphery and in air-flow communication with the edge openings. The core pocket can further have an edge foraminous forming surface in air-flow communication with the edge forming chamber.
